RESUMEN

Cattle raising is a crucial element of production systems in the tropics and subtropics. However, in recent years, global public health security has been threatened by disease emergence. In Orellana Province, livestock is the most important activity to generate economic income. Nevertheless, there is no available data about Animal Health status. With this objective, a study was performed to describe the major Bovine diseases recorded between 2011 to 2019, and the main Risk factors associated. Data on main Bovine diseases were retrieved from the World Animal Health Information System database. Whereas Bovine population data used to calculate the prevalence rates and confidence intervals were obtained from Ecuador's Ministry of Agriculture. By contrast, the Risk factors identified with an epidemiological questionnaire were applied to 300 livestock farmers. As a result, from 2011 to 2019 in Orellana has been confirmed: 90 cases of Infectious Bovine Rhinotracheitis (31.58%), Bovine Rabies by hematophagous bats (Desmodus rotundus), 83 cases (29.12%), Bovine viral diarrhea with 43 cases (15.10%), Brucellosis by Brucella abortus 35 cases, which was (12.28%), and 34 cases related to Enzootic bovine leukosis (11.92%). Overall, the prevalence rates ranged from (0.24 to 15.37%). In addition, farm size, presence of forest, herd, and paddock sizes, cutting frequency of forages, and other animal species were involved as Risk factors (OR = 3.15 to 11.75; 95% CI, 0.01 to 0.69). In conclusion, there are animal diseases with reproductive and neurologic symptomology and high-Risk factors implicated in the transmission. Consequently, space-temporal and seroprevalence epidemiological studies should be performed in Orellana.

A criação de gado é um elemento crucial dos sistemas de produção nos trópicos e subtrópicos. No entanto, nos últimos anos, a segurança da saúde pública global tem sido ameaçada pelo surgimento de doenças. Na província de Orellana, a pecuária é a atividade mais importante para gerar renda econômica. Contudo, não há dados disponíveis sobre o estado de saúde animal. Com este objetivo, foi realizado um estudo para descrever as principais doenças dos bovinos registradas entre 2011 e 2019, além dos principais fatores de risco associados. Os dados sobre as principais doenças bovinas foram recuperados do banco de dados do World Animal Health Information System. Os dados da população bovina usados para calcular as taxas de prevalência e os intervalos de confiança foram obtidos do Ministério da Agricultura do Equador. Por outro lado, os fatores de risco identificados com um questionário epidemiológico foram aplicados a 300 criadores de gado. Como resultado, de 2011 a 2019 em Orellana foram confirmados: 90 casos (31,58%) de rinotraqueíte infecciosa bovina, 83 casos (29,12%) de raiva bovina por morcegos hematófagos (Desmodus rotundus), 43 casos (15,10%) de diarreia viral bovina, 35 casos (12,28%) de brucelose por Brucella abortus e 34 casos relacionados à leucose enzoótica bovina (11,92%). No geral, as taxas de prevalência variaram de 0,24 a 15,37%. Além disso, tamanho da fazenda, presença de floresta, tamanho do rebanho e dos piquetes, frequência de corte de forragens e outras espécies animais estiveram envolvidos como fatores de risco (OR = 3,15-11,75; IC 95% 0,01-0,69). Em conclusão, existem doenças animais com sintomatologia reprodutiva e neurológica e fatores de alto risco implicados na transmissão. Portanto, estudos epidemiológicos espaço-temporais e de soroprevalência devem ser realizados em Orellana.

RESUMEN

This study aimed to evaluate the demographic and healthcare situation of dogs and cats owned by families assisted by the Family Health Strategy (FHS), from Santa Maria/RS, Brazil. This research was a cross-sectional and population-based study developed by applying a questionnaire to residents in the 16 FHS areas of the city. This was the first study addressing pet animal conditions in the FHS area. A total of 414 households were studied, and 88.5% of them had pets (dogs and/or cats), with an average of 2.2 dogs and 0.8 cats per household. Only 18.4% (228/1.241) of the animals were sterilized (dogs, 15.1% [135/891]; cats, 26.7% [93/348]). When considering the number of dogs, households with one resident had fewer dogs than households with two or more residents (p=0.006). The level of education and family income were not associated with the number of animals (p>0.001). However, higher levels of education and family income were associated with the sterilization of dogs, veterinary monitoring, vaccination, and treatment of ectoparasites in dogs and cats (p<0.0001). Additionally, the higher family income was associated with a higher frequency of endoparasite treatment (p<0.05). The study shows a high average number of pets per household in FSH areas compared to the average household population as well as a lack of veterinary care, making it essential to promote responsible custody.

Este estudo teve como objetivo avaliar a situação demográfica e de saúde de cães e gatos pertencentes a famílias assistidas pela Estratégia de Saúde da Família (ESF), de Santa Maria/RS, Brasil. Esta pesquisa foi um estudo transversal baseado na população adscrita, desenvolvido por meio da aplicação de questionário aos residentes das 16 áreas de ESF da cidade. Este foi o primeiro estudo que abordou as condições dos animais de estimação na área de ESF. Foram estudados 414 domicílios, e 88,5% deles tinham animais de estimação (cães e/ou gatos), com uma média de 2,2 cães e 0,8 gatos por domicilio. Apenas 18,4% (228/1,241) dos animais foram esterilizados (cães, 15,1% [135/891]; gatos, 26,7% [93/348]). Ao considerar o número de cães, os lares com um residente tinham menos cães que os lares com dois ou mais residentes (p=0,006). O nível de educação e a renda familiar não estavam associados ao número de animais (p>0,001). Entretanto, níveis mais altos de educação e renda familiar foram associados com a esterilização de cães, monitoramento veterinário, vacinação e tratamento de ectoparasitas em cães e gatos (p<0,0001). Adicionalmente, a maior renda familiar foi associada a uma maior freqüência de tratamento endoparasitário (p<0,05). O estudo mostra um alto número médio de animais de estimação por domicílio nas áreas de ESF em comparação com a população domiciliar média, bem como uma falta de cuidados veterinários, tornando essencial promover a custódia responsável.

RESUMEN

The use of antimicrobials in animals is broader compared to humans, which can influence the increase in microbial resistance. This study was a systematic review which determined the prevalence of resistant Enterococcus faecium in commercial cattle. Eighteen studies were included, mainly carried out in European countries (n=9) and in the production (n= 11) and retail (n= 7) environments. The main material used in the detection of the microorganism was milk. The mean prevalence of resistant E. faecium in cattle was 4.3% (95% CI = 2.8-5.0%), but the prevalence in Asia was higher [25.4% (95% CI = 20.5-30.6%)]. There was a higher prevalence in samples from retail (13.7%; 95% CI=11.5-16.1%) and collected mainly from equipment surfaces (12.5%; 95% CI= 5.5-26.1%) than in the others tested samples. Antibiotics frequently tested were vancomycin, tetracycline, ciprofloxacin, and erythromycin, with resistance percentages of 50%, 59%, 79%, and 94%, respectively. These results reinforce the need to plan interventions to reduce antimicrobials in food-producing animals.

O uso de antimicrobianos em animais é mais frequente quando comparado aos humanos, e isso pode influenciar no desenvolvimento da resistência microbiana. O presente estudo teve como objetivo realizar uma revisão sistemática cujo desfecho de interesse foi a prevalência de E. faecium resistente a antimicrobianos na bovinocultura comercial. Foram incluídos 18 estudos, realizados principalmente em países europeus (n=9), em ambientes de produção (n=11) e destinados ao varejo (n=7). O principal material utilizado na detecção do microrganismo foi o leite. A prevalência de E. faecium resistente em bovinos foi de 4,3% (IC 95% -2,8-5,0%), mas a prevalência na Ásia foi maior [25,4% (IC 95%=20,5-30,6%)]. Houve maior prevalência em amostras do varejo (13,7%; IC 95%=11,5-16,1%) e coletadas principalmente de superfícies de equipamentos (12,5%; IC 95%-5,5-26,1%). Os antibióticos frequentemente testados foram vancomicina, tetraciclina, ciprofloxacino, e eritromicina, com percentuais de resistência de 50%, 59%, 79%, e 94%, respectivamente. Estes resultados reforçam a necessidade de intervenções planejadas para reduzir a utilização de antimicrobianos nos animais criados para produção de alimentos.

RESUMEN

Working equids play an essential role in supporting livelihoods, providing resilience and income security to people around the world, yet their welfare is often poor. Consequently, animal welfare focussed NGOs employ a range of initiatives aimed at improving standards of working equid welfare. However, there is debate surrounding the efficacy of welfare initiatives utilised and long term monitoring and evaluation of initiatives is rarely undertaken. This study compares equid welfare and the social transmission of welfare information across Mexican communities that had previously received differing intervention histories (veterinary treatment plus educational initiatives, veterinary treatment only and control communities) in order to assess their efficacy. Indicators of equid welfare were assessed using the Equid Assessment Research and Scoping tool and included body condition score, skin alterations, lameness, general health status and reaction to observer approach. Owners were interviewed about their involvement in previous welfare initiatives, beliefs regarding equid emotions and pain, and the social transmission of welfare knowledge, including whether they ask advice about their equid or discuss its health with others and whether there is a specific individual that they consider to be 'good with equids' in their community. In total 266 owners were interviewed from 25 communities across three states. Better welfare (specifically body condition and skin alteration scores) was seen in communities where a history of combined free veterinary treatment and educational initiatives had taken place compared to those that had only received veterinary treatment or control communities. The social transfer of welfare knowledge was also higher in these communities, suggesting that the discussion and transfer of equid welfare advice within communities can act as a mechanism to disseminate good welfare practices more widely. Our results suggest that using a combined approach may enhance the success of welfare initiatives, a finding that may impact future NGO programming.

RESUMEN

Efficient planning of measures limiting epidemic spread requires information on farm locations and sizes (number of animals per farm). However, such data are rarely available. The intensification process which is operating in most low- and middle-income countries (LMICs), comes together with a spatial clustering of farms, a characteristic epidemiological models are sensitive to. We developed farm distribution models predicting both the location and the number of animals per farm, while accounting for the spatial clustering of farms in data-poor countries, using poultry production as an example. We selected four countries, Nigeria, Thailand, Argentina and Belgium, along a gradient of intensification expressed by the per capita Gross Domestic Product (GDP). First, we investigated the distribution of chicken farms along the spectrum of intensification. Second, we built farm distribution models (FDM) based on censuses of commercial farms of each of the four countries, using point pattern and random forest models. As an external validation, we predicted farm locations and sizes in Bangladesh. The number of chicken per farm increased gradually in line with the gradient of GDP per capita in the following order: Nigeria, Thailand, Argentina and Belgium. Interestingly, we did not find such a gradient for farm clustering. Our modelling procedure could only partly reproduce the observed datasets in each of the four sample countries in internal validation. However, in the external validation, the clustering of farms could not be reproduced and the spatial predictors poorly explained the number and location of farms and farm sizes in Bangladesh. Further improvements of the methodology should explore other covariates of the intensity of farms and farm sizes, as well as improvements of the methodology. Structural transformation, economic development and environmental conditions are essential characteristics to consider for an extrapolation of our FDM procedure, as generalisation appeared challenging. We believe the FDM procedure could ultimately be used as a predictive tool in data-poor countries.

RESUMEN

Objetivou-se com este estudo caracterizar as principais transformações ocorridas na pecuária leiteira entre as unidades federativas do Brasil no período de 2006 a 2017. Foram reunidos dados dos Censos Agropecuários de 2006 e 2017. Em seguida, foram feitas análises descritivas para comparação das variações entre estados e macrorregiões. Para testar o relacionamento das variáveis foi utilizado o teste de correlação de Pearson. Houve redução de 4,63% no número de estabelecimentos com bovinos, com destaque para os estados de PE (-23,02%), RS (-20,67%) e PR (-19,65%). Houve crescimento da participação de alguns estados no número de bovinos, especialmente da região Norte. A área de pastagem não mudou significativamente com o passar dos anos. Verificou-se redução de 12,92% no número de produtores de leite, principalmente em bacias leiteiras tradicionais, como RS (-36,62%), PR (-27,33%), SP (-24,67%) e SC (-20,21%). Os produtores que permaneceram na atividade aumentaram sua escala de produção diária. Embora houve decréscimo de 9,47% no número de vacas ordenhadas, a produtividade do rebanho aumentou 61,96%, com destaque para as regiões Sul (72,98%) e Sudeste (62,31%). A produção de leite foi mais correlacionada com o número de vacas ordenhadas (P<0,05; r=0,97) e com a produtividade por vaca (P<0,05; r=0,63), do que com a área dos estabelecimentos rurais (P<0,05; r=0,38). Conclui-se que mudanças importantes ocorreram na pecuária leiteira no intervalo de onze anos, incluindo mudanças na geografia da produção, maior concentração e profissionalização da atividade, além do expressivo crescimento da produção de leite em praticamente todos os estados, reflexo da maior produtividade do rebanho nacional.

In this study, we investigated the principal transformations in dairy farming among Brazilian federative units in the period from 2006 to 2017. Data were drawn from the Agricultural Censuses from 2006 and 2017. In order to compare the variations between the states and macroregions, descriptive analyses were performed. Pearson correlation was used to test the correlation among the variables. A 4.63% decrease was observed in the number of establishments supporting cattle, notably in the states of PE (-23.02%), RS (-20.67%) and PR (-19.65%). Some states showed greater participation in terms of increase in number of cattle, particularly in the Northern region. No significant change in pasture area was observed. A decrease of 12.92% in number of milk producers was observed, mainly in the traditional dairy basins, such as RS (-36.62%), PR (-27.33%), SP (-24.67%) and SC (-20.21%). Producers who continued in the activity had a rise in the scale of their daily production. Although there was a 9.47% reduction in the number of cows milked, the herd productivity showed a 61.96% surge, particularly in the Southern (72.98%) and South-eastern (62.31%) areas. Milk production revealed higher correlation with number of cows milked (P<0.05; r=0.97) and productivity per cow (P<0.05; r=0.63), than with area of the rural establishments (P<0.05; r=0.38). In conclusion, there were significant changes in dairy farming over an eleven-year period, including changes in the geography of production, greater concentration and professionalization of the activity, as well as the expressive growth of milk production in almost every state, which is reflective of higher productivity of the national herd.

RESUMEN

O termo potencial de produção representa a quantidade máxima de produto que seria possível se obter em uma determinada área. Mas qual é o potencial de produção da bovinocultura de corte em pastagens tropicais? Para responder esta pergunta, é necessário compreender os fatores relacionados ao acúmulo de forragem, eficiência de pastejo, composição química da planta forrageira, consumo de forragem e requerimento nutricional dos animais para um dado desempenho, manejo, genética e gestão do sistema de produção. A produtividade média anual da pecuária de corte no Brasil está em torno de 120 kg de peso corporal (aproximadamente 60 kg de carcaça) por hectare. Este índice está bem abaixo de resultados reportados na literatura. O manejo adequado de pastagens com forrageiras tropicais normalmente proporciona taxa de lotação acima de uma unidade animal (UA, 450 kg) por hectare. O aumento na taxa de lotação, combinado com elevado ganho de peso proporcionam alta produtividade, podendo ultrapassar 1260 kg de peso corporal (aproximadamente 630 kg de carcaça) anuais por hectare. A produção de bovinos de corte em pastagens tropicais possui alto potencial de resposta quanto a adoção de tecnologias para incremento nos índices de produtividade.

The expression production potential represents the maximum amount of products that can be obtained per unit area. However, what is the maximum amount of product that can be obtained in a pasture area? To answer this question, it is necessary to understand the factors related to forage accumulation, grazing efficiency, chemical composition of the forage plant, forage intake and nutritional requirements of animals, management, genetics, and management of the production system. The average annual productivity of beef cattle in Brazil is approximately 120 kg of body weight (approximately 60 kg of carcass) per hectare. This index is below the parameters reported in the literature. Adequate management of pastures with tropical forages usually provides a stocking rate above one animal unit (450 kg) per hectare. The increase in the stocking rate, combined with high individual body weight gain, provides high productivity, which may exceed 1260 kg of body weight (approximately 630 of carcass) per hectare per year. The production of beef cattle in tropical pastures has a high response potential with regard to the adoption of technologies to increase productivity indices.

RESUMEN

The objective of this study was to evaluate consumer habits as well as the sensory perception and characteristics of farm eggs produced in Los Ríos, Chile. Data were collected from an online survey of 197 respondents and a sensory evaluation carried out by 30 untrained panelists of 4 types of eggs (brown-shell and blue-shell eggs acquired from family farms, free-range eggs acquired from large, industrial systems, and white-shell cage eggs from industrial, cage systems.) To evaluate differences and preferences, data were analyzed in a GLM. In addition, sensory evaluation was analyzed using principal component analysis. In accordance with the survey, 99% of the participants eat eggs (P < 0.001), 58% eat 1 to 3 eggs/wk, and 84% declared to consume eggs at home (<0.0001). Surveyed participants reported that price and size are the determining factors (31%) when purchasing eggs. Among the physical characteristic for consumers, yolk color was the most important attribute rather than white color, egg appearance, texture, flavor, or odor. In the consumer acceptability test, farm eggs (either brown or blue shell) received the most favorable sensory evaluation by the panel and were preferred to both free-range and white-shell cage eggs. Yolk color was the most influential parameter in making this difference. Brown farm eggs were predominately selected for greatest general satisfaction by participants in both the sensory evaluation (P = 0.008) and in the survey (40%; P = 0.026). There were no differences between farm eggs (brown and blue shell, P > 0.05) in the evaluated parameters. There was a consequence in the information given from surveyed consumers and the sensory panel with the yolk color.

RESUMEN

RATIONALE/BACKGROUND: Though much smaller than the bovine industry, the porcine sector in Argentina involves a large number of farms and represents a significant economic sector. In recent years Argentina has implemented a national registry of swine movements amongst other measures, in an effort to control and eventually eradicate endemic Aujesky's disease. Such information can prove valuable in assessing the risk of transmission between farms for endemic diseases but also for other diseases at risk of emergence. METHODS: Shipment data from 2011 to 2016 were analyzed in an effort to define strategic locations and times at which control and surveillance efforts should be focused to provide cost-effective interventions. Social network analysis (SNA) was used to characterize the network as a whole and at the individual farm and market level to help identify important nodes. Spatio-temporal trends of pig movements were also analyzed. Finally, in an attempt to classify farms and markets in different groups based on their SNA metrics, we used factor analysis for mixed data (FAMD) and hierarchical clustering. RESULTS: The network involved approximate 136,000 shipments for a total of 6 million pigs. Over 350 markets and 17,800 production units participated in shipments with another 83,500 not participating. Temporal data of shipments and network metrics showed peaks in shipments in September and October. Most shipments where within provinces, with Buenos Aires, Cordoba and Santa Fe concentrating 61% of shipments. Network analysis showed that markets are involved in relatively few shipments but hold strategic positions with much higher betweenness compared to farms. Hierarchical clustering yielded four groups based on SNA metrics and node characteristics which can be broadly described as: 1. small and backyard farms; 2. industrial farms; 3. markets; and 4. a single outlying market with extreme centrality values. CONCLUSION: Characterizing the network structure and spatio-temporal characteristics of Argentine swine shipments provides valuable information that can guide targeted and more cost-effective surveillance and control programs. We located key nodes where efforts should be prioritized. Pig network characteristics and patterns can be used to create dynamic disease transmission models, which can both be used in assessing the impact of emerging diseases and guiding efforts to eradicate endemic ones.

RESUMEN

The goal of this research was to evaluate the microclimate (temperature, relative humidity and ECI-enthalpy comfort index) of commercial loads of broiler chickens at different transport distances: Dist15 (15 km on average) and Dist90 (90 km on average) in the summer and winter seasons and their effects on the production parameters body weight difference (BWD), mortality (%) and bruising prevalence (%). Twelve broiler loads were monitored using dataloggers to record temperature and humidity, with a total of 24 target crates per load. The experiment followed a factorial design [2 seasons (rainy and dry) × 2 distances (Dist15 and Dist90)] with a randomized complete block arrangement, 3 sexes (all males, all females, or mixed shipments) and one shipment per combination. BWD had a heterogeneous distribution throughout the load, and this distribution was not significantly correlated with the mean ECI measured during transport at 12 positions along the load. In terms of comfort, summer is the most critical period for broiler transport. In the interaction between rainy season and Dist90, the highest ECI was scored in the lethal zone (where physiological mechanisms are not enough to control body temperature). Mortality during the rainy season was not significantly different between distances. However, during the dry season, mortality was twice as high as broilers that travelled for 15 km. The prevalence of bruising on carcasses was not affected by the interaction between season and distance. As we know, broiler chicken performance, during transport, can be also related to road conditions, being hard to evaluate the real impact of seasons and distances on animal welfare. Load microclimate can compromise broiler chicken welfare during transport and it does not necessary reflect significant losses pre and post-slaughter.

RESUMEN

In human-transformed landscapes, predators may feed on domesticated animals, and thus affect human well-being, creating negative perceptions and leading to conflict with people that can result in the persecution of the predator. We studied the factors that influence the perception of the Black-and-chestnut Eagle (Spizaetus isidori) in four rural Andean communities in Colombia and compiled historical and recent evidence on the persecution and other causes of mortality of this species in the country. We applied 267 questionnaires and conducted 16 interviews with local inhabitants, via visits to homes and schools in the surroundings of S. isidori nests. The perception of S. isidori by the inhabitants was largely negative and influenced by different socio-demographic factors such as gender, chicken (Gallus gallus) ownership, and chicken management. The records we obtained indicate that 47 eagles were shot, 16 were captured (three for illegal trafficking) and two were electrocuted on high-tension wires. The persecution of S. isidori occurs as retaliation or as a preventative measure against chicken predation, and is a significant cause of mortality of this species in Colombia. Effective conservation planning for S. isidori in Colombia needs to go further than the protected areas system, and include a socioecological perspective in conservation practices applied at landscapes scales that are dominated by people. Education programs and socioecological research, along with participatory work in local communities are key to the conservation of S. isidori in breeding territories. This approach can also prevent conflict over food resources-G. gallus and other poultry-that are shared by humans and S. isidori in rural landscapes.

RESUMEN

Examining zebrafish populations for the presence of disease is an integral component of managing fish health in research facilities. Currently, many different strategies are used for zebrafish fish health inspections, which is a scenario that may result in subjective and biased diagnostic evaluations. The goal of this study was to compare the success of pathogen detection between a sample size of randomly selected fish (n = 60) that provides 95% confidence in pathogen detection based on a presumed pathogen prevalence level ≥5%, and other subpopulations and sample numbers commonly submitted for diagnostic testing within a 1000 tank, 30,000 fish, recirculating research system. This included fish collected from a sump tank (n = 53), sentinel fish (n = 11), and fish that were found moribund or freshly dead (n = 18). Additionally, five fish from each subpopulation were collected for histopathologic examination. A second study used retrospective data to examine pathogen distribution between systems (n = 2-5) in multi-system facilities (n = 5) using a sample size of 60 fish per system. For the pathogens detected, results supported the use of representative sample numbers rather than smaller numbers of populations considered more at risk. The exception to this is for the moribund/mortality group, which may be a resource for targeted surveillance of select pathogens. Each system within multi-system facilities should be considered separate units in terms of fish health inspections and biosecurity. Development of these evidence-based standards for fish health inspections in zebrafish systems enhances fish welfare, provides identification of potentially zoonotic pathogens, and ensures scientific integrity and reproducibility of research results.

RESUMEN

In order to assess the level of sheep welfare in small traditional farms as compared with farms of increased size we evaluated several animal-based parameters and applied a modified Animal Needs Index (ANI) protocol in farms located in the North-East of the country. We selected ten sheep farms: 5 farms had less than 20 ewes per flock (Group L20), whereas 5 farms had more than 20 ewes per flock (Group M20). Based on the recordings performed using the ANI scheme Group L20 constantly showed higher scores as compared with Group M20. In Group M20 a higher proportion of animals was affected by skin and wool damages, low body condition, tail mutilation, ocular discharge, nasal discharge, diarrhoea (P < 0.05) and lameness (P < 0.01). We observed a higher percentage of non-anaemic animals in group L20 and a higher percentage of anaemic animals in Group M20 (P < 0.01). Although based on a small sample, our results showed that several animal-based measures were able to discriminate the two groups of farms with higher levels of animal welfare detected in small flocks.

RESUMEN

This study uses network analysis to evaluate how swine movements in Argentina could contribute to disease spread. Movement data for the 2014-2017 period were obtained from Argentina's online livestock traceability registry and categorized as follows: animals of high genetic value sent to other farms, animals to or from markets, animals sent to finisher operations and slaughterhouse. A network analysis was carried out considering the first three movement types. First, descriptive, centrality and cohesion measures were calculated for each movement type and year. Next, to determine whether networks had a small-world topology, these were compared with the results from random Erdös-Rényi network simulations. Then, the basic reproductive number (R0 ) of the genetic network, the group of farms with higher potential for disease spread standing at the top of the production chain, was calculated to identify farms acting as super-spreaders. Finally, their external biosecurity scores were evaluated. The genetic network in Argentina presented a scale-free and small-world topology. Thus, we estimate that disease spread would be fast, preferably to highly connected nodes and with little chances of being contained. Throughout the study, 31 farms were identified as super-spreaders in the genetic network for all years, while other 55 were super-spreaders at least once, from an average of 1,613 farms per year. Interestingly, removal of less than 5% of higher degree and betweenness farms resulted in a >90% reduction of R0 indicating that few farms have a key role in disease spread. When biosecurity scores of the most relevant super-spreaders were examined, it was evident that many were at risk of introducing and disseminating new pathogens across the whole of Argentina's pig production network. These results highlight the usefulness of establishing targeted surveillance and intervention programmes, emphasizing the need for better biosecurity scores in Argentinean swine production units, especially in super-spreader farms.

RESUMEN

This study aimed to evaluate the production parameters of herds in 100 dairy family farms in the mesoregion of the Acre Valley, in Western Amazon, Brazil. To this end, the farms were divided into two levels of milk production. Data were collected from March to June 2016, using a 248-question semi structured form and on-site observations. The information was recorded in SPSS® spreadsheets. Dairy farmers were divided into two clusters known as "high production cluster" (1,755.65 L ha-¹ yr-¹) and "low production cluster" (492.75 L ha-¹ yr-¹), using the K-means non-hierarchical method. Descriptive statistics was used and, with the aid of the multivariate cluster analysis, cattle ranchers were divided into the two clusters (high and low production). The results showed that the high-production cluster had larger total milk production (L milk cow-¹ day-¹) and family income within smaller areas and using less workforce. The farmers in this group also used more ear tags for cattle identification and more technologies such as electric fence and artificial insemination at a fixed time. We concluded that family farms should improve their management and receive technical assistance to strengthen their weaknesses in dairy-cow health and reproduction systems. Moreover, milk yield in these dairy farms should be improved to increase profitability of farmers.

O objetivo deste estudo foi analisar 100 fazendas leiteiras sob regime de agricultura familiar a partir da mesorregião do Vale do Acre, na Amazônia Ocidental, Brasil. considerando alguns aspectos dos rebanhos, considerando diferentes níveis de produção de leite. Os dados foram coletados no período de março a junho de 2016, a partir de um formulário semiestruturado, contendo 248 questões, por meio de observação in loco, bem como as respostas obtidas com os proprietários; e gravados em planilhas SPSS®. Os produtores de leite foram divididos em agrupamentos denominados "maior produtividade" (1.755,65 litro/hectare/ano) e "menor produtividade" (492,75 litros / hectare / ano) utilizando o método não-hierárquico K-means. Adotou-se a estatística descritiva e, com o auxílio da metodologia de análise multivariada de clusters, os pecuaristas foram divididos em dois agrupamentos com diferentes características em termos de produtividade (maior e menor). Algumas diferenças relevantes entre as propriedades foram identificadas: aquelas pertencentes ao cluster de maior produtividade aumentaram a produção total de leite, leite/vaca/dia e renda familiar, e utilizaram menor área e força de trabalho para produção. Essas propriedades também mostraram maior uso de brincos para identificação e utilizaram mais tecnologias, como cerca elétrica e inseminação artificial em tempo fixo. Concluímos que é necessário melhorar a gestão das propriedades familiares e tomar medidas de assistência técnica para corrigir os pontos fracos na saúde e reprodução das vacas leiteiras. Além disso, é essencial melhorar a produtividade para aumentar a lucratividade das fazendas leiteiras rurais.

To this end, the farms were divided into two levels of milk production. Data were collected from March to June 2016, using a 248-question semi structured form and on-site observations. The information was recorded in SPSS® spreadsheets. Dairy farmers were divided into two clusters known as "high production cluster" (1,755.65 L ha-¹ yr-¹) and "low production cluster" (492.75 L ha-¹ yr-¹), using the K-means non-hierarchical method. Descriptive statistics was used and, with the aid of the multivariate cluster analysis, cattle ranchers were divided into the two clusters (high and low production). The results showed that the high-production cluster had larger total milk production (L milk cow-¹ day-¹) and family income within smaller areas and using less workforce. The farmers in this group also used more ear tags for cattle identification and more technologies such as electric fence and artificial insemination at a fixed time. We concluded that family farms should improve their management and receive technical assistance to strengthen their weaknesses in dairy-cow health and reproduction systems. Moreover, milk yield in these dairy farms should be improved to increase profitability of farmers.(AU)

O objetivo deste estudo foi analisar 100 fazendas leiteiras sob regime de agricultura familiar a partir da mesorregião do Vale do Acre, na Amazônia Ocidental, Brasil. considerando alguns aspectos dos rebanhos, considerando diferentes níveis de produção de leite. Os dados foram coletados no período de março a junho de 2016, a partir de um formulário semiestruturado, contendo 248 questões, por meio de observação in loco, bem como as respostas obtidas com os proprietários; e gravados em planilhas SPSS®. Os produtores de leite foram divididos em agrupamentos denominados "maior produtividade" (1.755,65 litro/hectare/ano) e "menor produtividade" (492,75 litros / hectare / ano) utilizando o método não-hierárquico K-means. Adotou-se a estatística descritiva e, com o auxílio da metodologia de análise multivariada de clusters, os pecuaristas foram divididos em dois agrupamentos com diferentes características em termos de produtividade (maior e menor). Algumas diferenças relevantes entre as propriedades foram identificadas: aquelas pertencentes ao cluster de maior produtividade aumentaram a produção total de leite, leite/vaca/dia e renda familiar, e utilizaram menor área e força de trabalho para produção. Essas propriedades também mostraram maior uso de brincos para identificação e utilizaram mais tecnologias, como cerca elétrica e inseminação artificial em tempo fixo. Concluímos que é necessário melhorar a gestão das propriedades familiares e tomar medidas de assistência técnica para corrigir os pontos fracos na saúde e reprodução das vacas leiteiras. Além disso, é essencial melhorar a produtividade para aumentar a lucratividade das fazendas leiteiras rurais.(AU)

RESUMEN

The objective of this study was to map public policies for population management of dogs and cats in the Curitiba Metropolitan Region (CMR) and to assess their correlations with social indicators. The data used consisted of answers from questionnaires sent via email to public managers of 14 municipalities of the CMR, and data from the Brazilian Institute of Geography and Statistics (IBGE) and Parana Institute for Economic and Social Development (IPARDES). Nine of the 14 municipalities (64.29%) had public policies for population management of dogs and cats, and five (35.71%) had no such public policies. Six (42.86%) municipalities had no other public policy related to population management of dogs and cats, besides population management; and eight (57.14%) had other public policies. The three indicators that had significant and positive correlation with the existence of these public policies were Total Gross Domestic Product (GDPt) (0.028), Income Inequality (GINI index) (0.039), and Human Development Index (HDI) (0.039). However, the decision for the implementation of public policies related to animals depends on the local government because investments on these policies are not considered in the municipal tax revenue.

O objetivo deste estudo foi mapear políticas públicas para manejo populacional de cães e gatos na Região Metropolitana de Curitiba (RMC) e avaliar suas correlações com indicadores sociais. Os dados utilizados foram respostas de questionários enviados por e-mail a gestores públicos de 14 municípios da RMC e dados do Instituto Brasileiro de Geografia e Estatística (IBGE) e Instituto Paranaense de Desenvolvimento Econômico e Social (IPARDES). Nove dos 14 municípios (64,29%) possuíam políticas públicas para o manejo populacional de cães e gatos e cinco (35,71%) não possuíam tais políticas públicas. Seis (42,86%) municípios não possuíam outras políticas públicas relacionadas ao manejo populacional de cães e gatos, além do manejo populacional; e oito (57,14%) possuíam outras políticas públicas. Os três indicadores que apresentaram correlação significativa e positiva com a existência dessas políticas públicas foram Produto Interno Bruto Total (PIBt) (0,028), Desigualdade de Renda (índice GINI) (0,039) e Índice de Desenvolvimento Humano (IDH) (0,039). No entanto, a decisão para a implementação de políticas públicas relacionadas a animais depende do governo local, pois os investimentos nessas políticas não são considerados na receita tributária municipal.

RESUMEN

The objective of this study was to evaluate the technological level and productive performance of the milk producing units of the municipality of Rondon do Pará in the state of Pará. Data were collected through interviews with questionnaires, conducted at 55 dairy farms, which accounted for 43.3% of the milked cows in the municipality. The factors that characterize the systems of bovine milk production were estimated by means of factorial analysis using 12 variables representative of the production units surveyed. Five factors were extracted: F1 = size of the enterprise; F2 = environment and nutrition; F3 = technical assistance and herd management; F4 = animal health; F5 = schooling. From the scores associated with each factor, the index for productive performance of dairy cattle (DFPI) was calculated. The properties were classified into three levels of productive performance, including two considered to have a high level of DFPI, 16 with intermediate productive performance and 37 considered to have a low level of DFPI. There is a need to adopt technologies that promote the productive performance of dairy cattle in Rondon do Pará, as well as enable adaptation to socio-environmental public policies, with the aim of strengthening sustainable rural production through strategic actions that facilitate an increased technological level in farming systems production.

Avalia-se o nível tecnológico e o desempenho produtivo das unidades produtoras de leite do município de Rondon do Pará, estado do Pará. Os dados foram coletados a partir de entrevistas, com utilização de questionários, realizadas em 55 propriedades leiteiras, que juntas representam 43,3% do plantel de vacas ordenhadas do município. Os fatores que caracterizam os sistemas de produção de leite bovino foram estimados por meio de análise fatorial, utilizando 12 variáveis representativas das unidades de produção pesquisadas. Foram extraídos cinco fatores: F1 = tamanho do empreendimento; F2 = meio ambiente e nutrição; F3 = assistência técnica e manejo do rebanho; F4 = sanidade animal; e F5 = escolaridade. A partir dos escores associados a cada fator foi calculado o índice de desempenho produtivo da pecuária leiteira (IDPL). As propriedades foram classificadas em três níveis de desempenho produtivo, entre elas, duas consideradas com nível alto de IDPL, 16 com desempenho produtivo intermediário e 37 consideradas de nível baixo. Há necessidade da adoção de tecnologias para promover o desempenho produtivo da pecuária leiteira de Rondon do Pará, bem como possibilitar adequação às políticas públicas socioambientais, visando fortalecer a produção rural sustentável, por meio de ações estratégicas que viabilizem o aumento do nível tecnológico dos sistemas de produção.
