RESUMEN
This research aimed for the first time to identify the essential welfare problems on 46 goat dairy farms in Vojvodina,based on the goat AWIN welfare protocol. The study showed that space allowance per goat was 1.55, 1.86 and 2.50 m2/goat (large, medium, small-sized farms, respectively). Most farms possessed the soil floor and straw as a flooring material. The small and medium farms more allowed access to the outdoor area. Contrary, large-sized farms mostly kept goats in fully housed systems with reduced opportunities for the goats to express their natural behavior. Management procedures were significantly different (p < 0.05) between the investigated farms. Differences were mainly in bedding, feeding and culling strategies. Low productivity was the main cause of culling in all farm types. Small-sized farms carried out more often disbudding (42.9%) in comparison with medium (21.4%) and large-sized ones (14.3%). Group level observation showed that the main areas of concern were associated with hair coat condition and kneeling at the feeding rack (p < 0.05). Inadequate BCS, udder asymmetry and claw overgrowth were frequently recorded. The prevalence of thin and fat goats was highest in large-sized farms All farm size categories and management systems showed certain welfare weaknesses. Thus, the findings highlighted the need for higher implementation of animal welfare principles and improvement of management techniques to meet the welfare requirements of dairy goats.
RESUMEN
We address the hypothesis that keeping kids and mothers together would have positive effects on the milk composition of the mother and the behaviour of the kids. Kids were either permanently separated (SEP), daily separated between 7.30 and 15 h (DAY-SEP) or kept with mothers 24 h/d (NON-SEP). The NON-SEP kids were only allowed to suckle one teat. All kids had similar growth rate throughout the study (lactation days 5-70). DAY-SEP kids spent 24% of their time with their mother at both ages. NON-SEP spent only 15% of the time with their mothers at 2 weeks of age and this increased to 28% at 2 months of age. NON-SEP kids showed more hiding behaviour at 2 weeks and SEP were more active alone, at both 2 weeks and 2 months, compared to the other treatments. The mean available milk yield and fat concentration were higher in DAY-SEP goats (2420 g ± 119 g and 4.9 ± 0.1%) compared with NON-SEP goats (2149 ± 79 g and 4.4 ± 0.1%). There were no differences between DAY-SEP and NON-SEP goats in total protein, lactose, or casein concentrations. Based on these data it was estimated that 7.1 kg milk was needed to produce 1 kg semi-hard cheese in DAY-SEP goats and 7.5 kg in NON-SEP goats, respectively. When comparing milk yield and composition between udder halves, the milk yield was, as expected, higher from the machine milked teat than from the suckled one in the NON-SEP goats but there was no difference between right and left udder halves in DAY-SEP goats. Milk fat concentration varied between teats at morning and afternoon milkings in NON-SEP goats, but there was no difference in milk fat between udder-halves in DAY-SEP goats. In conclusion, the kid growth rate was similar in all treatments, however, an altered behaviour was seen in permanently separated kids (SEP). The results show that it is possible to have a high milk yield and fat concentration with one kid together with the dam.

The objective of this study was to apply a modified AWIN Goat protocol to evaluate and compare the welfare of adult lactating and non-lactating dairy goats at pen and individual levels on small farms located in Ceará, Northeast, Brazil, and to take into consideration the application of this protocol on Brazilian Northeast goat farms. Five farms with Lactating goats (L) and five farms with non-lactating goats (NL) were evaluated. At the first level of welfare assessment, animals were evaluated in the pen and during the second level of welfare assessment, animals were evaluated in the pen and individually. Indicators assessed were animal and resource-based indicators. Significant difference between L and NL on farms was set at P<0.05. Only queuing at feeding indicator showed significant difference (P=0.027) between groups in pens at the first level welfare assessment. On individual assessments, there was significant difference between L and NL regarding body condition score (P=0.003), overgrown claws (P=0.001) and udder asymmetry (P=0.001). The application of a modified AWIN Goat protocol on farms in Ceará was considered positive. In general, these results demonstrated that both groups are submitted to welfare problems in Ceará, although lactating goats present more challenges to cope.(AU)
O objetivo deste estudo foi aplicar o protocolo AWIN de Cabras modificado para avaliar e comparar o bem-estar de cabras adultas lactantes e não lactantes em termos de baia e individualmente, em pequenas propriedades localizadas no Ceará, nordeste, Brasil, e levar em consideração a aplicação desse protocolo em fazendas caprinas do nordeste brasileiro. Cinco fazendas com cabras lactantes (L) e cinco fazendas com cabras não lactantes (NL) foram avaliadas. No primeiro nível de bem-estar, os animais foram avaliados nas baias e, durante o segundo nível de bem-estar, os animais foram avaliados na baia e individualmente. Os indicadores avaliados foram baseados em animais e recursos. Diferença significativa entre L e NL nas fazendas foi estabelecida em P<0,05. Apenas o indicador na fila na alimentação mostrou diferença significativa (P=0,027) entre os grupos na baia no primeiro nível de bem-estar. Nas avaliações individuais, houve diferença significativa entre L e NL com relação ao escore de condição corporal (P=0,003), sobrecrescimento das unhas (P=0,001) e assimetria do úbere (P=0,001). A aplicação do protocolo AWIN de cabras modificado em fazendas no Ceará foi considerada positiva. De modo geral, esses resultados demonstraram que ambos os grupos estão submetidos a problemas de bem-estar no Ceará, embora cabras em lactação apresentem mais desafios para enfrentar.(AU)

The Norwegian dairy goat industry has largely succeeded in controlling caprine arthritis encephalitis (CAE), caseous lymphadenitis (CLA) and paratuberculosis through a voluntary disease eradication programme called Healthier Goats (HG). The aim of this study was to apply an on-farm welfare assessment protocol to assess the effects of HG on goat welfare. A total of 30 dairy goat farms were visited, of which 15 had completed disease eradication and 15 had not yet started. Three trained observers assessed the welfare on 10 farms each. The welfare assessment protocol comprised both resource-based and animal-based welfare measures, including a preliminary version of qualitative behavioural assessments with five prefixed terms. A total of 20 goats in each herd were randomly selected for observations of human-animal interactions and physical health. The latter included registering abnormalities of eyes, nostrils, ears, skin, lymph nodes, joints, udder, claws and body condition score. For individual-level data, robust clustered logistic regression analyses with farm as cluster variable were conducted to assess the association with disease eradication. Wilcoxon rank-sum tests were used for comparisons of herd-level data between the two groups. Goats with swollen joints (indicative of CAE) and enlarged lymph nodes (indicative of CLA) were registered on 53% and 93% of the non-HG farms, respectively, but on none of the HG farms. The only other health variables with significantly lower levels in HG herds were skin lesions (P=0.008) and damaged ears due to torn out ear tags (P<0.001). Goats on HG farms showed less fear of unknown humans (P=0.013), and the qualitative behavioural assessments indicated that the animals in these herds were calmer than in non-HG herds. Significantly more space and lower gas concentrations reflected the upgrading of buildings usually done on HG farms. In conclusion, HG has resulted in some welfare improvements beyond the elimination of infectious diseases. The protocol was considered a useful tool to evaluate the welfare consequences of a disease eradication programme. However, larger sample sizes would increase the reliability of prevalence estimates for less common conditions and increase the power to detect differences between the groups. Despite the obvious link between disease and suffering, this aspect is rarely taken into account in the evaluation of disease control programmes. We therefore propose that welfare assessment protocols should be applied to evaluate the merits of disease control or eradication programmes in terms of animal welfare.
