RESUMEN
The use of agroindustrial by-products, such as dried distillers grains with solubles (DDGS) and dried citrus pulp (DCP), has been widely investigated in dairy cows, but information on their effects in dairy goats is limited. The influence of feeding olive cake (a by-product of olive oil production) to dairy goats has been assessed in some studies, but exhausted olive cake (EOC) has been much less investigated. Twelve Murciano-Granadina goats were used in a crossover design trial with 2 periods to assess the effects of including agroindustrial by-products on nutrient digestibility, ruminal fermentation, methane production, urinary excretion of purine derivatives, and milk yield and composition. In each period, 6 goats received daily a control diet comprising 1 kg of alfalfa hay and 1 kg of high-cereal concentrate, and another 6 goats received a diet (BYP) comprising 1 kg of alfalfa hay and 1 kg of a concentrate including corn DDGS, DCP, and EOC in proportions of 180, 180, and 80 g/kg of concentrate (as-fed basis), respectively. Diet had no effect on total dry matter intake, but intake of alfalfa hay, CP, and fat was greater for the BYP group than for the control group. There were no differences between diets in nutrient apparent digestibility, with the exception of fat, which was greater for the BYP diet compared with the control diet. Although fecal N tended to be greater for the BYP diet, there were no differences in N utilization. Compared with the control diet, milk yield tended to be greater and daily production of milk CP, fat, whey protein, and TS as well as milk gross energy were greater for the BYP diet. The concentration of C12:0, C14:0, and C16:0 fatty acids (FA) was or tended to be lower and the concentration of polyunsaturated FA was greater in the milk of BYP-fed goats compared with goats fed the control diet. Diet had no effect on ruminal parameters (pH, volatile FA, and NH3-N concentrations) and methane emissions, but urinary excretion of total purine derivatives tended to be lower in BYP-fed goats than in those fed the control diet. A mixture of corn DDGS (180 g), DCP (180 g), and EOC (80 g) could replace 44% of cereal grains and protein feeds in the concentrate for dairy goats without compromising nutrient utilization, ruminal fermentation, or milk yield and led to a more unsaturated FA profile in milk.

Intensive dairy goat production in the Mediterranean basin is based on imported conventional ingredients to be included in concentrates. Fourteen Murciano-Granadina goats in the middle of the third lactation were allocated into 2 groups of 7 animals each fed, respectively, a control diet based on alfalfa hay and concentrate in a 40:60 ratio, and a diet in which the concentrate included tomato fruits, citrus pulp, brewer's grain and brewer's yeast (T100CBY) to study the effect of diet on nutrient utilization, ruminal fermentation, purine derivatives excretion in urine, milk yield and composition, and methane emissions. No effect of the diet on total dry matter intake was observed. Digestibility of neutral detergent fiber and acid detergent fiber were higher for T100CBY compared with the control diet. The N in feces and urine was lower and balance and retained N were higher in animals fed T100CBY than the control diet. Milk protein N and energy were similar for both diets. Metabolizable energy per energy intake and metabolizable energy per digestible energy were higher and energy in methane was lower with diet T100CBY than with the control. Milk yield and composition were not affected by diet, with the exception of protein, casein, and total solids, which were higher for diet T100CBY than the control. Diet T100CBY promoted less saturated fatty acids and higher mono- and polyunsaturated fatty acids in milk than the control diet. Diet T100CBY produced less methane and NH3 concentration in the rumen, higher propionate, and a lower acetate-to-propionate ratio without an effect on the volatile fatty acid concentration. The concentrate with by-products did not affect urinary excretion of total purine derivatives, reduced feeding costs, and increased profit margin by 14 and 16% compared with the control. The mixture of tomato fruits, citrus pulp, brewer's grain, and brewer's yeast could replace 47% of conventional ingredients (corn, wheat bran, sunflower meal, and soy flour) in the concentrate of the dairy goat diet, reducing feeding cost and methane production, leading to a healthier fatty acids profile in milk without compromising nutrient utilization or milk yield.

Microbiological analyses were conducted on wild eels from the L'Albufera Lake (Spain). A total of 174 individuals were collected in two surveys (i.e. year 2008 and autumn-winter 2014) among those caught by local fishermen into the lagoon. The prevalence of Shewanella putrefaciens group was 1.7% in 2008 and rose above 32% in 2014. It was due to an outbreak of shewanellosis that presented a morbidity rate of 64%. S. putrefaciens group strains were isolated as pure cultures from the sick eels that showed white ulcers surrounded by a reddish inflammation, damage of the mouth, extensive skin discoloration, exophthalmia, ascites and bad odour. The S. putrefaciens group was recovered from freshwater samples taken at the L'Albufera system, along autumn-winter 2015. Its counts significantly increased in freshwater parallel to hypoxia and temperature rising. Shewanellae strains were identified as S. putrefaciens and S. xiamenensis by 16S rRNA gene sequencing. These isolates recovered from sick eels or freshwater were virulent for European eel by IP challenge (LD50 106 CFU g-1 body weight). They also caused 30-38% cumulative mortality, in European eels challenged by a 2-h bath (107 CFU mL-1 ). These results suggest that shewanellosis could be transmitted through water highlighting the fact that hypoxic conditions increase this bacterium levels in water.

Objetivo: Las infecciones del tracto urinario (ITU) suelen manejarse ambulatoriamente. Sin embargo, un pequeño porcentaje requiere ingreso hospitalario. Nuestro objetivo fue analizar los factores de riesgo y características microbiológicas de las infecciones urinarias adquiridas en la comunidad (ITU-AC) que requieren hospitalización. Material y métodos: Realizamos un estudio prospectivo desde noviembre de 2011 a diciembre de 2013 evaluando la incidencia, factores de riesgo, patrones microbiológicos y tasas de resistencia en los pacientes con ITU-AC que requieren ingreso. Resultados: Cuatrocientos cincuenta y siete pacientes ingresaron en nuestro servicio con diagnóstico de ITU-AC. La edad media fue 56,2 ± 19,85 años, el 52,1% eran mujeres, el 19,7% portaban catéter urinario y el 11,4% habían presentado ITU en los meses previos. Los microorganismos más frecuentemente aislados fueron Escherichia coli (60,6%), Klebsiella (9,2%), Enterococcus (8,4%) y Pseudomonas (7,2%). Enterobacteriaceae diferentes a E. coli fueron más frecuentes en pacientes de mayor edad. Enterococcus fueron más frecuentemente aislados en pacientes que habían tenido ITU previa y en aquellos portadores de catéter urinario. E. coli mostró unas resistencias del 23,5% para amoxicilina/ácido clavulánico, 16,6% para cefalosporinas de tercera generación, 31,3% para quinolonas y16,7% para aminoglucósidos. Del total de E. coli 11,4% fueron productores de betalactamasas de espectro extendido (BLEE). Los Enterococcus y Pseudomonas mostraron resistencias a quinolonas del 50,0% y 61,5% respectivamente. Conclusiones: ITU-AC que requieren hospitalización se presentan más frecuentemente en varones de mayor edad, portadores de catéter urinario, litiasis urinaria y con episodios previos de ITU. Estos factores también se asocian con infecciones producidas por gérmenes diferentes a E. coli y altas tasas de resistencia
Objective: Although patients with urinary tract infections (UTIs) are usually managed as outpatients, a percentage of them requires hospitalization. To review risk factors and microbiological characteristics of community-associated UTIs (CAUTIs) requiring hospitalization has been our objective. Material and methods: A prospective observational study was carried out from November 2011 to December 2013. Incidence, microbiological characteristics and antibiotic resistance patterns in patients with CAUTIs that required hospitalization were analyzed. Risk factors (including diabetes mellitus, urolithiasis, urinary catheterization) and resistance rates of each pathogen were also analyzed. Results: Four hundred and fifty seven patients were hospitalized in our department with CAUTI. The mean age was 56.2 ± 19.85 years. Of them, 52.1% patients were women, 19.7% had urinary indwelling catheter and 11.4% have had a previous UTI. The most frequently isolated pathogens were Escherichia coli (60.6%), followed by Klebsiella (9.2%), Enterococcus (8.4%) and Pseudomonas (7.2%). Enterobacteriaceae other than E.coli were more prevalent in male and older patients. On the other side the most frequently isolated pathogen in patients with a previous UTI and a urinary catheter was Entercoccus. The resistance rates E. coli against ampicillin/amoxicillin + βlactamase inhibitor was 23.5%, against third-generation cephalosporins 16.6%, against fluoroquinolones 31.3% and 16.7% against aminoglycosides. 11.4% E. coli strains were producers of extended-spectrum Beta-lactamases (ESBL). Finally, the resistance rates of Enterococcus and Pseudomonas against quinolones were of 50.0% and 61.5%, respectively. Conclusions: CAUTIs that require hospitalization are most frequent in older age, male gender, and presence of urinary catheter, with urolithiasis and with previous episodes of UTI. These factors are also related to isolation of pathogens other than E. coli and higher resistance rates

Aeromonas infections are rare in Europe and often related to traveller's diarrhoea. A total of 185 Aeromonas isolates from river water, fish and clinical sources, recovered during a 1-year period, were used to investigate the disease spectrum and impact of multidrug-resistant (MDR) strains. They were all identified by biochemical tests and 25% of them were also identified by sequencing of the 16S rRNA gene. The minimum inhibitory concentrations (MICs) of 21 antimicrobials were determined for all isolates by broth microdilution/E-strips methods, and susceptibility was assessed according to the Clinical and Laboratory Standards Institute (CLSI). Strains pathogenicity was determined by using Swiss Webster mice as the animal model. Aeromonas diseases had an incidence of around 20 cases/million inhabitants in the metropolitan area of Valencia (Spain). Acute gastroenteritis in children with no history of travel abroad was the main pathology. These cases were related to A. caviae, A. veronii biovar sobria, A. hydrophila and A. dhakensis. A significant incidence of A. caviae in humans was found, while the other species were equally present in clinical and environmental origins. A. jandaei, A. bestiarum and A. media had mainly an environmental distribution. The prevalence of MDR Aeromonas was maximal in clinical samples, and resistance phenotypes were significantly related to this source. 7.2% of environmental Aeromonas was resistant to at least five drugs; most of them were moderately virulent for mice and, in addition, belonged to clinically significant species. The present study demonstrates a diseases spectrum similar to that reported in tropical countries, and also that pathogenic and heavily MDR Aeromonas are present in environmental reservoirs. MDR Aeromonas from any source analysed were susceptible to aztreonam, netilmicin, cefotaxime, ceftazidime, cefepime and fluoroquinolones.

Introducción y objetivo: Recientemente se vuelve a discutir sobre la implantación de la biopsia renal percutánea como procedimiento rutinario en el diagnóstico de masas renales. Sin embargo, aunque infrecuentes, esta técnica no está exenta de complicaciones y morbilidad. Nuestro objetivo es realizar un estudio descriptivo de las complicaciones y resultados de las biopsias renales ortotópicas con aguja de 16 G. Material y métodos: Llevamos a cabo una revisión retrospectiva de 180 biopsias renales ortotópicas ecodirigidas realizadas en nuestro servicio entre enero de 2008 y mayo de 2010. La técnica se realiza utilizando una aguja de diámetro 16 G acoplada a una pistola automática. Se recogen múltiples variables clínicas, así como las complicaciones tempranas derivadas del procedimiento y la actitud adoptada respecto a ellas. Se estudió la tasa de complicaciones, así como la relación entre factores de riesgo y aparición de complicaciones. Resultados: La edad media fue de 55,8 años, obteniéndose una media de 2,49 cilindros por intervención. La tasa global de complicaciones fue del 5,6%. Únicamente en 3 (1,67%) pacientes de los 180 fue necesaria una actitud intervencionista derivada de complicación del procedimiento. No hubo necesidad de intervenciones quirúrgicas ni se produjeron fallecimientos derivados del procedimiento. No se demostró relación entre HTA (p = 0,09), anticoagulación previa (p = 0,099) o antiagregación previa (p = 0,603) y complicaciones. El 2,8% de las biopsias presentaron material insuficiente para el diagnóstico. Conclusiones: La biopsia renal percutánea ecodirigida con aguja de 16 G es una técnica segura y con una rentabilidad diagnóstica elevada
Introduction and objective: The development of percutaneous renal biopsy as a routinary diagnostic procedure for renal masses is topic of discussion for the last few years. However, this technique has been associated with some complications, although infrequent, and morbidity. Our objective is to carry out a descriptive study about complications and outcomes of orthotopic kidney biopsies with 16 G needle. Material and methods: A retrospective review of 180 orthotopic ultrasound-guided renal biopsies performed in our service among January 2008 to May 2010 was carried out. The procedure was developed using an automated biopsy gun (16G needle). Multiple clinical variables, early post-procedure complications and its management were collected. Complication rates as well as the relationship between risk factors and occurrence of complications were studied. Results: Mean age was 55.8 years. The average number of biopsy cylinders per intervention was 2.49. The overall complication rate was 5.6%. An interventionist attitude derived from complication of the procedure was necessary in only 3 patients (1.67%). No surgical interventions were required and no death as consequence of procedure was registered. No relationship between hypertension (P = .09) previous anticoagulation (P = .099) or previous antiaggregation (P = .603) and complications were demonstrated. In 2.8% of biopsies the material obtained was insufficient for diagnosing. Conclusions: Percutaneous ultrasound-guided renal biopsy with 16G needle is a safe technique with high diagnostic performance

Caso clínico: Mujer de 25 años de edad que refería una tumoración no dolorosa amarillenta en el ojo derecho. Su agudeza visual era de la unidad. En la exploración en lámpara de hendidura se observa una masa amarilla-anaranjada localizada en el limbo superior del ojo derecho. No se observaron otras anormalidades. Discusión: Se realizó una escisión quirúrgica de la lesión y se remitió a anatomía patológica para su examen. La lesión granulomatosa mostraba células de Touton. Este hecho sugiere de forma importante el diagnóstico de xantogranuloma juvenil (JXG). La afectación ocular ocurre en el 10% de los casos de JXG (AU)
Case report: A 25-year-old woman noticed a painless yellow-orange mass on her right eye. Her visual acuity was 20/20 in both eyes, and a slit-lamp examination showed a yellow-orange mass located at the superior limbus of the right eye. No other ocular abnormalities were observed. Discussion: Surgical excision was carried out and the lesion was sent for histological examination. This showed a granulomatous lesion, rich in Touton-type giant cells, features that are strongly suggestive of juvenile xanthogranuloma (JXG). Ocular involvement occurs in 10% of cases of JXG (AU)

A virological analysis was conducted on wild eels from the Albufera Lake (Spain). A total of 179 individuals at different growth stages were collected in two different surveys (2004 and 2008). Presence of anguillid herpesvirus (AngHV-1), aquabirnavirus and betanodavirus was confirmed by PCR procedures in both surveys, although the number of detections was clearly higher in 2008 (83% of the eels analysed resulted positive for virus presence). AngHV-1 was the viral agent most frequently detected, followed by aquabirnaviruses. Betanodaviruses were detected by the first time in wild eels, and although the detections were only made by nested PCR, high percentage of positives were achieved. In addition, in 2008, seven aquabirnaviruses were isolated. Phylogenetic analysis performed using partial sequences of both genomic segments of aquabirnaviruses indicated that the seven isolates could be typed as WB (genogroup I) on the basis of segment A sequences, but when segment B was used six of them clustered with C1 strain (genogroup V) and one was typed as Ab (genogroup II). These results indicate natural reassortment between different strains of aquabirnaviruses in the eels. Although betanodaviruses were not isolated in cell culture, the analysis of the sequence of the nested PCR product indicated that they clustered with SJNNV genotype. The diversity of viral agents and the high level of viral detections suggest that viral infections may play a more prominent role in the decline of the European eel than initially thought.

The aim of this work was to investigate the effect of feeding ethyl-3-nitrooxy propionate (E3NP) and 3-nitrooxypropanol (3 NP), 2 recently developed compounds with potential antimethanogenic activity, in vitro and in vivo in nonlactating sheep on ruminal methane production, fermentation pattern, the abundance of major microbial groups, and feed degradability. Three experiments were conducted, 1 in vitro and 2 in vivo. The in vitro batch culture trial (experiment 1) tested 2 doses of E3NP and 3 NP (40 and 80 µL/L), which showed a substantial reduction of methane production (up to 95%) without affecting concentration of volatile fatty acids (VFA). The 2 in vivo trials were conducted over 16 d (experiment 2) and 30 d (experiment 3) to study their effects in sheep. In experiment 2, 6 adult nonpregnant sheep, with permanent rumen cannula and fed alfalfa hay and oats (60:40), were treated with E3NP at 2 doses (50 and 500 mg/animal per day). After 7, 14, and 15 d of treatment, methane emissions were recorded in respiration chambers and rumen fluid samples were collected for VFA analysis and quantification of bacterial, protozoal, and archaeal numbers by real-time PCR. Methane production decreased by 29% compared with the control with the higher dose of E3NP on d 14 to 15. A decrease in the acetate:propionate ratio was observed without detrimental effects on dry matter intake. In experiment 3, 9 adult nonpregnant sheep, with permanent rumen cannula and fed with alfalfa hay and oats (60:40), were treated with E3NP or 3 NP at one dose (100mg/animal per day) over 30 d. On d 14 and d 29 to 30, methane emissions were recorded in respiration chambers. Rumen fluid samples were collected on d 29 and 30 for VFA analysis and quantification of bacterial, protozoal, and archaeal numbers by real-time PCR. In addition, on d 22 and 23, samples of oats and alfalfa hay were incubated in the rumen of sheep to determine dry matter ruminal degradation over 24 and 48 h, respectively; no effect was observed (78.6, 78.3, and 78.8% of alfalfa and 74.2, 74.0, and 70.6% of oats in control, E3NP, and 3 NP groups, respectively). A reduction in methane production was observed for both additives at d 14 and d 29 to 30. In both treatments, the acetate:propionate ratio was significantly decreased. Likewise, total concentrations of the analyzed microbial groups in the rumen showed no difference among treatments and doses for both experiments. Both tested compounds showed promise as methane inhibitors in the rumen, with no detrimental effects on fermentation or intake, which would need to be confirmed in lactating animals.

Objetivo: Determinar las variables que influyen en la calidad de vida de pacientes tratados mediante cistectomía radical y conducto ileal. Material y método: Analizamos la calidad de vida utilizando el cuestionario EQ-5D-3L, que valora movilidad, cuidado personal, actividades cotidianas, dolor/malestar, ansiedad/depresión y una escala de autoevaluación del estado de salud. Comparamos los resultados con variables demográficas (sexo, edad, situación laboral, estudios, ingresos, pareja) y clínicas (clasificación ASA, estadio tumoral, tiempo desde la realización de la cistectomía, quimioterapia adyuvante, recidiva y complicaciones del estoma). El análisis estadístico incluyó estudio descriptivo, análisis univariante y multivariante. Resultados: Cincuenta y nueve pacientes incluidos, con una media de edad de 69 años (47-84). El tiempo medio desde la cistectomía es de 43 meses (12-83), con un porcentaje de complicaciones asociadas al estoma del 61%.Las complicaciones del estoma se relacionaron con limitaciones en el cuidado personal, dolor/malestar, ansiedad, depresión y calidad de vida en general. El sexo femenino se asocia con limitaciones en las actividades cotidianas y la quimioterapia adyuvante lo hace con la ansiedad/depresión y con la calidad de vida en general. El resto de variables no alcanzaron significación estadística en el análisis multivariante. Conclusiones: Las limitaciones en la calidad de vida en pacientes con cistectomía y conducto ileal se asocian con las complicaciones asociadas al estoma. Otras variables relacionadas son el sexo femenino y la administración de quimioterapia adyuvante
Objective: To determine the variables that affect quality of life of patients treated by radical cystectomy with ileal conduit. Material and method: We analyzed quality of life using the EQ-5D-3L questionnaire. This questionnaire evaluates mobility, personal care, daily activities, pain/discomfort, anxiety/depression and a self-rating scale of the health condition. We compared the result with demographic variables (gender, age, work situation, studies, income, partner) and clinical variables (ASA classification, tumor stage, time since cystectomy was performed, adjuvant chemotherapy, recurrent and complications of the stoma). The statistical analysis included a descriptive study, univariate and multivariate analysis. Results: A total of 59 patients were included in the study, with a mean age of 69 years (47-84). Mean time from cystectomy was 43 months (12-83), with 61% complications associated to the stoma. Stoma complications were related with limitations in personal care, pain/discomfort, anxiety, depression and quality of life in general. Female gender was associated with limitations in daily activities and adjuvant chemotherapy with anxiety/depression and quality of life in general. The rest of the variables were not statistically significant in the multivariate analysis. Conclusions: The limitations in quality of life in patients with cystectomy and ileal conduit are associated with the stoma-associated complications. Other related variables are female gender and administration of adjuvant chemotherapy

This study was undertaken to investigate the relationship between chemical composition and microbial profile of rumen liquid-associated bacteria (LAB) in vivo (Murciano-Granadina goats) and in a rumen simulation system (single-flow continuous-culture fermenters). To achieve this aim, analyses of purine bases along with some molecular techniques (quantitative PCR to assess abundance and DGGE to identify biodiversity and bacterial profile) were carried out. A control diet (AHC) based on alfalfa hay (AH) and concentrate (C) in a 1:1 ratio and two experimental diets (AHCBI and AHCBII), in which concentrate was partially replaced with multinutrient blocks, were used. Diets AHCBI and AHCBII included multinutrient blocks differing in the relative amount of two-stage olive cake and the source of protein (sunflower meal vs. fava beans). We aimed to investigate the effect of these blocks on rumen microbiota to evaluate their potential as safe substitutes of cereal-based concentrates. Similar patterns of response to diet were found for chemical composition, microbial abundances and diversity in LAB isolated from goat's rumen and fermenters. Whereas bacterial density (log10 gene copies/g FM: 11.6 and 9.4 for bacteria and methanogens, respectively, in rumen) and diversity indexes (Shannon index: 3.6) were not affected by diet, DGGE analyses showed that bacterial community profile was affected. The cluster analysis suggested differences in bacterial profile between LAB pellets isolated from the rumen of goat and fermenters. A relationship between chemical composition and bacterial community composition in LAB pellets seems to exist. Changes in the former were reflected in the bacterial community profile. Further research is needed to clarify the relationship between chemical and microbial composition of ruminal bacterial pellets with diets of different quality.

OBJECTIVE: To determine the variables that affect quality of life of patients treated by radical cystectomy with ileal conduit. MATERIAL AND METHOD: We analyzed quality of life using the EQ-5D-3L questionnaire. This questionnaire evaluates mobility, personal care, daily activities, pain/discomfort, anxiety/depression and a self-rating scale of the health condition. We compared the result with demographic variables (gender, age, work situation, studies, income, partner) and clinical variables (ASA classification, tumor stage, time since cystectomy was performed, adjuvant chemotherapy, recurrent and complications of the stoma). The statistical analysis included a descriptive study, univariate and multivariate analysis. RESULTS: A total of 59 patients were included in the study, with a mean age of 69 years (47-84). Mean time from cystectomy was 43 months (12-83), with 61% complications associated to the stoma. Stoma complications were related with limitations in personal care, pain/discomfort, anxiety, depression and quality of life in general. Female gender was associated with limitations in daily activities and adjuvant chemotherapy with anxiety/depression and quality of life in general. The rest of the variables were not statistically significant in the multivariate analysis. CONCLUSIONS: The limitations in quality of life in patients with cystectomy and ileal conduit are associated with the stoma-associated complications. Other related variables are female gender and administration of adjuvant chemotherapy.

CASE REPORT: A 25-year-old woman noticed a painless yellow-orange mass on her right eye. Her visual acuity was 20/20 in both eyes, and a slit-lamp examination showed a yellow-orange mass located at the superior limbus of the right eye. No other ocular abnormalities were observed. DISCUSSION: Surgical excision was carried out and the lesion was sent for histological examination. This showed a granulomatous lesion, rich in Touton-type giant cells, features that are strongly suggestive of juvenile xanthogranuloma (JXG). Ocular involvement occurs in 10% of cases of JXG.

Nitrogen emissions from dairy cows can be readily decreased by lowering the dietary CP concentration. The main objective of this work was to test whether the milk protein yield reduction associated with low N intakes could be partially compensated for by modifying the dietary carbohydrate composition (CHO). The effects of CHO on digestion, milk N efficiency (milk N/N intake; MNE) and animal performance were studied in four Jersey cows fed 100% or 80% of the recommended protein requirements using a 4×4 Latin square design. Four iso-energetic diets were formulated to two different CHO sources (starch diets with starch content of 34.3% and NDF at 32.5%, and fiber diets with starch content of 5.5% and NDF at 49.1%) and two CP levels (Low=12.0% and Normal=16.5%). The apparent digestible organic matter intake (DOMI) and the protein supply (protein digestible in the small intestine; PDIE) were similar between starch and fiber diets. As planned, microbial N flow (MNF) to the duodenum, estimated from the urinary purine derivatives (PD) excretion, was similar between Low and Normal CP diets. However, the MNF and the efficiency of microbial synthesis (g of microbial N/kg apparently DOMI) were higher for starch v. fiber diets. Milk and milk N fractions (CP, true protein, non-protein N (NPN)) yield were higher for starch compared with fiber diets and for Normal v. Low CP diets. Fecal N excretion was similar across dietary treatments. Despite a higher milk N ouput with starch v. fiber diets, the CHO modified neither the urinary N excretion nor the milk urea-N (MUN) concentration. The milk protein yield relative to both N and PDIE intakes was improved with starch compared with fiber diets. Concentrations of ß-hydroxybutyrate, urea and Glu increased and those of glucose and Ala decreased in plasma of cows fed starch v. fiber diets. On the other hand, plasma concentration of albumin, urea, insulin and His increased in cows fed Normal compared with Low CP diets. This study showed that decreasing the dietary CP proportion from 16.5% to 12.0% increases and decreases considerably the MNE and the urinary N excretion, respectively. Moreover, present results show that at similar digestible OM and PDIE intakes, diets rich in starch improves the MNE and could partially compensate for the negative effects of Low CP diets on milk protein yield.

Two in vitro and one in vivo experiments were conducted to investigate the effects of a selection of plant compounds on rumen fermentation, microbial concentration and methane emissions in goats. Treatments were: control (no additive), carvacrol (CAR), cinnamaldehyde (CIN), eugenol (EUG), propyl propane thiosulfinate (PTS), propyl propane thiosulfonate (PTSO), diallyl disulfide (DDS), a mixture (40 : 60) of PTS and PTSO (PTS+PTSO), and bromochloromethane (BCM) as positive control with proven antimethanogenic effectiveness. Four doses (40, 80, 160 and 320 µl/l) of the different compounds were incubated in vitro for 24 h in diluted rumen fluid from goats using two diets differing in starch and protein source within the concentrate (Experiment 1).The total gas production was linearly decreased (P<0.012) by all compounds, with the exception of EUG and PTS+PTSO (P≥ 0.366). Total volatile fatty-acid (VFA) concentration decreased (P≤ 0.018) only with PTS, PTSO and CAR, whereas the acetate:propionate ratio decreased (P≤ 0.002) with PTS, PTSO and BCM, and a tendency (P=0.064) was observed for DDS. On the basis of results from Experiment 1, two doses of PTS, CAR, CIN, BCM (160 and 320 µl/l), PTSO (40 and 160 µl/l) and DDS (80 and 320 µl/l) were further tested in vitro for 72 h (Experiment 2). The gas production kinetics were affected (P≤ 0.045) by all compounds, and digested NDF (DNDF) after 72 h of incubation was only linearly decreased (P≤ 0.004) by CAR and PTS. The addition of all compounds linearly decreased (P≤ 0.009) methane production, although the greatest reductions were observed for PTS (up to 96%), DDS (62%) and BCM (95%). No diet-dose interaction was observed. To further test the results obtained in vitro, two groups of 16 adult non-pregnant goats were used to study in vivo the effect of adding PTS (50, 100 and 200 mg/l rumen content per day) and BCM (50, 100 and 160 mg/l rumen content per day) during the 9 days on methane emissions (Experiment 3). The addition of PTS and BCM resulted in linear reductions (33% and 64%, respectively, P≤ 0.002) of methane production per unit of dry matter intake, which were lower than the maximum inhibition observed in vitro (87% and 96%, respectively). We conclude that applying the same doses in vivo as in vitro resulted in a proportional lower extent of methane decrease, and that PTS at 200 mg/l rumen content per day has the potential to reduce methane emissions in goats. Whether the reduction in methane emission observed in vivo persists over longer periods of treatments and improves feed conversion efficiency requires further research.

We investigated the transport Barkhausen-like noise (TBN) by using nonlinear time series analysis. TBN signals were measured in (Bi,Pb)2Sr2Ca2Cu3O10+δ ceramic samples subjected to different uniaxial compacting pressures (UCP). These samples display similar intragranular properties but different intergranular features. We found positive Lyapunov exponents in all samples, λm≥0.062, indicating the nonlinear dynamics of the experimental TBN signals. It was also observed higher values of the embedding dimension, m>9, and the Kaplan-Yorke dimension, DKY>2.9. Between samples, the behavior of λm and DKY with increasing excitation current is quite different. Such a behavior is explained in terms of changes in the microstructure associated with the UCP. In addition, determinism tests indicated that the TBN masked determinist components, as inferred by |k[over arrow]| values larger than 0.70 in most of the cases. Evidence on the existence of empirical attractors by reconstructing the phase spaces has been also found. All obtained results are useful indicators of the interplay between the uniaxial compacting pressure, differences in the microstructure of the samples, and the TBN signal dynamics.
RESUMEN
The effects of replacing 50% of cereals-based concentrate with feed blocks (FB) including wastes of tomato fruits (diet ACT), wastes of cucumber fruits (diet ACC), or barley grain (diet ACB) on nutrient use, ruminal fermentation, microbial N flow to the duodenum, methane emissions, and abundances of total bacteria and methanogen were studied in goats. Four adult, dry, nonpregnant, rumen-fistulated Granadina goats (32.1 ± 5.52 kg BW) were used and 4 diets were studied in 4 trials by using a 4 × 4 Latin square experimental design. Diets consisted of alfalfa hay plus concentrate in a 1:1 ratio (AC) or 1:0.5 plus FB including wastes of ACT, ACC, or ACB. In each trial, goats were randomly assigned to 1 of the diets. Intake of each FB including ACT, ACC, and ACB were 203 ± 73, 179 ± 39, and 144 ± 68 g·animal(-1)·d(-1), respectively. The ACT and ACC diets did not (P > 0.05) compromise digestible and metabolizable energy, but reduced N retention by up to 29% (P = 0.03). Cucumber-based FB decreased the purine bases (PB):N ratio (P = 0.02) in total bacterial pellets isolated from the rumen content. Tomato-based FB decreased purine derivatives urinary excretion (P = 0.04) and microbial N flow (P = 0.03) without affecting the efficiency of synthesis but decreased methane emission by 28% (P < 0.001) compared with the other diets. Tomato and cucumber-based FB resulted in greater (P < 0.001) rumen VFA concentration and molar proportions of propionate and butyrate (P ≤ 0.02) than AC and ACB diets. No effect (P = 0.07) of diet on total bacteria abundance was observed whereas the abundance of methanogens increased (P = 0.01) with wastes-based FB. Our study suggests that ACC-based FB could replace one-half of the amount of concentrate in goat diet without compromising rumen fermentation and nutrient and energy use and without increasing methane emissions. Blocks including ACT showed an antimethanogenic effect but reduced microbial N flow to the duodenum. Further research is needed to improve both N and energy use of diets including ACT- and ACC-based FB.
