The aim of this study was to determine the occurrence of antibodies IgG against Neospora caninum and evaluate the risk factors associated with the infection in ovine herds, State of Sergipe, Brazil. Blood samples (n=1200) were collected from sheep raised in 60 sheep run located in the three mesoregions of the State of Sergipe, between 2011 e 2012. Antibodies were investigated by Indirect Immunofluorescence Antibody Test of which cutoff point was 50 and positive samples were diluted in base 2 until the last positive titer. Data from 15 variables was obtained from questionnaires given to farmers. Absolute and relative frequencies were determined and the risk factors were analyzed by Pearson's Qui-Square test (p≤0,05). The occurrences of serum reactive sheep were 39.83% (478/1200). The occurrences of positive sheep and sheep run were 55.88% (380/680) and 88.24% (30/34) in the Eastern region; 21.42% (60/280) e 42.85% (6/14) in dry region and 15.83% (38/240) e 41.67% (5/12) in the backwoods respectively. Antibody titers ranged from 50 (n=459), represented 96.02% (459/478) of seropositive samples to 6400 (1/478). Among the significant variables in the multivariate analysis were considered risk factors for infection with N. caninum were, sheep run located in Eastern region (p=0.000, OR=4.64, CI95%=3.36-6.41); standing and running water sources (p=0.000 OR=2.03, CI95%=1.41-2.92), absence of quarantine (p=0.000, OR=2.71, CI95%=2.08-3.53), absence of dunghill (p=0.000, OR=3.14, CI95%=2.45-4.02), presence of dogs (p=0.000, OR=2.74, CI95%=1.73-433), presence of wild animals (p=0.000, OR=3.45, CI95%=2.44-4.87) and subsistence (p=0.000, OR=4.99, CI95%=3.15-7.92) or reproduction (p=0.002, OR=1.74, CI95%=1.22-2.49) livestock were important risk factors. Our results highlight the occurrence of N. caninum in the ovine herds from State of Sergipe. Management and location of sheep runs were important risk factors associated to the infection.INDEX TERMS: Neospora caninum, infection, parasite, sheep, risk factors, indirect fluorescent antibody test.

Granjas avícolas y autosuficiencia de maíz y soya: caso Tungurahua-Ecuador

et al. 2018

Objetivo: caracterizar las granjas avícolas y la autosuficiencia de maíz y soya, en Tungurahua-Ecuador. Metodología: se realizaron entrevistas a noventa avicultores seleccionados mediante muestreo no probabilístico; se utilizó estadísticas de producción y exportaciones reportadas por la Asociación de Fabricantes de Balanceados (AFABA) y el Ministerio de Agricultura, Ganadería, Acuacultura y Pesca (MAGAP), y se calcularon índices de Tasa Media de Variación Acumulada y autosuficiencia y dependencia alimentaria. Resultados: en Tungurahua el 78% de avicultores se dedican a la crianza de aves de postura y el 62% tienen instalaciones semiautomatizadas. El 100% de maíz y soya utilizado por la avicultura de Tungurahua, procede de otras provincias e importaciones internacionales. Entre el 2007 y 2016, el maíz registró un índice de autosuficiencia promedio anual de 0.9, mientras que la soya registró 0.08. Limitaciones: la información estadística de producción nacional e importaciones de granos se encontró dispersa. Conclusiones: los resultados indican la presencia de diversos tipos de sistemas de producción avícola. Éstos, según el nivel tecnológico, van desde los artesanales hasta los automatizados. Así mismo, la producción nacional alcanza a cubrir con dificultad la demanda nacional del sector avícola, no así la soya nacional que cubre una mínima parte. Con base en éstos resultados se sugiere mantener la política de sustitución de importaciones de maíz amarillo y ampliar a la soya.

“…Therefore, the thermal environment, which encompasses temperature, humidity, air speed and radiation, interferes directly with breeding performance, changing food consumption and welfare of animals (PONCIANO et al, 2011;PONCIANO et al, 2012;SANTOS et al, 2014). Accordingly, environment inside the aviary sheds must be controlled so that the birds can be reared within a thermal comfort zone, avoiding negative thermal effects on animal yield (ALMEIDA & PASSINI, 2013;CORDEIRO et al, 2010;ROCHA et al, 2010;CAMPOS et al, 2013).…”

Determination of thermal comfort zone for early-stage broilers

et al. 2016

Environmental temperatures currently considered within comfort zone for broiler rearing may be misleading or even obsolete from actual values. Some factors such as animal genetics, nutrition and poultry management, mainly acclimatization to tropical and subtropical conditions, influence in determining the comfort zone for birds. This study aimed to evaluate the effects of five different thermal environments on animal welfare and rearing performance of broiler chickens, setting an ideal temperature range (comfort zone) for each of the first three weeks of poultry breeding. The chicks (375) were randomly placed into five climatic chambers set to distinct thermal conditions, being: one as recommended by the literature, another as stated by CASSUCE and the other three at different levels of apparent cold stress (mild, moderate and severe). The findings showed that best poultry performance and ideal comfort indices (based on Black Globe Humidity and Temperature Index) were achieved within a temperature range between mild cold and CASSUCE comfort temperature, rather than those previously reported in the literature.
