| Seventy-seven ewes were randomly divided into groups according to parturition season and suckling mode [Rainy season: continuous (n=14) and controlled (n=13); Dry season: continuous (n=25) and controlled (n=25)]. The controlled suckling mode, in both seasons, resulted in a decrease in variables, intervals between parturition and first estrus (reduction of 27.11 and 11.46 days for rainy and dry season, respectively; P<0.05) and between parturition and estrus of conception (reduction of 12.81 and 13.58 days, for rainy and dry season, respectively; P<0.05). As to the lambs, the weight gain was higher in animals subjected to controlled suckling in relation to continuous, especially when lambing occurred in the rainy season (17.83±0.56 vs. 13.95±0.52kg... |

| Avaliaram-se o consumo de matéria seca, a produção de leite e os indicadores de estresse térmico de vacas Pardo-Suíça alimentadas com castanha de caju no semi-árido do Nordeste do Brasil. Doze animais foram distribuídos em um ensaio de reversão, com quatro tratamentos: 0, 8, 16 e 24% de castanha no concentrado. As vacas receberam cana-de-açúcar à vontade e sete quilos de concentrado por dia. Maior consumo de matéria seca de cana-de-açúcar foi observado no tratamento com concentrado sem castanha (7,70kgMS/dia) em relação aos tratamentos com 16% e 24% de castanha (7,35 e 7,05kgMS/dia, respectivamente). O consumo no tratamento com concentrado sem castanha não diferiu do consumo no tratamento com 8% (7,59kgMS/dia). Não houve efeito dos tratamentos sobre a... |

| The present study aimed to verify the caprine semen characteristics during dry and rainy seasons in the Brazilian Northeast, and the influence of these seasons on cooled semen. Seminal volume, concentration, percentage of motile cells, vigor and spermatic morphology, as well as biochemical profile (fructose, citric acid, P, Ca2+, Mg, total proteins and phospholipase A2 activity) were analyzed. It was observed a reduction (P<0.05) in normal sperm morphology, fructose, citric acid, P, Mg and total protein concentration during the dry season, which did not affect the motility, vigor, volume and sperm concentration. Phospholipase A2 activity was increased during the dry season (P<0.05). The analysis of the semen cooled at 4ºC during 48 hours showed... |
