ABSTRACT The objective with this study was to evaluate the libido and sexual behavior of Pantaneiro stallions in Brazil in two periods, the rainy and dry seasons. Their sexual behavior was evaluated during mating with mares in estrus, and the libido was scored for statistical analysis. The reaction time and time to mount and ejaculate were 78.1±64.6 s and 289.0 s, respectively. The most relevant events of sexual behavior observed in the Pantaneiro stallions were mounting without erection, mounting without […]

ABSTRACT This study analyzed seasonal variations in the testes, the concentration of sex hormones, the parameters of fresh and thawed semen, and the sexual behavior of male Alpine goats from a temperate region in a tropical climate and possible interference with fertility. The maximum and minimum temperature and luminosity were recorded daily, while seminal, hormonal, and behavioral assessments were carried out every fortnight. The maximum and minimum temperature (°C) and luminosity (h) were recorded daily always at 17.00 h. The […]

The objectives of this study were to determine the efficiency of the libido test in corral compared to the test performed at field and to relate them to the gestation rate observed in a breeding season of 120 days. Thirteen Nelore bulls able to reproduce were submitted to the libido test in corral for 3 hours and evaluated by scores every five minutes. Nine of them were submitted to evaluation at field using a bull:cow proportion equal to 1:33. The […]
