Comportamento sexual de carneiros Ideal com ovelhas sincronizadas

Abstract

The attitudes of the animals ahead to any situation are known as behavior. The knowledge of animal behavior has many benefits, including the reduction of stress increasing animal productivity. During the breeding season the behavior is of great importance affecting directly in mating and thus the reproductive herd rates. This work aims to evaluate the behavior of sheep with and without prior experience with sheep synchronized in the reproductive period. The work was carried out on a farm in the municipality of Santana do Livramento the state of Rio Grande do Sul/Brazil, with three sheep race Ideal and fifty-two sheep by synchronized methods. The sheep had different ages, weights, body condition and scrotal circumference. During the breeding season, which lasted sixty days, males stayed with the sheep, but for a better view of behavioral activities, the animals were brought to picket smaller in the morning and returned to the paddock at the end of the day, the same had massive food and water available. The behavioral assessments were carried out in a five-day period and observations integrated shifts in the morning and afternoon. Significant differences were observed (P <0.05) for the pursuit of variables, disinterest, penile exposure and attempt to ride within each of the evaluated shifts, morning and afternoon.When evaluating the rams per turn and expression of each behavior was observed difference in behavior nosed (P = 0, 0284). Previous experience as well as body weight and scrotal circumference interfere in sheep behavior expression.
