Resumo
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 ejaculation, smelling, and vocalizing. In general, the season did not affect the libido of stallions. Even with the high temperatures and humidity, which could cause thermal stress, the stallions showed good libido score during most of evaluations, with some individual differences. Pantaneiro stallions are able to breed mares during the entire year and could facilitate the breeding management to raise the number of Pantaneiro horses of the herds and optimize the use of the stallions during the breeding season, with more females per male.(AU)
