摘要：

In a dual-purpose farm, located at Maracaibo's basin Lake in a rainy tropical forest zone, the natural sexual behaviour of 300 crossbred cows (Bos taurus x Bos indicus) were observed. Two manuals daily milking, with suckled-calf were taken. The cows were under an artificial insemination technique, teaser bulls and four times visual observations to estrous detection were doing. Signs of estrous in the hetero and homosexual behaviour were observed; flehmen posture, licking and sniffing were more frequent in bull-cow interaction, Bellowing and frequent urination were not evidents within the estral sexual behaviour.
