ANALYSIS OF THE SEXUAL BEHAVIOR OF BULLS OF THE TABAPUÃ BREED

Abstract

Beef cattle is one of the main sectors that drive the national economy, given the great generation of employment, presence in the consumer market, and exports. Among the various services generated, technical assistance to producers stands out, who work in several areas and, especially reproduction, which is a great ally to bovine production, because through it it is possible to monetize the creation with the use of reproducers with high fertility potential boosting livestock productivity. Therefore, the andrological evaluation in the sires is an important factor in selecting superior animals, seeking to improve the fertility of the herd. The present study aimed to analyze the sexual behavior of bulls of the Tabapuã breed, through the libido test, as part of the andrological examination. Ten young bulls of the Tabapuã breed were used, aged between 24-43 months, with an average weight of 375kg, without sexual experience. The libido test was performed from the contact of males with females in estrus and out of estrus to assess sexual interest. It was observed that half of the animals were classified with low libido (50%) and the other part with medium (30%) and high (20%) libido. In addition, it was observed that the most frequent sexual events were the identification of estrus. Finally, given the results of animals classified with low libido, it is suggested that sexual inexperience is correlated, and it is recommended to insert these cattle with high libido bulls so that they can observe the behaviors and gain experience.
