In this restricted review of the literature on libido and mating behavior in bulls, boars and rams it is assumed that libido and mating ability are important traits which can affect production significantly in food and fibre producing animals. These traits are strongly influenced by genetic factors, they vary widely in their expression among individuals and they can be reliably assessed or measured. Rearing young post-puberal males in all-bachelor groups can delay or inhibit the subsequent expression of heterosexual mating behavior. In the species reviewed, females adopt the major role in seeking sexual partners. Visual cues are of greater importance than olfactory cues in eliciting male sexual response. Bulls and rams rend to distribute their services among receptive females within their genetic limitations with females newly in estrus being most attractive to the males. Social interactions among males in multi-sire groups can markedly influence the reproductive performance of both individual males and the female herd or flock. Single sire breeding, while potentially more efficient than multi-sire breeding, is dependent upon the reproductive capabilities of the sire. Proper assessment of factors such as libido and mating ability before breeding can greatly reduce the possibility of poor reproductive performance from single sires.
在本次对公牛、公猪和公羊性欲及交配行为的文献综述中,假定性欲和交配能力是重要性状,会对肉用和毛用家畜的生产产生显著影响。这些性状受遗传因素强烈影响,个体间表现差异很大,且能得到可靠评估或测量。将青春期后的年轻雄性饲养在全单身群体中,会延迟或抑制随后异性交配行为的表现。在所综述的物种中,雌性在寻找性伴侣方面起主要作用。在引发雄性性反应方面,视觉线索比嗅觉线索更重要。公牛和公羊倾向于在其遗传限制范围内,将交配机会分配给处于发情期的雌性,其中刚进入发情期的雌性对雄性最具吸引力。多父本群体中雄性间的社会互动,会显著影响个体雄性以及雌性畜群或羊群的繁殖性能。单父本配种虽然可能比多父本配种更高效,但取决于父本的繁殖能力。配种前对性欲和交配能力等因素进行恰当评估,可大幅降低单父本繁殖性能不佳的可能性。
