The Potential Effects of Social Interactions on Reproductive Efficiency of Stallions

The reproductive efficiency of stabled domestic stallions is often lower than what could be expected from observations in feral herds. In the wild, stallions typically live with mares in harem bands, with other stallions in bachelor bands, or occasionally in mixed-sex transitional bands. We, therefore, argue that permanent contact with mares may increase reproductive efficiency of stallions suffering from low libido and/or fertility. We also provide a summary of our present knowledge of natural conditions, management, and husbandry of domestic stallions, and of intra- and intersexual behavioral interactions in horses.     

促性腺释放激素对公兔繁殖性能的影响

本试验研究了促性腺释放激素对公兔繁殖性能的影响。试验结果表明促性腺释放激素可以显著提高公兔的性欲、精子浓度(P<0.05)、精子活力(P<0.05)和每次射精的活精子数(P<0.01)。射精量也有所增加,但差异不显著。
