In the past 30 years, sows have been successfully selected for a shorter weaning-to-oestrus interval and increased litter size. This review discusses the consequences of this selection for the reproductive physiology of sows, including the consequences for litter characteristics at birth. It also discusses breeding and management opportunities to deal with this changed genetics.
在过去30年里,母猪已成功选育出断奶至发情间隔更短且产仔数更多的品种。本综述讨论了这种选育对母猪生殖生理的影响,包括对出生时仔猪特征的影响。它还讨论了应对这种基因变化的育种和管理机会。
