母猪发情诱导与鉴定技术研究进展
Research progress in estrus induction and detection in pigs
摘要
Abstract
The evolving scale of pig breeding has promoted the batch production based on induction and the synchronization of estrus and ovulation regulation.However,the annual renewal rate of about 30%in the fertile sows in batch production highlights the significance of the managements of the gilts in ensuring the stable and sustainable development of pig farms,in which the onset of puberty is a reliable indicator of gilt reproductive performance.However,the sexual development and maturity of gilts is compromised by the lack of boar stimulation by maternal separation in the scale breeding system and about 25%of primiparous sows behave with an irregular cycle of estrus.This review summarizes the research progress and the development trend of sow estrus induction and detection technology to provide technical support for the improvement of the reproductive performance of sows and the production efficiency of the pig industry.关键词
