摘　　要：本文旨在讨论影响断奶母猪发情率的原因及其解决措施,通过分析得出影响断奶母猪发情率的因素有营养、膘情、胎次、环境控制、霉菌毒素、光照、诱情、生殖系统感染、断奶日龄、卵巢囊肿以及一些疾病因素。根据这些原因对母猪发情的影响,讨论其应对措施。在仔猪断奶前后应做好母猪的饲养管理工作,根据母猪膘情合理饲喂,做好母猪生活环境的控制工作,提早预防母猪生殖道疾病。因此,合理控制母猪舍的光照时间,做好母猪的诱情、查情等工作,合理控制好断奶日龄,定期做好疾病的预防。为提高断奶母猪发情率,增强繁殖性能,提供理论依据。The purpose of this study was to discuss the causes of estrus rate of weaning sows and its solutions.Through analysis,the factors affecting estrus rate of weaning sows were found to be nutrition,fat condition,parity,environmental control,mycotoxin,light,inducement,reproductive system infection,weaning age,ovarian cyst and some diseases factors.According to the influence of the caused of diseases,the countermeasures were discussed.Sows feeding and management should be done well before,during and after weaning,such as reasonable feeding according to sow fat,control of the environmental control of sows,and prevention of reproductive diseases in sows earlier.It was essential to reasonably control the illumination time in the piggery and the weaning age,do a good job on sow estrus induction and investigation,and complete the disease prevention work regularly.The conclusion of this study provided a theoretical basis for improving estrus rate and reproductive performance of weaned sows.
