针对导致母猪生产水平低原因之一胚胎死亡问题开展研究,通过对猪胚胎发育危险期的分析,探讨了造成胚胎死亡的遗传、营养、疫病、环境、药物及其他因素,提出了提高胚胎成活率的综合措施,为养猪生产中提高母猪产仔率提供参考。
Embryonic death problem was studied as one of the reasons of leading to low production of sow, meanwhile, through the analysis of critical phage during embryonic development, inheritance, nutrition, disease, environment, drug and other factors were discussed in this paper. We put forward comprehensive measures to improve embryonic survival rate, which can provide reference for improving sow fertility rate.
