摘 要:新吉林黑猪作为东北优良的地方品种深受养殖户的喜爱,做好日常饲养管理是提高新吉林黑猪养殖经济效益的关键。母猪年提供断奶仔猪数(PWSY)经常被用作比较不同种猪群彼此繁殖性能的基准度量单位。在PWSY的组成部分中,断奶仔猪数以及母猪年产窝数是经常受到关注的指标。如何充分发挥母猪的繁殖性能,增加养殖场经济效益是养猪生产运行中的重点。而母猪生产中,其繁殖性能会受到外界多种因素影响,文章从母猪群胎次结构、种畜选育、饲养管理、配种、常见问题等方面对影响母猪繁殖性能的关键因素进行简单的阐述及分析,并总结影响母猪繁殖性能的技术措施。As a fine local breed of Northeast China,Xinjilin black pigs are well loved by farmers,and daily breeding management is the key to improve the economic benefits of black pig breeding in Xinjilin.The number of weaned piglets provided per sow year(PWSY)is often used as a benchmark measure to compare the reproductive performance of different breeding herds.Among the components of PWSY,the number of piglets weaned and the number of litters per year are often the indicators of concern.How to give full play to the reproductive performance of sows and increase the economic benefits of farms is the focus of pig production and operation.In sow production,its reproductive performance will be affected by a variety of external factors.In this article,the key factors affecting the sow's reproductive performance are studied in terms of sow herd parity structure,breeding,breeding management,mating,and common problems.Briefly explain and analyze,and summarize the technical measures that affect the reproductive performance of sows.
