母猪胎次结构对其繁殖性能的影响研究
Study of Sows Herd Parity Structure on the Reproductive Performance
摘要
Abstract
The reproductive performance of sows is one of the key factors to determine the level and efficiency of pigproduction,and reasonable herd parity structure make the reproductive performance of sows to reach the maximum at the population level.At present,the herd parity structure of sows does not have a unified standard,and various factors in actual production also restrict and affect the herd parity structure of sows.In this study,we used computer simulation technology,according to the process and production parameters of modern pig production,to research a pig farm which had 600 breeding sows production data for ten consecutive years.According to PSY (productivity per sow per year),put forward a reasonable and suitable herd parity structure for breeding sows.The results showed that the best herd parity structure for the first parity to tenth parity is 3.40％,4.26％,12.48％,19.15％,19.93％,17.02％,12.70％,7.87％,2.48％,0.71％.关键词
