摘要
根据某猪场淘汰的203头母猪的生产记录,对不同初配日龄母猪的头胎产仔数、产仔胎数及产仔总数进行统计分析。结果表明,240～269日龄的初配母猪头胎产活仔数最少,270～299日龄的初配母猪平均产仔胎数最少,300～329日龄的初配母猪平均产仔胎数和产活仔总数最高,210～239日龄的初配母猪平均产仔胎数最低。从最佳经济效益来看,母猪的最佳初配日龄为210～239日龄。
According to the production data of 203 eliminated sows in a pig farm,the litter size at the first parity,parity number,total litter size of sows with different first-mating day were analyzed. The results showed that the alive litter size at the first parity of sows with the first-mating day of 240-269 day-old was the least,the average parity number of sows with the first-mating day of 270-299 day-old was the least,the average parity number and the total alive litter size of sows with the first-mating day of 300-329 day-old were the highest. The average parity number of sows with the first-mating day of 210-239 day-old was the least. To the best economic benefits,the best first-mating day of sows was 210-239 day-old.
