摘要/Abstract

摘要： 为研究一种更有利于提高妊娠母猪生产性能的饲喂方式，为临床生产提供参考信息。于2015年4月在临沂帛乘原种猪繁育有限公司进行试验，将56头3~6胎次配种期接近的妊娠母猪随机平均分为A、B两组，每组妊娠期114天，哺乳期21天。A组采用妊娠期每天1次、哺乳期每天4次和断奶后7天内每天2次的饲喂方式，B组进行传统的妊娠期每天2次、哺乳期每天4次和断奶后7天内每天2次的饲喂方式。结果表明，A组在总产仔数、产活仔数、仔猪出生重、21天断奶仔猪重和断奶后7天发情率等方面均优于B组，且优势明显。规模化猪场母猪在妊娠期内每天采用1次饲喂，其繁殖性能优于2次饲喂。

Abstract: The aim of this study is explore a feeding mode which is more conducive to improve production performance of pregnant sow, and provide reference for practical production. The experiment was conducted in Linyi Bocheng Pig Ltd. in April 2015. 56 sows (3th-6th parity) which had close breeding period were randomly divided into group A and B. The pregnancy period was 114 days and lactation period was 21 days. Pigs in group A was fed 1 time a day during pregnancy period, 4 times a day during lactation period and 2 times a day for 7 days after weaning. Pigs in group B was fed 2 times a day during pregnancy period, 4 times a day during lactation period and 2 times a day for 7 days after weaning. The results showed that group A is better than group B in litter size, alive litter size, piglet birth weight, piglet weight 21 days after weaning and sow estrus rate 7 days after weaning, and the advantages were obvious. Thus feeding pregnant sows 1 time a day during the pregnancy period was better than 2 times a day in reproductive performance.
