摘 要：
选取年龄、胎次、品种基本一致的哺乳母猪20头,随机分成对照组和试验组,试验分两批进行,每批10头。在相同的环境条件下,母猪自由饮水,饲喂同一哺乳母猪料。母猪分娩后4d内,采用原场饲养制度,逐步增加哺乳母猪采食量,第5天开始,对照组采用不限量饲喂,试验组采用限量和添加哺乳母猪补充料的饲喂方式,仔猪21日龄断奶。结果显示:两组仔猪21日龄的断奶窝重、母猪断奶后再发情时间和母猪哺乳失重等差异均不显著(P>0.05)。
This experiment selected 20 sows with the similar age and breed type, dividing into two groups. Under similar environment, the sows and piglets had free access to water, the sows were provided with the same kind of feed. The sows were bred under the same method of the pig farm within 4 days after farrowing. From the fifth day on, the control group was fed by voluntary feed intake, while the treatment group was fed by limited feeding. The piglets were weaned at 21-day-old. The results show that the limited feeding group, compared with the unlimited feeding group, had no significant difference both in the litter weaning weight of 21-day-old and the weaning-to-estrus interval of sow (P>0.05).
