二甲酸钾对泌乳期母猪生产性能的影响

Effect of potassium diformate on the production performance of lactating sows

试验旨在研究二甲酸钾(KDF)对泌乳母猪生产性能的影响。试验选用104头泌乳母猪,按照品种、日龄基本一致的原则随机分为2组,每组4个重复,每个重复13头,其中对照组饲喂正常泌乳母猪料,试验组在正常泌乳母猪料中添加8 kg/t二甲酸钾,试验期34 d。结果表明,泌乳期结束,试验组泌乳母猪头均失重(-25.13 kg)比对照组减少(-32.81 kg)30.56%(P<0.1);试验组母猪日均采食量与对照组无差异(P>0.1);试验组母猪断奶至发情时间比对照组少0.74 d,但差异不显著(P=0.21);试验组断奶仔猪成活率、断奶窝重与对照组差异不显著(P>0.1)。在泌乳母猪日粮中添加二甲酸钾能降低泌乳期母猪体重损失,对泌乳期母猪生产性能有积极的影响。

This experiment was conducted to study the effect of potassium diformate （KDF） on the production performance of lactating sows. 104 lactating sows were randomly divided into 2 groups according to the principle of variety and day of age. Each group had 4 repetitious, each repeated 13. The control group was fed with normal lactation sows feeds, and the test group added 8 kg/t of KDF to normal lactation sows feeds, and the test period was 34 days. The results showed that the weightlessness of the lactating sows in the test group （-25.13 kg） decreased 30.56% （P〈0.1） compared to the control group （-32.81 kg） , and there was no difference on average daily feed intake（P〉0.1）. The time from weaning to estrus in the experimental group was 0.74 days less than that in the control group, but the difference was not significant （P=0.21）. The survival rate and the weaning weight of the weaned piglets in the experimental group were not significantly different from the control group （P〉0.1）. Adding potassium diformate in the diet of lactating sows feeds can reduce the weight loss of sows during lactation, and has a positive effect on the production performance of sows during lactation.
