脂肪酸钙对泌乳奶牛生产性能的影响

[目的]为了验证脂肪酸钙在泌乳奶牛日粮中的作用。[方法]在泌乳牛日粮中添加200~400 g的脂肪酸钙进行处理,设试验1、试验2、对照组3个组加以观察。[结果]试验1、试验2与对照组在0.01水平上差异显著,试验1与试验2在0.05水平上差异不显著。说明在奶牛日粮中添加200 g脂肪酸钙与添加400 g脂肪酸钙均能显著提高产奶量、乳脂率,而添加200 g与添加400 g并无显著差异。[结论]脂肪酸钙开发前景广阔,是充分发挥高产奶牛潜力的优质饲料添加剂。

Effect of Fatty Acid Calcium on the Performance of Lactating Dairy Cows

To examine the effect of fatty acid calcium on the ration of lactating dairy cows. Add 200 - 400 g fatty acid calcium as the treatments and set up Experiment 1, experiment 2 and the control group a total number of three groups for observation. The differences of Experiment 1, experiment 2 and the control group were significant at the level of 0.01. The differences of Experiment 1, experiment 2 and the control group were insignificant at the level of 0.05, This has demenstrated that the addition of 200 g and 400 fatty acid calcium had significantly improved milk yield and milk fat percentage while the addition of 200 g or 400 g had no significant differences. Fatty acid calcium has broad development prospect and is a quality feed additive that can bring the potential of high-yielding dairy cattle into full play.
