青贮饲料对奶牛采食量、生产性能和相关生化指标的影响

The Effects of Silage on Feed Intake,Production Performance,and Related Biochemical Indicators of Dairy Cows

[目的]分析青贮饲料对奶牛采食量、生产性能和相关生化指标的影响。[方法]选择在山东省潍坊市饲养的100头健康中国荷斯坦牛作为研究对象,随机分成两组,对比分析稻草青贮饲料替换干稻草对奶牛采食量、生产性能和相关血清生化指标的影响。[结果]两组试验奶牛的采食量差异不显著,稻草青贮饲料试验组奶牛产奶量明显高于对照组,稻草青贮饲料试验组奶牛分泌牛奶的乳蛋白率、乳脂率均显著高于对照组。两组试验奶牛的相关血清生化指标均没有显著差异。[结论]本研究使用稻草青贮饲料对奶牛的日采食量、相关血清生化指标没有显著影响,能显著提高产奶性能和乳品质量,这为提高奶牛生产性能和推广使用稻草青贮饲料提供参考。

[Purpose] To analyze the effects of silage on feed intake,production performance,and related biochemical indicators of cows.[Method] 100 healthy Chinese Holstein cows raised in Weifang City,Shandong Province were selected as the research subjects and randomly divided into two groups.The effects of replacing dry rice straw with rice straw silage on feed intake,production performance,and related serum biochemical indicators of cows were compared and analyzed.[Result] There was no significant difference in feed intake between the two experimental groups of cows.The milk production of cows in the straw silage feed experimental group was significantly higher than that in the control group.The milk protein and milk fat rates secreted by cows in the straw silage feed experimental group were significantly higher than those in the control group.There was no significant difference in the relevant serum biochemical indicators between the two experimental cows.[Conclusion] The use of rice straw silage feed in this study did not significantly affect the daily feed intake and related serum biochemical indicators of cows,but could significantly improve milk production performance and dairy product quality.This provides a reference for improving the production performance of cows and promoting the use of rice straw silage feed.
