苜蓿青贮对奶牛产奶量、乳品质及养殖效益的影响

Effects of Alfalfa Silage on the Milk Yield,Milk Quality and Culture Benefits of Dairy Cow

[目的]为苜蓿青贮在奶牛养殖中的推广和应用提供科学依据。[方法]以苜蓿青贮替代苜蓿干草,进行饲喂效果比较,探讨苜蓿青贮对产奶量及乳品质的影响。[结果]试验组日均产奶量、乳脂率、乳蛋白率、非脂乳固体率、乳糖率分别比对照组高9.13%、1.73%、0.57%、0.42%、0.38%。[结论]在奶牛日粮中适量添加苜蓿青贮,可以有效提高奶牛的产奶量,同时降低饲料成本,从而提高养殖经济效益。

[Objective] The research aimed to provide scientific basis for the popularization and application of alfalfa silage in the culture of dairy cow.[Method] Alfalfa silage was used to replace alfalfa silage and compare the feeding effects.The effects of alfalfa silage on the mild yield and milk quality were discussed.[Result] The daily average milk yield,milk fat percentage,milk protein rate,non-fat solid rate and milk sugar rate in test group were 9.13%,1.73%,0.57%,0.42%,0.38% higher than that in control group.[Conclusion] Adding appropriate amount of alfalfa silage in the diet of dairy cow could effectively enhance the milk yield of dairy cow and decrease the feed cost,so as to enhance the culture economic benefit.
