乳酸菌发酵青贮玉米饲料对奶牛机体健康和生产性能的影响

乳酸菌作为一种应用广泛的微生物制剂,有着改善奶牛机体胃肠道健康、增加产奶量、提高免疫力和改善乳品质的作用,可直接与奶牛饲料搭配进食或用于青贮玉米饲料的制备。玉米作为青贮饲料的优质原料之一,可全株发酵,营养价值丰富,适于奶牛饲喂。本文总结了乳酸菌制剂的作用原理和应用、青贮玉米饲料的制备要点以及青贮玉米饲料添加乳酸菌后对奶牛生产性能、机体健康的影响,旨在为奶牛优质饲料的制备及应用提供参考,促进奶牛养殖业的发展。

Research Progress on the Effect of Lactic Acid Bacteria Silage Corn Feed on Dairy Cows

Lactobacillus,as a widely used microbial preparation,can improve the gastrointestinal health of dairy cows,increase milk production,improve immunity and improve milk quality,and can be fed directly with dairy cattle feed or used in the preparation of corn silage. As one of the high-quality raw materials for silage,maize can be fermented whole plant,which is rich in nutritional value and suitable for feeding to dairy cows. This paper summarized the principle and application of lactic acid bacteria preparation,the preparation of corn silage,and the effect of adding lactic acid bacteria to corn silage on the production performance and health of dairy cows,aiming to provide reference for the preparation and application of high quality feed for dairy cows and promote the development of dairy farming.
