青贮玉米在奶牛日粮中的应用效果研究
Journal: Agricultural Science DOI: 10.12238/as.v8i6.3085
Abstract
青贮玉米是一种常用的饲料,但它在奶牛日粮中的具体效果还需要更多研究支持。本研究通过对比试验探究青贮玉米对奶牛生产性能的影响,实验组奶牛日粮中添加一定比例青贮玉米,对照组采用常规日粮。试验期间记录采食量、产奶量及乳成分(乳蛋白、乳脂肪、乳糖含量),研究发现,青贮玉米不仅能提高饲料利用率,还可能通过促进消化吸收优化乳成分。这些结果说明,在奶牛日粮中添加青贮玉米可有效提升产奶量和牛奶品质,对奶牛养殖业具有实际应用价值。未来需进一步研究不同添加比例对长期健康的影响。
