摘要
奶公犊牛培育是奶牛肉用养殖的关键阶段,饲粮的营养水平和结构对犊牛的正常生长发育至关重要。蛋白质是重要的营养物质,在犊牛的组织生长、机体免疫等方面发挥作用。适宜的蛋白质含量可以改善犊牛饲粮利用率和生长性能。文章主要从犊牛颗粒料中蛋白质水平优化对犊牛生长性能、瘤胃功能等方面的影响进行了综述,为犊牛的精准饲养提供参考依据。
The cultivation of dairy male calves is a key stage in the cultivation of dairy beef.The nutritional level and structure of the diet are essential for the normal growth and development of calves.Protein is an important nutrient that plays a role in the growth of yak tissue and immunity.Appropriate protein content can improve the utilization and growth performance of yak diet.In the paper,the effects of protein level optimization on the growth performance and rumen function of yak granules were reviewed,which provided a reference for the accurate breeding of yak.
