养奶牛常用饲料分类及其营养价值

Classification and Nutritional Value of Common Feed for Dairy Cattle

饲料是奶牛养殖场的主要经济成本投入,占整个养殖成本的70%以上。饲料营养价值将直接决定奶牛正常生长和泌乳机能。如果饲料营养价值较差,不能满足奶牛生长发育所需,将会严重影响奶牛正常生产,使养殖场乳汁产量显著下降,甚至会造成养殖场出现严重的经济损失。因此需要明确奶牛在养殖管理过程中常用的饲料种类,并明确饲料营养价值,做到科学搭配饲料,合理使用饲料,确保所选择的饲料满足奶牛生长发育所需,更好地推动奶牛养殖业健康发展。该文主要分析奶牛养殖中常用饲料种类和营养价值。

Feed is the main economic cost input of dairy farm,accounting for more than 70%of the whole cost.The nutritional value of feed will directly determine the normal growth and lactation function of dairy cows.If the nutritional value of feed is poor and can not meet the needs of growth and development of dairy cows,the normal production of dairy cows will be seriously affected,the milk yield of dairy farms will be significantly reduced,and even serious economic losses will occur in dairy farms.Therefore,it is necessary to make clear the kinds of feedstuffs commonly used in dairy cattle breeding and management,and to make clear the nutritive value of feedstuffs,so as to make scientific use of feedstuffs and ensure that the feedstuffs chosen meet the needs of dairy cattle's growth and development,better promote the healthy development of dairy cattle breeding industry.This paper mainly analyzed the feed types and nutritional value in dairy cattle breeding.
