摘要
为了研究不同饲养模式对犊牛消化道形态学结构的影响,试验选择20头体重相近的荷斯坦哺乳犊牛,采用完全随机试验设计,将犊牛分为2组,分别为对照组和试验组,对照组喂颗粒精料+牛奶,试验组饲喂颗粒精料+牛奶+优质牧草。结果表明:对照组犊牛瘤胃乳头数量和长度显著高于试验组(P<0.05),瘤胃厚度低于试验组(P<0.05)。说明添加牛奶和精料可以促进犊牛的瘤胃乳头发育,而添加牛奶、精料和干草则可促进瘤胃容积和组织的发育。
20 healthy Holstein calves with close body weight were selected and divided into 2 groups,including the control group and the experimental group,which were 10 calves with half male and female in each group using a completely randomized design.The fine-grained concentration and fresh milk were fed in the control group.Grained concentration and high quality hay and fresh milk were fed in the experimental group.The results showed that the quantities and length of rumen rapillae in calves in the control group were significantly more than that of in the experimental group（P〈0.05）,and the thickness of rumen were less than that of in the experimental group（P〈0.05）.It concludes that the nipples of rumen in calves can grow and develop well in adding fine-grained concentration and fresh milk,while it may promote the development of stomach capacity and tissue with adding the fine-grained concentration and high quality hay and fresh milk.
