摘要
用剩余初乳代替全乳培育犊牛是近年来奶牛业中的新课题之一。本文通过1986—1987年的犊牛饲养试验,对犊牛的饲料采食量、生长发育、成活率及经济效益等方面进行了比较系统的研究。研究结果表明,用发酵初乳培育的犊牛与用常乳培育的犊牛相比:(1)耗奶少培育成本低,每头犊牛节约鲜奶415公斤,节省饲料费233.15元。(2)生长发育良好,尤其早期补喂犊牛料,促进了瘤胃的提早发育。(3)抵抗力强、发病率低,成活率高。(4)经济社会效益显著。
It is new research items that breed calf replaced milk by residual olostrum. This article is study about feeds intake, growth and develop survial rate,economic benefit etc.By feeding calf experiments from 1986 to 1987. Compared with breed calf which use general milk, the breed calf which use fermented colostrum are:(1) expend milk is less;breeding expeses is lesser;can lessen fresh milk41.5kg.per calf;can lessen feeds expenses 233.15 yuan (2) Growth and development is very good, especially eat calf starter early, the rumen is devlopedearly.(3) Resisting power is increaed,morbidity is lower,but servival rate is higher(4E)conomic benefit is marked.
