应用糟渣复合型饲料对断奶犊牛生长发育的影响

Effects of the Use of Grain and Slag Compound Feed on the Growth and Development of Weaned Calves

该试验以应用低成本的糟渣复合型饲料为突破口,开展饲喂糟渣复合型饲料对断奶犊牛生长性能的影响,积极探索在肉牛饲喂过程中降本增效的有效途径。试验在甘肃省武威市的武威顶乐牧业有限公司旗下的牧业二场进行,在牧场选取40头60日龄以上的犊牛作为参试牛群,参试犊牛日龄误差10日龄。设对照组和试验组,每个组设参试牛20头,预试期15d,在这期间,统一测量试验期初犊牛的体重、体高、胸围、体斜长、腹围,开展口蹄疫的免疫接种,做好饲料过渡,参试牛的登记等正试期准备工作;正试期60 d。结果发现,应用糟渣复合型饲料犊牛采食量可增加13.3%,日增重增加0.18 kg,饲料利用率可提高0.37个百分点,对犊牛的生长发育起到积极的促进作用。

To investigate the effects of feeding the low-cost slag compound feed on the growth performance of weaned calves,and actively explore effective ways to reduce cost and increase efficiency in the process of beef cattle feeding.Methods:The experiment was conducted in the second farm of Wuwei Dingle Animal Husbandry Co.,Ltd.,Wuwei City,Gansu Province.40 calves over 60 days old were selected as the test cattle,and the age error of the calves was 10 days old.The experiment was divided into two groups,the control group and the experimental group,with 20 cows in each group.The pre-test period was 15 days.During this period,the body weight,body height,chest circumference,body Angle length and abdominal circumference of calves were measured uniformly at the beginning of the test period,and the immunization against foot-and-mouth disease was carried out,and the preparatory work of the trial period was completed,such as feed transition and registration of the tested cattle.The trial period is 60 days.Results:Feed intake,daily gain and feed utilization rate of calves increased by 13.3%,0.18 kg and 0.37 percentage points respectively,which played a positive role in promoting the growth and development of calves.
