糟渣复合型饲料对肉牛增重的影响研究

Study on the Influence of Slag Compound Feed on Weight Gain of Beef Cattle

该试验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肉牛生长的影响,探索肉牛养殖增收的新方法、新材料。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1龄以上的架子育肥牛作为参试牛群,参试育肥牛日龄误差10日龄。试验设对照组和参试组2个组,每个组设参试牛20头,预试期15 d,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180 d。应用糟渣复合型饲料进行育肥,育肥牛日增重较常规配混合饲料可增加0.17 kg,精饲料料重比可降低0.24,一个育肥期可增收992元,应用糟渣复合型饲料是肉牛生产中降本增效的措施之一。

The experiment takes the low-cost lees and slag compound feed as a breakthrough to carry out the influence of feeding lees and slag compound feed on the growth of beef cattle and explore new methods and new materials to increase the income of beef cattle breeding.The experiment was carried out in the second farm of Wuwei Dingle Animal Husbandry Co.,Ltd.,Wuwei City,Gansu Province.40 fattening cattle above 1 year old were selected as the test cattle,and the age error of the cattle was 10 days.The experiment was divided into two groups,the control group and the test 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 belly circumference of calves were measured uniformly at the beginning of the trial 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 the registration of the test cattle.The trial period was 180 days.Compared with conventional mixed feed,the daily weight gain of fattening cattle was increased by 0.17 kg,the feed to gain ratio of concentrate feed was decreased by 0.24,and the income was increased by 992 yuan in one fattening period.The application of fattening compound feed was one of the measures to reduce cost and increase efficiency in beef cattle production.
