摘要
选择不同日粮类型肉牛养殖户10户,参试生长公牛25头,参照肉牛营养需要和饲养标准,设计不同饲粮组合类型及日粮配方。随机分为6组,试验1、23、组按设计标准配制日粮饲养,4、5、6组(CK)按传统方法饲喂,同期进行育肥试验。结果表明,试验12、、3组头均日增体质量效果均比4、5、6组(CK)有明显提高。其中,试验1组期内平均日增体质量分别比试验4、5、6组(CK)提高94.22%、117.18%和145.07%(P<0.01)。
25 heads growing beef bulls were selected from 10 beef farms.The different ration ingredients and formulas were designed according to nutritive requirement and feeding standard of beef cattle.25 heads growing beef bulls were divided into 6 treatment groups at random.Treatment group 1,2 and 3 were fed with feeding standard,but control group 4,5 and 6 were fed what farmers holds and used traditional ways.The results indicated that the average daily gain per head of treatment group 1,2 and 3 were higher obviously than control group 4,5and 6（P〈0.05 or P〈0.01）.The average daily gain of treatment group 1 was higher than control group 4,5and 6,and enhanced 94.22%,117.18% and 145.07% respectively.
