饲喂不同比例冬牧70黑麦草青贮饲料对肉牛育肥效果的影响

Effect of feeding different proportion of Secale Cerale Grass silage on beef cattle fattening

为了验证冬牧70黑麦草青贮对肉牛育肥的效果,试验将西门塔尔肉牛公牛40头随机分为4组,试验1,2,3组饲料中分别添加30.0%、52.5%、75.0%冬牧70黑麦草青贮,对照组不添加,对肉牛增重情况和经济效益进行测定。结果表明:试验1组肉牛末重、累计增重和平均日增重均显著高于试验2,3组和对照组,试验1组比试验2,3组和对照组分别多盈利1 226.68,1 345.88,544.98元。说明在肉牛日粮中添加适量的冬牧70黑麦草(30%左右)青贮可有效提高肉牛养殖经济效益。

The aim of the present study was to verify the effect of Secale Cerale Grass silage on beef cattle fattening. The 40 Simmertal bulls were radomly divided into 4 groups. The weight gain and economic benefit of beef cattle were determined by adding different proportions of Secale Cerale Grass silage to the diet. The forages of group 1, 2 and 3 were supplemented with 30.0%, 52.5% and 75.0% Secale Cerale Grass silage, respectively. The control group was not supplemented with the silage. The results showed that the final weight, cumulative weight gain and average daily gain of the beef cattle in group 1 were significantly higher than those in the group 2 and 3 and control group. More profits of ￥1 226.68, ￥1 345.88, ￥ 544.98 were obtained in group 1 compared with the group 2, group 3 and control group, respectively. The results indicated that the supplement （ about 30% ） of Secale Cerale Grass silage in the diet could effectively improve the economic benefit of beef cattle breeding.
