摘要
为探索饲喂不同比例全株玉米青贮对肉牛犊牛肥育性能及养殖效益的影响,选择36头体重和月龄相近的架子牛,分别饲喂全株玉米青贮添加比例(占粗饲料比例,以干物质计)为30%、50%、61%、70%、90%、100%的全价日粮,观察其对架子牛的肥育性能、健康情况及经济效益的影响。结果显示:日粮粗饲料中全株玉米青贮适宜添加比例为30%-70%;添加比例为70%时试验牛日增重最高,添加比例为30%时试验牛的料重比和增重成本最低,日效益最高。
In order to explore the effect of different ratio of whole corn silage on fattening performance and breeding efficiency of on beef calves, 36 beef calves with similar weight and age were selected to feed them with the ratio of 30%, 50%, 70%, 90%, 100% whole corn silage in TMR for observing the effect onfattening performance, health condition and economic benefit. The results indicated the appropriateratio range of whole corn silage in TMR for growing cattle is 30%-70%, the cattle get the highest average daily gain of body weight when the ratio is 70%, the cattle get the best feed conversion ratio, the least feed cost and the best benefit when the ratio is 30%.
