The experiment was conducted to study the effect of different silage types on growth performance and economic benefits of beef cattle. Sixty Simmental cattle with similar body weight and good body condition were randomly divided into four groups with 15 replicates per group and one beef cattle per replicate. Beef cattle in test group Ⅰ were fed whole corn silage, those in test group Ⅱ were fed straw silage, those in test group Ⅲ were fed peanut vine silage, and those in test group Ⅳ were fed conformation tree silage with the same concentrate. The experiment lasted for 100 d. The results showed that compared with test group Ⅱ, beef final weight in test group Ⅰ, test group Ⅲ and test group Ⅳ was significantly increased (P<0.05). The average daily gain was extremely increased (P<0.01), and feed to gain ratio was extremely decreased (P<0.01). The order of feed input was test group Ⅲ > test group Ⅳ > test group Ⅰ > test group Ⅱ. The weight gain income of the four groups was 38.50, 28.50, 36.00 and 37.25 yuan/(head·d), respectively. The highest economic benefit of experiment group Ⅰ was 10.74 yuan/(head·d). The experiment indicates that using whole corn silage group has better growth performance, which has the highest economic benefit, it can be popularized and applied in beef cattle fattening.

| Abstract (Chinese): |
试验旨在研究不同类型青贮对肉牛生长性能及经济效益的影响。选择体重相近、体况良好的西门塔尔 牛60头, 随机分为4组, 每组15个重复, 每个重复1头牛。试验Ⅰ组西门塔尔牛饲喂全株玉米青贮, 试验Ⅱ组西门 塔尔牛饲喂稻草青贮, 试验Ⅲ组西门塔尔牛饲喂花生秧青贮, 试验Ⅳ组牛饲喂构树青贮, 各组精料相同。试验期 100 d。结果显示：与试验Ⅱ组相比, 试验Ⅰ组、Ⅲ组、Ⅳ组肉牛末重均显著提高 (P<0.05), 平均日增重均极显著 提高 (P<0.01), 料重比均极显著降低 (P<0.01)。饲料投入排序为试验Ⅲ组>试验Ⅳ组>试验Ⅰ组>试验Ⅱ组；各组 试验牛增重收入分别为38.50、28.50、36.00和37.25 元/(头·d)；试验Ⅰ组的经济效益最高, 为10.74 元/(头·d)。研 究表明, 使用全株玉米青贮饲喂肉牛的生长性能较好, 经济效益最高, 可在肉牛育肥中推广应用。 [ABSTRACT FROM AUTHOR] |
