| 摘 要： | [目的]为了探讨肉牛育肥过程中的糖蜜用量。[方法]从120头西杂牛中随机选48头,分为8组,每组．6头。以四个处理2个重复进行试验;Tr1为对照组,饲喂全株玉米秸青贮加精料;Tr2-Tr1＋糖蜜1kg,Tr3-Tr1＋糖蜜2kg,Tr4-Tr1＋糖蜜3kg。试验期100d,其中预试期·10d,试验期90d。每30d称重1次,在上午空腹称重。本试验数据采用SAs软件进行统计分析。[结果]表明：添加甜蜜的各组与对照组比较,净增重均有显著性差异（P〈0．05）,Trl平均净增重为83．88kg,显著低于（P〈0．05）添加糖蜜的Tr2、Tr3和Tr4,各试验组中以Tr3添加糖蜜2kg,净增重效果最好,为119．83kg,显著高于试验各组;同样添加糖蜜的各组ADG与对照组比较差异显著（P〈0．05）,Trl为0．92kg,显著低于（P〈0．05）添加糖蜜的各组。[结论]表明添加2kg糖蜜的Tr3肉牛的增重效果好而经济,头均比Tr1增收入556．67元。

| Abstract: | [Objective]The dosage of Molasses was discussed during the fatten period. [Method]48 cattle were randomly selected from 120 Simmental crossbreeding, which were divided into 8 groups, 6 cattle per group. The experiments were designed 4 treatment and 2 replications. Treatment （Tr.） 1 fed the corn silage and concentrates feed which was as a control. Tr2 ： Tr1＋ 1 kg/h/d molasses, Tr2 = Tr1＋2 kg/h/d molasses, Tr3 = Tr1 ＋ 3 kg/h/d molasses. The trail period was 100 days including 10 d pre- test period and 90d positive trial period. The cattle were weighed each 30 d in the morning at limosis time. The data were analyzed by SAS software. [Result] The results showed that the live weight gain （LWG） was different between fed molasses group and the treatment groups（ P 〈0.05）. The live weight gain of Trl group was 83.88 kg which was much lower than that of Tr2, Tr3 and Tr4 （ P〈0.05）. The LWG was 119.83 kg of Tr3 that fed 2 kg molasses which were the best treatment and much higher than other groups＇. The average daily gain （ADG） of fed molasses group were higher than that of Trl（ P d0.05） , which was only 0.92 kg and was much lower （ P 〈0.05） than that of fed molasses groups. [Conclusion] The experiment indicated that the Tr3 which fed 2 kg molasses got the best fatten effect, which increased 556.67 Yuan RMB than Tr1. |
