| 摘 要： | 将45头去势荷斯坦公牛随机分成三组,对照组(I组)饲喂只含豆粕的精料,试验II组饲喂含膨化棉籽(EC)替代50%豆粕日粮,试验III组饲喂含EC完全替代豆粕的日粮。结果表明,三组供试牛的精料消耗量、末重及日增重均无显著差异(P>0.05)。经济效益分析表明,就本场规模而言(300头),试验II组的生产成本比第I组减少0.44元/头.日,每年可节约精料费用48 180元;试验III组的生产成本比对照组减少0.94元/头.日,每年可节约精料费用102930元。

| Abstract: | Forty-five Holstein steer were randomly divided into three groups.Concentrate of group I only contained soybean meal,concentrate of group II contained 1/2 expanding cottonseed and 1/2 soybean meal and concentrate of group III only contained expanding cottonseed.The results showed that there were no significant differences(P>0.05) of concentrate consumption,final weight and daily gain among three groups.The analysis of economic benefits was listed as follows: as far as the scale of the beef cattle farm(300 fattening cattle) was concerned,feeding production cost of group II than group I reduced by $ 0.44 per cattle a day,and that of the group III at the level of $ 0.94 per cattle a day. The concentrate cost of the II group and group III was saved $ 48 180 and $ 102 930 per year,respectively. |
