摘 要:为了研究冬季卧床垫草对西门塔尔育成公牛增重效果的影响,试验选择同一胎次的6月龄左右体重相近的西门塔尔育成公牛40头,随机分为试验组和对照组,试验组卧床采用粉碎玉米干秸秆作为垫草,对照组卧床为水泥地面,试验期为70 d。结果表明:与对照组比较,试验组04:00时氨气浓度降低31. 82%,育成公牛的平均日增重增加0. 099 kg,提高8. 36%,日效益提高1. 93元,利润提高11. 53%。说明冬季卧床垫草对肉牛养殖效益增值空间很大。In order to study the effect of mat grass on the weight gain of breeding Simmental bull in winter,40 6-month-old breeding Simmental bulls with similar weights and the same parity,were chosen in this experiment,which were randomly divided into experimental group and control group. The experimental group used crushing corn dry straw as mat grass,while the control group used the cement floor only. The experimental period was 70 days. The results showed that compared with the control group,ammonia concentration decreased 31. 82% at 4 o’clock in the experimental group. Average daily weight gain in the experimental group was 0. 099 kg more and increased 8. 36% than that in the control group.The daily benefit was 1. 92 yuan higher and increased 11. 53% in profit than that in the control group. The results suggested that mat grass on cow bed in winter has a great value-added space for beef cattle breeding.
