| 摘 要： | 选取42头体重相近的荷斯坦公牛，随机分为7组，每组6头。对照组饲喂基础日粮，调控剂A1、A2、A3组在基础日粮中添加营养调控剂A，添加剂量分别为2g／（d·头）、5g／（d·头）和8g／（d·头）。调控剂B1、B2、B3组在基础日粮中添加营养调控剂B，添加剂量分别为2g／（d·头）、5g／（d·头）和8g／（d·头）。试验结果表明，调控剂A2组和调控剂B2组的平均日增重与对照组相比，分别增加了0．19kg和0．20kg，差异显著（P〈0．05）；以上两组的平均日收入与对照组相比，分别增加了3．57元和3．82元。结果表明，营养调控剂A和营养调控#IB在荷斯坦公牛日粮中添加剂量为5g／（d·头）时，可以促进公牛的增重，提高经济效益。

| Abstract: | 42 similar weight Holstein male calves were randomly divided into 7groups （n=6）. The control group was fed the basal diet, while group A and group B were fed the diets which were added the nutritional regulation additive A and B, group A1 and B1 with dosage of2g / （d · calf）, group A2 and B2 with dosage of5g / （d · calf）, group A3 and B3 with dosage of 8g / （d · calf）. The results showed that average daily gain of group A2 and group B2 increased by 0.19kg （P〈0.05） and 0.20kg （P〈0.05） respectively, as compared with the control.The average daily income of group A2 increased by 3.57 yuan （RMB）, while group B2 increased by 3.82 yuan （RMB）, as compared with the control group. The results indicated that the nutritional regulation additive A and B with the dosage of 5g / （d · calf）, can improve the effect of weight gain, increase economic efficiency. |
