摘要
32头犊牛随机分为4组,分别投喂添加喹赛多0(对照)、25、50和100 mg/kg的饲料,观测不同剂量的喹赛多对犊牛生长性能及血清生化指标的影响。结果表明:添加喹赛多25、50和100 mg/kg组犊牛的平均日增重分别比对照组提高8.4%、15.2%和9.3%,犊牛的腹泻频率分别降低55.6%、66.7%和55.6%;喹赛多对犊牛的血清生化指标无显著影响。可见,饲料中适宜添加喹赛多(50 mg/kg),对犊牛有较好的促生长作用。
In order to investigate growth promotion of cyadox and its effects on serum biochemical elements in calves, 32 goats were randomly allotted to one of 4 groups which were fed with the basal diet supplemented with 0 mg/kg, 25 mg/kg, 50 mg/kg and 100 mg/kg cyadox, respectively, for 45 d. The results showed that 25 mg/kg, 50 mg/kg and 100 mg/kg of cyadox improved average daily gain by 8.4 %, 15. 2%and 9.3%,and reduced diarrhea frequency by 55. 6% ,66. 7% and 55.6% ,respectively. It was obvious that cyadox at proper doses,especially 50 mg/kg,promoted growth efficiently.
