摘　　要：本试验采用两种消毒剂处理饮水,研究其对犊牛生长性能和腹泻发病率的影响。将出生重和出生日期相近的荷斯坦犊牛随机分成对照组、试验1组和试验2组,每组8头。试验从4日龄开始,50日龄结束;对照组直接饮用地下水,试验1组饮用复合碘伏溶液处理后的地下水,试验2组饮用聚六亚甲基双胍和过氧化氢处理后的地下水。试验结果:对照组、试验1组、试验2组出生至50日龄日增重依次为(495.60±96.02)g/d、(466.34±110.52)g/d和(522.63±106.32)g/d,3组间差异不显著(P>0.05);对照组、试验1组、试验2组腹泻频率依次为(6.18±6.08)%、(5.78±3.72)%和(4.26±3.32)%,3组间差异不显著(P>0.05);对照组、试验1组、试验2组粪便指数依次为(1.70±0.68)、(1.65±0.72)和(1.60±0.66),3组间差异不显著(P>0.05)。在本试验条件下,两种饮水消毒剂处理饮水对犊牛生长性能和腹泻发病率的影响不显著。Treatments of drinking water with two kinds of disinfectant on growth and diarrhea rate in calves were studied.. Twenty-four Holstein female calves were randomly divided into 3 group （8 for each group） based on body weight and birth similarity. Control groupfed well water; experimental group 1 fed well water treated with compound iodine solution and group 2 fed well water treated with poly hexamethylenebiguanide and hydrogen peroxide. The experiment began when calf was born and ended when 50 days old. Result showed that the average daily gain （ADG） of calves were （495.60±96.02） g/d, （466.34±110.52） g/d and （522.63±106.32） g/d for control ,group 1 and group 2 respectively ; diarrhea rate for control, group 1 and group 2 were 6.18±6.08%, 5.78＋3.72% and 4.26±3.32% respectively; feces score of calves werel.70±0.68, 1.65±0.72 and 1.60±0.66 for control, group 1 and group 2 respectively. There were no significant differences （P〉0.05） among three groups neither in daily gain nor in diarrhea rate and feces scores .The experiments indicated that the water sterilized by disinfectants had no influence on growth and diarrhea rate in calves.
