不同酵母菌制剂对断奶羔羊的临床应用效果研究

Study on the Clinical Application Effects of Different Yeast Preparations on Weaned Lambs

[目的]分析临床常用酵母菌制剂对断奶羔羊生长性能及抗腹泻能力的影响,筛选增免促长有效药物。[方法]选取体重相近的断奶羔羊40只,随机分为4组,即3个试验组和1个对照组,通过拌料方式分别在日粮中添加福邦酵母、百利可和增速乐,正常饲喂,连续用药30 d,对各组羔羊的平均日增重、血液生理生化指标进行测定,并对各组羔羊腹泻率进行统计。[结果]福邦酵母组断奶羔羊的平均日增重最高,与对照组差异极显著(P<0.01);福邦酵母组断奶羔羊的白细胞数目与红细胞数目均高于其他组,且与对照组差异均极显著(P<0.01);福邦酵母组谷丙转氨酶(ALT)最高,与其他组差异极显著(P<0.01);福邦酵母组白蛋白(ALB)与百利可组和对照组差异显著(P<0.05);福邦酵母组和百利可组的葡萄糖(GLU)均与增速乐组和对照组差异极显著(P<0.01);对各组断奶羔羊抗腹泻能力的检测发现,福邦酵母组断奶羔羊腹泻率最低。[结论]3种药物中福邦酵母在羔羊增免促长方面有较好的应用效果。

[Objective] To analyze the effects of commonly-used yeast preparations on the growth performance and anti-diarrhea ability of weaned lambs,and screen out effective drugs with growth-promoting and immunity-enhancing effects.[Method] 40 weaned lambs with similar body-weight were randomly divided into 4 groups,including 1 control group and 3 test group.Fubang yeast,Bailike and Zengsule were added in the diet by mixing with the diet.The weaned lambs was conducted with normal feeding and continuous drug administration for 30 days.The average daily weight gain,blood physiological,biochemical indices of weaned lambs in each group were measured,the diarrhea rate of each group was counted.[Result] The average daily weight gain of weaned lambs in each group in Fubang yeast group was the highest,which had extremely significant difference with that in control group( P <0.01).The number of white blood cells and red blood cell (RBC) in Fubang yeast group were higher than those in other groups,which had extremely significant difference with those in control group( P <0.01). The alanine aminotransferase (ALT) in Fubang yeast group was the highest ,which had extremely significant difference with other groups ( P <0.01).The albumin (ALB) in Fubang yeast group had significant difference with that in Bailey group and control group (P< 0.05).The glucose (GLU) in Fubang yeast group and bailey group had significantly difference with that in Zengsule group and control group ( P< 0.01).The anti-diarrhea ability test showed that the diarrhea rate in Fubang yeast group was the lowest.[Conclusion] Fubang yeast had a good application effect for promoting the growth and increasing the immunity of weaned lambs among the three drugs.
