益生菌制剂对犊牛生长性能、血清生化指标及养分消化率的影响
Effects of Probiotic Preparation(PP)on growth performance,serum biochemical parameters,and nutrient digestibility in calves
摘要
Abstract
This study aimed to investigate the effects of PP on growth performance,serum biochemical parameters,and nutrient digestibility in calves.The experiment selected 75 healthy 1-day-old Holstein calves.The calves were randomly assigned to 5 groups×3 replicates×5 calves.The control group(CON)received milk replacer+starter feed,while the 4 experiment groups received milk replacer+starter feed+500,1000,1500,2000 mg/kg PP,designated as PP500,PP1000,PP1500,PP2000 groups.The trial lasted 60 days.Results:1)During 31-60 days old,compared with CON group,the calves'ADG of PP1500,PP2000 groups significantly increased by 9.81％,10.28％(P<0.05),and the calves'FCR of PP1500,PP2000 group significantly decreased by 7.79％,8.41％(P<0.05).During 31-60 day-old,the calves ADG of PP500,PP1000 group was lower than PP1500,PP2000 group(P>0.05),and the calves'FCR was higher than PP1500,PP2000 groups(P>0.05).2)Compared with CON group,the calves'serum total protein,albumin in the PP500,PP1000,PP1500,PP2000 groups significantly increased(P<0.05),and the calves'serum urea nitrogen in the PP2000 group significantly decreased(P<0.05).There were no significant differences in the calves serum total protein,albumin,urea nitrogen of PP500,PP1000,PP1500,PP2000 group(P>0.05).The calves'serum glucose of PP1500,PP2000 groups was significantly higher than CON,PP500 groups(P<0.05).There were no significant differences in the calves serum glucose of PP1500,PP2000 group(P>0.05).3)Compared with CON group,the dry matter digestibility of PP1500,PP2000 groups was significantly increased(P<0.05),and the crude protein digestibility of PP500,PP1000,PP1500,PP2000 groups was significantly increased(P<0.05).There were no significant differences in the calves dry matter,crude protein digestibility of PP500,PP1000,PP1500,PP2000 group(P>0.05).In conclusion,PP can improve growth performance,metabolic function,and nutrient digestibility in calves.Under the conditions of this experiment,the recommended supplemental dosage of PP is 1500 mg/kg.关键词
