The effect of composite probiotics on biochemical indicators and immune performance of beef cattle
In order to study the effects of probiotic composite on the growth performance,meat quality and immune performance of beef cattle,the experiment was designed as a one-way randomized trial,and Thirty healthy Belgian Blue Cattle of 12 months of age and weighing(400±20.05)kg were selected as test animals.The straight animals were randomly divided into 3 groups,test group 1 was the control group,and test groups 2 and 3 were the experimental groups.Five replicates of three cows each were conducted,with all three groups fed a basal diet for concentrates;test groups 2 and 3 were additionally supplemented with 200 mg/kg and 400 mg/kg of probiotic complex in the basal diet,respectively.The results showed that the addition of 400 mg/kg of probiotic complex in group 3 significantly increased the growth performance,meat quality and immune performance of beef cattle(P＜0.05).The addition of 200 mg/kg of probiotic complex in the test 2 groups improved the growth performance,meat quality and immune performance of beef cattle,but the differences were not significant(P＞0.05).In conclusion,the addition of different levels of compound probiotics can effectively improve the growth performance,meat quality and immune performance of beef cattle.It is recommended to add 400 mg/kg of compound probiotics with lactic acid Enterococcus faecalis:Saccharomyces cerevisiae:Bacillus cerevisiae(2∶2∶1)and total viable bacterial count≥1.3×1011 CFU/g in beef cattle feeding process.
