Effects of yeast hydrolysate on mental status,serum biochemical indexes,and intestinal flora of lactating calves
摘要
Abstract
The experiment was conducted to study the effects of yeast hydrolysate on the mental status,serum biochemical indexes,and intestinal flora of calves.A total of 30 one-day-old Holstein female calves with body weight(39±2)kg were selected and randomly divided into a control group and experimental group(supplemented with 5 g/(head·d)yeast hydrolysate),with 15 replicates in each group and one calf in each replicate.Pre-trial period is seven days,and the formal trial period is 56 days.The results showed that the supplementation of 5 g/(head·d)yeast hydrolysate could improve the mental status,fur state and fecal scores of calves.On the 63 days,compared with the control group,the activities of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and the concentrations of total protein(TP),albumin(ALB),globulin(GLB),blood glucose(GLU),urea nitrogen(BUN)and cholesterol(TC)in serum of calves in experimental group were significantly increased(P＜0.05).On the 35 days,the Chaol and Observed-species indices of fecal microbiota in the experimental group were significantly reduced(P＜0.05).Compared with the microbial genus level,the abundance of Faecalibacterium in fecal flora increased on the 14th day.The richness of Faecalibacterium in the fecal flora decreased on the 35th day.The results show that supplementation of 5 g/(head d)yeast hydrolysate can improve the mental state,fur state and feces of calves,improve the serum biochemical indexes,increase the abundance of intestinal beneficial flora,and promote the healthy growth of calves.关键词
