Aims:
This trial was performed to investigate the effects of combined feeding of Candida utilis CICC 31170, Bacillus coagulans R11, and Lactobacillus acidophilus NCFM and a multi-enzyme complex on the growth performance, immune parameters, feed digestibility, and rumen microbiota of weaned goats.
Methods And Results:
Thirty weaned goats were randomly divided into CON, PRB, and COB groups and fed different diets. End weight and ADG increased significantly in the PRB and COB groups (P < 0.05), and ADFI increased significantly in COB (P < 0.05). On day 80, there was a significant increase in IL-10 content in PRB and COB compared to the CON (P < 0.05). Highly significant increases in rumen papilla width, epithelial cell thickness, stratum spinosum+basale thickness, and stratum corneum thickness were found in PRB and COB (P < 0.05). COB group significantly increased the gene expression of HMGCL and MCT1 in rumen epithelium (P < 0.001). The COB group had the tendency to increase the feed digestibility of dry matter and crude fat compared with the CON group (P < 0.10). The abundance of Prevotellaceae_unclassified was significantly higher in PRB (P < 0.05), and the abundance of Fibrobacteres was significantly higher in COB in comparison to those in CON (P < 0.05).
Conclusions:
The results indicate that the dietary potential probiotics and enzymes complex could modulate the growth performance, immunity, feed digestibility, and rumen microbiota in weaned goats.
