| Summary: | Objective This research aims to explore the effects of incorporating Saccharomyces cerevisiae fermentation products (SCFP) on growth performance, nutrient digestibility, antioxidant capacity, fecal short-chain fatty acids, and microbial composition of pre-weaning calves. Methods Twenty Holstein calves, 10 days old and weighing an average of 48.63±0.91 kg, were randomly assigned to either the control group (CON) or the SCFP group, with 10 calves in each group. The CON group received only a basal diet, while the SCFP group received the starter diet supplemented with 5 g/head/d of SCFP products. The pre-trial period lasted for 5 days, followed by a main experimental period of 45 days. Results The SCFP group had significantly higher final weight, average daily gain, and feed efficiency compared to the CON group (p<0.05). Moreover, the SCFP group exhibited increased apparent digestibility of dry matter, crude protein, ether extract, acid detergent fiber, Ca, and P (p<0.05). Additionally, supplementation with SCFP led to elevated content of growth hormone, insulin-like growth factor-1, and glucagon-like peptide-1 in serum. The inclusion of SCFP also raised serum catalase content and reduced serum malondialdehyde content in pre-weaning calves. Furthermore, SCFP supplementation influenced the composition of intestinal microflora by decreasing Actinobacteriota abundance and increasing the abundance of Ruminococcus, Lachnospiraceae_AC2044_group, Parabacteroides, and Butyricimonas. Conclusion The addition of SCFP has a positive impact on the growth performance, nutrient digestibility, antioxidant capacity, and intestinal microflora composition of pre-weaning calves. |
