Effects of fermented palm kernel cake on growth performance, serum indices, and rumen microbiota in fattening beef cattle

The study aims to explore the effects of FPKC on the growth performance, serum indices, rumen fermentation and rumen microbiota of fattening beef cattle. A total of forty-eight angus cattle, with an average body weight of 504.50 +/- 52.45kg, were selected for this experiment and randomly allocated into four groups, with 12 replicates per group. In conclusion, dietary FPKC supplementation can improve the growth performance of fattening beef cattle, enhance their antioxidant capacity and immune function, optimize rumen fermentation, and modulate the rumen microbial community.
