Effects of Fermented Chinese Herbal Medicines on Production Performance, Serum Biochemistry and Rumen Microbiota in Early Lactation Dairy Cows

This study aims to investigate the effects of fermented Chinese herbal medicines (FCHM) on lactation performance, rumen fermentation, and microbial ecology in early lactation dairy cows, with a focus on clarifying how FCHM modulates digestive function and immune status. Its relevance lies in addressing the challenge of low feed efficiency and high inflammation risk in early lactation, a critical period when cows face severe metabolic stress. By evaluating the impacts of FCHM on production indices, antioxidant parameters, and rumen microbiota, this research provides theoretical support for developing natural feed additives to improve dairy cow health and productivity, which is of practical significance for sustainable livestock farming.
