摘要

ABSTRACT Differences in rumen volatile fatty acids (VFAs), microbial population and community composition between water buffalo and Jersey cows were compared to explore the effects of animal species on ruminal microbiota. Ruminally fistulated buffalo ( n ?¢????=?¢????4) and Jersey cows ( n ?¢????=?¢????4) with similar body weights were selected and provided with similar diets. After feeding for 30 days, rumen fluid was collected to quantify the ruminal VFA, and determine microbial population and community composition. Results revealed that concentrations of total VFA, acetate and propionate in buffalo were higher ( P ?¢???? > ?¢????.05), while butyrate concentration and acetate/propionate ratio were lower than those in Jersey cows ( P ?¢????
