Abstract:Understanding the composition and structure of the fecal microbial community may provide insight into bacterial adaptation to dietary changes in cattle. The aim of this study was to determine relationships among the fecal microbiome, residual feed intake (RFI) and residual net energy intake (REI) with diets varying in crude protein (CP). Four Holstein lactating cows (806 ± 38 kg of BW) were randomly assigned to one of two treatments (LOW: 13.2% and BASE:16.6% CP) in a crossover design (2 periods of 18 d each).… Show more
