The objective of this trial was to evaluate three different concentrate levels (CL) (23, 43 and 63%) on intake, nutrient digestibility, ruminal metabolism, and microbial efficiency in Holstein bovines and Murrah buffaloes (Bubalus bubalis) fed diets containing ground corn and dry cassava by-product as energy sources. Three Holstein bovines and three Murrah buffaloes averaging, respectively, 473±54 kg and 400±33 kg of body weight (BW), fitted with ruminal and duodenal cannulas were blocked by species and randomly assigned to two replicated […]
