The present study was conducted to investigate the effects of different dietary proteins as fraction-enriched protein, defined by Cornell net carbohydrates and protein system (CNCPS), on in vivo ruminal fermentation pattern and blood metabolites in Holstein steers fed total mixed ration (TMR) containing 17.2% crude protein. Four ruminally cannulated Holstein steers in a 4 × 4 Latin square design consumed TMR only (control) and TMR with rapeseed meal (AB1), soybean meal (B2), and perilla meal (B3C). Each protein was substituted for 23.0% of crude protein in TMR. Rumen digesta were taken through ruminal cannula at 1 h interval during the feeding cycle in order to analyze ruminal pH, ammonia-N, and volatile fatty acids (VFA). Plasma metabolites in blood taken via the jugular vein after the rumen digesta sampling were analyzed. Feeding perilla meal significantly (p < 0.05) decreased mean ruminal pH compared with control and the other protein feeding groups. Compared with control, feeding protein significantly (p < 0.05) increased ruminal ammonia-N concentration except for AB1. Statistically (p > 0.05) similar total VFA appeared among control and the supplemented groups. However, control, AB1, and B2 showed higher (p < 0.05) acetate concentrations than B3C, and propionate was vice versa. CNCPS fractionated protein significantly (p < 0.05) affected concentrations of albumin and total protein in blood; i.e. plasma albumin was lower for control and B2 groups than AB1 and B3C groups. Despite lack of significances (p > 0.05) in creatinine and blood urea nitrogen, AB1 and B2 groups were numerically higher than the others.
