Effect Of Rumen-Degradable Protein Balance Deficit On Voluntary Intake, Microbial Protein Synthesis, And Nitrogen Metabolism In Growing Double-Muscled Belgian Blue Bulls Fed Corn Silage-Based Diet

peer reviewed ; Two trials were conducted to evaluate the effect of rumen-degradable protein balance (OEB) deficit on voluntary intake (trial 1), microbial protein synthesis, andNmetabolism (trial 2) in growing doublemuscled Belgian Blue bulls. In trial 1, six bulls (339 ± 26 kg of initial BW) were used in a replicated 3 × 3 Latin square and received a diet of 60% corn silage and 40% concentrate with ad libitum intake (DM basis). Three concentrates were formulated by adding urea at the expense of barley to give similar dietary contents of intestinal digestible proteins, NE for fattening, and f... Mehr ...
