Sixty individually fed heifers were used in an 84-day growing trial to determine effects of adding rumen protected methionine and/or bloodmeal on performance of growing heifers supplemented with Soypass®. Treatments were designed to be a 2x2 factorial with diets supplemented with or without rumen protected methionine and bloodmeal (0.3% of DM) to provide 0.72 g per day of additional histidine as factors. The rumen protected methionine source, Smartamine M®, provided 1.85 g per day of additional methionine. No statistical differences in performance among treatments were observed, suggesting growing animals fed Soypass® do not benefit from addition of supplemental rumen protected methionine or bloodmeal.
