Abstract

Thirty calves were used in an 84-day growth trial to evaluate protein efficiency of corn steep compared to soybean meal. Calves were individually fed a base diet supplemented with either 1) urea, 2) soybean meal, or 3) corn steep. Soybean meal and corn steep were fed at graded levels replacing urea. In vitro ammonia release analyses showed the protein in both corn steep and soybean meal to be approximately 30% undegradable in the rumen. Calves fed corn steep had similar protein efficiency to calves fed soybean meal, supporting the in vitro data.
