hydrolyzed feather meal, corn silage, crude protein, steer calves
Hydrolyzed feather meal (HFM) was evaluated for soybean meal replacement value in corn silage diets fed t o steer calves. One hundred ninety-two steers (692 lb) were fed corn silage diets formulated to contain 11.5% crude protein. Hydrolyzed feather meal was substituted for soybean meal at levels providing 0, 25, 50 or 75% of the supplemental protein. Overall performance for the 98-day feeding trial was as follows: 2.10 lb average daily gain; 17.91 lb/day dry matter (DM) intake and 8.58 DM/gain. Protein supplements had no effect on performance, indicating that cost per unit protein is the primary consideration when formulating supplements containing HFM for growing calves fed high quality corn silage.
