Summary
Eighty 78.1 ± 1.6 lb white-faced and brockle-faced wether and ewe lambs were used in an experiment to test the effects of soybean hulls and dried distillers grains with solubles (DDGS) on growth, feed efficiency and carcass merit. Lambs were placed on test between 79 to 105 days of age (average 92 days) and fed the experimental diets for 60 days. Each pen consisted of 10 lambs. Diets were formulated to meet or exceed NRC requirements. The diets were corn or soybean hull based and DDGS served as the protein supplement in both diets. No treatment differences were observed in lamb growth at monthly intervals or for the entire period (0.77 vs. 0.79 lb/d, corn vs. soybean hull, respectively). Feed intake (DI) and feed efficiency (F/G) was greater for the soybean hull versus corn based diets (DI: 4.9 vs. 4.1 lb; F/G: 6.7 vs. 5.1 lb, respectively). Self-feeders were cleaned as needed and feed refusals were recorded. Additionally, for a 3-week period during the feeding trial, weekly feed refusals were recorded. The soybean hull diet had significantly less feed refusal per pen than the corn diet (13.9 vs. 29.1 lb/wk). Carcass measurements for back fat, loin eye area, body wall thickness, hot carcass weight, and USDA Quality and Yield Grades did not differ between treatments. No death loss occurred during the trial. These data suggest that soybean hulls are a suitable replacement for corn in finishing lamb diets.
