A New Soybean Meal Product

A new feed ingredient was developed and tested in swine studies at the University of Florida. Broiler mortalities were collected, frozen on farm and transported to a central processing facility where they were minced and blended with soybean meal. The final product was dried to a final product temperature of 120-130∞ C. The modified meal product contain between 30 and 45 percent dried broiler product. Two swine studies, one with growing pigs (9-26 kg) and the other with growing finishing pigs (27-111 kg) were fed diets containing 48 percent soybean meal or a diet containing the blended broiler-soybean meal ingredient. The broiler-soybean meal ingredient contained 50 percent crude protein and 2.9 percent lysine. The average daily gains in the growing pig experiment were similar between the two protein sources. In the growing-finishing experiment, the feed utilization values for the blended protein source was nine percent better than the soybean meal treatment, probably due to the high crude fat content (14.6 percent on a as-fed basis) for the blended protein meal. Carcass characteristics and pork quality for pigs were not affected by dietary treatment. The authors concluded that broiler mortalities could be processed and blended with soybean meal to produce a safe and nutritious protein feedstuff for pigs.
