Evaluation of Dried Bakery Products for Use in Broiler Diets

DRIED bakery product (DBP)* has only recently become available in commercial quantities for animal feeding, and very little research has been conducted on its use. Morrison (1959) reported that bakery wastes could be used in place of part of the grain usually fed. Since bread is about 30% water, the waste’s feeding value is only 75% of corn or other grain. Morrison indicated that kiln-dried bakery waste is similar to grain in composition, except it is lower in fiber and may be higher in fat. Grimes (1927) found that kiln-dried stale bread, moistened with water, was almost equal to corn when fed to pigs on pasture, but was constipating unless fed with some laxative feed. Stale crackers were somewhat less valuable. Combs et al. (1965) conducted an experiment to determine the feasibility of substituting 5, 10, 15 or 20% of DBP for equal amounts of dried skim milk in the…
