Mortalities in turkey, broiler and layer operations currently are treated as a waste product, with cost of disposal borne by the poultry producer. These geographical features cause increased concern about animal waste disposal.
Burial is inadvisable.
Composting waste and then spreading it as fertilizer causes concern about nitrogen application levels. The use of poultry mortalities as a source of supplemental protein and energy in livestock feeds addresses both of the above concerns. Using mortalities as a feed source has the potential to reduce disposal costs and increase producers' net income. Re-cycling this waste product provides an opportunity to decrease the total waste stream being applied to the land resource. The experimental design was a randomized complete block design with age, sex, and initial weight used as blocking factors.
