Abstract:
Hatchery waste (HW) was obtained from egg type and broiler type chicks hatcheries comprising of infertile, cracked eggs during incubation, dead-in-shells, empty shells and male chicks, from egg type hatches. The crude protein and calcium (Ca) in HW were 35.49 and 20.60%, respectively. The HW was mixed with soybean cake in the ratio of 40:60 before extrusion and extruded hatchery waste mixture (EHWM) contained crude protein and Ca contents equal to 45.49 and 8.39%, respectively and contained no microbial contaminant. It was considered safe to use it as a protein supplement. In broiler rations it might be used as a substitute for fish meal.
