Utilization of infertile eggs in geese

　　The solid hatchery waste comprises empty shells, infertile eggs, dead embryos, late hatchings and dead chickens and a viscous liquid from eggs and decaying tissue. The high cost of imported feed ingredients, such as fish meal, methionine, lysine etc., has necessitated the use of unconventional feedstuffs as replacement for the conventional ones. The protein content of waste egg power product with eggshell or nil were 23.8% and 25.7%, respectively. Products cost with eggshell or nil were 8.04 and 10.1 NTD/kg.
