Effect of radiation processing as an integral part of the safe recycling animal waste

Recycling animal waste as a feedstuff could have a considerable effect on reducing costs and solving some disposal problems. Although the technology of animal waste handling, treatment and disposal is available in many cases it is not adequate to guarantee a pathogen-free end product. However, radiation processing can make an important contribution to solve these problems. Effects of radiation processing, on crude and true protein, amino acid profile, minerals and thiamine content of dried broiler and cow manure, at dose levels of 5, 10 and 25 kGy have been studied. Short-term feeding tests were carried out to determine the effect of radiation pasteurization of such animal waste on growth performance of young chicks. The results suggested that radiation pasteurization of dried manure has a beneficial effect on recycling of such waste and it permits waste to be included in animal diet without nutritional problems.
