The study investigated the effects of feeding irradiated feeds to chicken. The commercial animal feeds (Starter, Broiler and Finisher) were irradiated at varying doses of 0, 3, 6 and kGy of gamma rays and fed to chickens for 45 days. Cytogenetic analyses of somatic cells were made using bone marrow cells and only the macrochromosomes were used as basis for chromosome analysis. One hundred mitotic metaphases were enumerated from control and experimental birds. Scoring was done only on macrochromosomes for chromosome aberrations. The analysis failed to show any aberrant chromosomes due to feeding on irradiated feeds
