effect of gamma irradiation on the chemical compounds and microbial load of broilers diet

the aim of this study was to determine and scrutiny about chemical compounds and microbial load changes of broiler chicks’ diet due to gamma irradiation processing. there were 12 broiler chicks’ diets weighting one kg that including 4 packs from starter period, 4 packs from grower period and 4 packs from finisher period. feeds were irradiated in four doses including 0, 6.7, 7.7 and 8.7 kilogray. according one-way anova analysis, data sets of proximate chemical compounds changes comprising peroxide value, ether extract and crude fiber indicates that there was significant (05/0≥p) deference between irradiated and control groups. nonetheless, chemical changes for crude protein and ash were venial. all of the irradiated diets indicated that there were no bacterial colony on the related media.
