502 _aThe presented study was conducted at control house of Department of Poultry Production, C-block, UVAS Ravi Campus. In total 480, day-old Hubbard Classic broiler chicks were procured from local hatchery, weighed at 1st day and randomly distributed to eight treatment groups in such a way that there were six replicates in each group and each replicate had 10 chicks. Eight isocaloric and isonitrogenous experimental diets were formulated. Half birds were offered crumble form of feed in whole life while half birds were offered crumble form in starter phase and pellet form in finisher phase. Four levels (<1, 1-1.5, 1.5-2 and 2-2.5mm) of corn particle size were used in each form of feed.Body weight and feed consumptionwere recorded weekly in order to calculate feed conversion ratio.Data collected were analyzed by ANOVA using factorial arrangement under CRD. Experimental means were compared using DMR test. Birds fed diet having higher particle size (2-2.5mm) of corn had lower feed consumption, greater body weight gain and improved FCR compared to those fed smaller particle size during starter, finisher and overall phase. Further, birds fed pelleted feed had lower feed consumption, greater weight gain and improved FCR than those fed crumble form of feed.Further, different particle size of corn resulted in non-significant effect on villus height and crypt depth. Feed form also had non-significant influence on villus height and crypt depth of duodenum.Birds fed diet having higher particle size (2-2.5mm) of corn had higher apparent ileal digestibilityof protein than those fed smaller particle size. Feed form had non-significant effect on apparent ileal digestibilityof protein. It can be concluded from the results that birds fed pelleted diet containing coarse particle size had improved growth performance and protein digestibility without adverse effect on gut health of broiler.
