Abstract: An experiment was conducted to assess carcass characteristics and offals of broilers fed on varying forms of feeding regimes. 240, 1-day old broiler chicks-were randomly allotted to four feeding regimes each in 6 replicates of 10 birds per replicate designated as treatments as follows: ad libitum, twice a day split feeding, thrice a day split feeding and 3 hours restriction feeding. Birds were slaughtered on day 42 to determine the relative weights of the primal cuts and visceral organs. Significant differences (P<0.05) were obtained on carcass parameters' measured. Birds on ad libitum feeding had the highest bled (87.6), dressed (61.9), eviscerated (67.0) and de-feathered weights (82.5%) while the least values were obtained from birds fed thrice a day, though the values were not significantly different (P>0.05) from those of birds on twice a day split feeding regime. Birds fed ad-libitum had the highest drumstick weight (8.84%) and wing percentages (6.73%). The neck percentages were 4.47, 4.22, 3.04 and 2.84 for ad-libitum, twice a day, 3 hour restriction and thrice a day feeding respectively. Liver, abdominal and crop weights were similar (P>0.05) for ad libitum and twice feeding regime but were different (P<0.05) from thrice and restricted feeding regime. Broilers on ad libitum and twice a day feeding regimes gave the best results for carcass, primal cuts and organ weights measured.
