This study’s goal was to ascertain the impact of feed limitation on the carcass weight of male broiler chicks between the ages of 32 and 40 days prior to slaughter. 180 Pure line male broiler chicks were chosen at random, given labels, and divided into six groups. When the experimental groups were 32 days old, they began the experimental feeding schedule. Group A received unlimited food for eight days (the control group), whereas groups B and C received 120 and 60 gm/bird/day, respectively. Groups D and E gave each bird 120 or 60 grammes per day for four days, respectively, then went without food for four days. Group F was not given any food during the trial (8 days). The experimental diet was created to be nearly iso caloric-iso nitrogenous and contained sorghum, groundnut cake, broiler concentrate, calcium, salt, lysine, methionine, and premix. Measurements were made for live body weight, feed intake, mortality, carcass and non-carcass data. From 32 to 34 days of age, the final live body weight, carcass weight, and dressing percentage metrics for male broiler chicks were unaffected by the feed restriction programme. However, the meal restriction programme had an impact on net weight (growth or loss) and there was a significant difference (P 0.01) between experimental groups. The ultimate live body weight, net weight (growth or loss), and carcass weight measurements for male broilers subjected to feed restriction were the lowest from 32 to 36 days of age, and the difference was significant (P 0.01). There was no discernible difference in the percentage of experimental groups that were dressed between 32 and 36 days of age (P> 0.05). The feed restriction programme had a substantial impact on all parameters between the ages of 32 and 38 days and 32 and 40 days. It has been determined that the carcass weight of broiler chickens may be controlled using a number of feed limitation tactics, depending on producer circumstances and market demand, with an emphasis on the financial return.
