Abstract


Search mechanisms that can reduce the cost of production of poultry is an important factor in the poultry industry. Thus the objective of this study was to evaluate the removal of vitamin and mineral supplement or limestone and dicalcium phosphate feed during the finishing phase, further of the broilers chickens to heat stress pre-slaughter. Hybro male broiler (n=108) aged 42 days old were evaluated until 49 days old to evaluate the performance, carcass and cuts yield, blood biochemistry and meat quality. The results showed that the removal of vitamin and mineral supplement or limestone and dicalcium phosphate feed during the finishing phase did not impair the performance, carcass characteristics and meat quality, as well as showing a possible mechanism to reduce production costs. While heat stress pre-slaughter provided a poor meat quality of poultry.
