Male broilers were fed ad libitum a control diet and diets with 1.5% and 2.7% calcium propionate (CaP). Broiler diets were supplemented with CaP for the first 2,4,6, or 8-week intervals. After being fed CaP for the previous mentioned times the broilers received a control diet for the remainder of each period. All broilers supplemented with CaP had lower body weights (p > .01). Fat pad weight was lower in CaP treated broilers slaughtered at 8 weeks of age (p > .01). Percent carcass fat was lower in CaP treated birds (p > .01). Percent carcass fat was lower in CaP treated birds (p > .01). Percent carcass protein was higher in CaP treated birds (p > .01). Plasma glucose level was increased in CaP broilers at 4,6, and 8 weeks, whereas growth hormone levels were increased in CaP broilers at 6 and 8 weeks. In, summary the inclusion of CaP in the diet of broilers lowered body weights, carcass composition and increases levels of plasma glucose and growth hormone.
