A,B,CValues in rows with different letters show significant results (). Growth rate (%) was calculated using the following formula: , with BWi as the initial body weight of the rearing period (g) and BWf as the final body weight of the rearing period (g). Percentage of breast muscles, leg muscles, and abdominal fat of carcass was calculated in relation to the weight of the chilled carcass with giblets. ADG was measured as (BW on 21st day − BW on 14th day)/7 and (BW on 42nd day − BW on 35th day)/7.
