Performance and changes in body composition of broiler chickens depending on feeding regime and sex
Original language description
The aim of this study was to evaluate the differences in the performance, carcass parts and internal organs of broiler chicken females and males fed ad libitum or restricted by 80 and 65 % ad libitum. Ross 308 males and females (2430 chickens) were fed ad libitum (ADL) or were restricted between the 8th and 14th days of age by 80 % ADL (R1) and 65 % ADL (R2), respectively. Feed restriction depressed the live weight in both sexes. Both sexes compensated for growth, and at the end of the fattening at 35 days, restricted males (-3 % R1 and -6 % R2) and females (-3 % R1 and -4 % R2) were not significantly lighter than the ADL chickens. Feed intake was lower in females than in males, and feed restriction and sex did not affect the feed conversion ratio. The growth of internal organs as early-developing tissues (heart, gizzard, liver) was less affected than the growth of late- developing tissues (breast, thigh, abdominal fat). Restricted males and females had more abdominal fat than the ad libitum chicke
