Özet

A total of 211 pheasants (Phasimus colchicus) were reared using two different production systems (free range and intensive) to determine the effect of production system and slaughter age on growth performance and carcass traits. Birds were slaughtered at 14, 16, and 18 weeks of age. Production system did not significantly affect body weight until 18 weeks; at this age, pheasants reared in free range exhibited a higher average weight (1149 g vs. 1012 g). Total feed consumption and feed conversion ratios did not differ among production systems. The most in-demand portions of the carcass (breast and leg) were not affected by differences in production system. The leg and breast proportions which were the most edible parts of the carcass were around 26% and 35%, respectively, in both free-range and intensive systems.
