摘要：
The present study was carried out to compare the growth performance and carcass yield of broiler chickens reared in semi-intensive and conventional systems (Ross 308, n=120). Chickens were raised in a pen on wooden shavings for 21 days. On day 21 of age, chicks were assigned to 2 treatments (indoor treatment and semi-intensive treatment). The experiment was conducted at until 6 weeks of age. Production system has a significant effect on wing (P<0.05) and heart weight (P<0.01), but has no any effect on final body weight, hot or cold carcass weight, thigh, breast, back and neck, gizzard, liver and abdominal fat weights (P>0.05). The final body weight, hot and cold carcass weight, thigh, wings and heart weights were affected by sex of birds (p<0.05) while breast, back, liver, gizzard and abdominal fat were not affected by sex (P>0.05). The nutrient level of carcass parts was not influenced by production system or sex (P>0.05). In our study, breast of birds reared under semi-intensive system had significantly lower 'L' (P<0.05), higher 'a' statistically different (P<0.01); while 'b' value was significantly (P<0.01) higher in skin of semi-intensive reared birds.
