Morphometric comparison of carcass characteristics in Ross and Cobb Broiler Strains

Ross and Cobb are two strains of broiler chickens that desirable Conversion Ratio makes them the most appropriate broiler chickens. In this experiment to evaluate morphometric carcass characteristics (live weight, featherless carcass weight, breast weight, thigh weight, back + neck, wing, liver, heart, bursa, spleen, pancreas, proventriculus + gizzard, abdominal fat) sampling of 134 broiler chickens were taken in South Khorasan. The results showed that 12 characteristics (live weight, featherless carcass weight, breast weight, thigh weight, back + neck, wing, heart, bursa, spleen, pancreas, proventriculus + gizzard, abdominal fat) between strains (P<0.01) were significantly different. The liver weight was not significantly different. Edible organs weight mean indicated that meat production efficiency and utility in Ross strain is higher compared to Cobb strain.
