چکیده
This study aims to compare anatomies of Madagascar chickens (indigenous race and Starbro strain). With 8,262 individuals of either indigenous races or Starbro strain chickens raised in a suburban environment, the weights of different pieces of cut as well as the live weights before slaughter were determined. Results showed that breast development presents a positive linear relationship with thigh development for Starbro strain chickens (fast growing broiler) while the relationship between the two traits is negative for the indigenous races (slow growing chicken). Giblet proportions are similar between these two types of chicken. We found that slaughtering at 1,750g live weight (age 120 to 185 days) is profitable for indigenous race chickens (meat yield = 40.16%, breast yield = 18.10%, thigh yield = 20.15% and abdominal fat yield = 1.90%). For the Starbro strain, ideal weight at slaughter is 1,300-1,450 g, corresponding to 49 to 61 days of age (meat yield = 39.63%, breast yield = 17.85%, thigh yield = 20.27% and abdominal fat yield = 1.51%). The physical features of the cuts are similar between indigenous races and Starbro strain chickens.
