Abstract
The present study was conducted to provide basic information on differences in meat quality traits of different breeds of poultry i.e. White Lcghorn, White plymouth Rock and Lyallpur Silver Black and rural chicken at 12 weeks and spent layer age. The results indicated that age had a non-significant effect on crude protein content of muscles. The significant differences were observed between various breeds. The age also had no effect on ether extract but significant differences due to breed and location were observed. The age and breed affected significantly but location had no effect on ash content of muscle tissues. The chemical score for meat protein of Dcsi, Lyallpur Silver Black, White Plymouth Rock and White Leghorn was 13.00, 23.00, 18.66 and 23.33% respectively. The thigh and breast muscles of Dcsi breed had the lowest calcium content of all the breeds.
