Effects of Strain on Performance, and Age at Slaughter and Duration of Post-chilling Aging on Meat Quality Traits of Broiler

This study was conducted to investigate the effects of strain on broiler performance, and age at slaughter and post- chilling (PC) aging time on meat quality traits. A total of 500 one-day-old chicks (250 Hubbard classic and 250 Lohman) were reared under commercial conditions. Half of the broiler birds from each strain were slaughtered at 32 days and the other half at 42 days old. At each processing day, 168 carcasses were randomly selected (84 Hubbard and 84 Lohman) and divided into groups of 28 carcasses within each strain, and aged for 0, 4 and 24 h after chilling. Average weekly body weight was comparable between strains. Feed conversion ratio was higher (p
