Abstract:
Background and Objective: Noi is classified as a medium and slow-growing chicken breed of Vietnam, mainly for meat quality and fighting. This study aimed to evaluate carcass performances of Noi broilers at 91 days old. Materials and Methods: A total of 355 Noi chickens (164 males and 191 females) were slaughtered at the time point of 91 days old to record and calculate cut-up traits of the carcass. Results: Most of the evaluated traits were significantly different (p<0.001) between genders. Particularly, the males were always heavier than the females in weights of live body, carcass, thigh meat, breast meat, wing and drumstick (p<0.05),where as abdominal fat displayed a contrast between genders (25.04 g for males and 24.74 g for females) although no significant difference was found for this trait (p>0.05). In addition, genders significantly affected some cut-up portions such as live weight and carcass weight, except differences in weights of breast yield and abdominal fat, which was found in contrast. Live weight, in overall, significantly correlated with most carcass traits (p<0.001), but the coefficients differed due to the type of the observed traits. Females were higher in correlation to the weight of breast, thigh and drumstick than males (r = 0.71-0.88; r = 0.82-0.91, respectively). Conclusion: The findings showed that Noi male broilers had better performances in the live weight and carcass parameter than the female ones, suggesting opportunities for management and genetic improvement through the selection and cross-breeding of the indigenous chicken population.
