Carcass characteristics and breast meat quality in fast-, medium- and slow-growing chickens

Popis výsledku v původním jazyce

The aim of the present study was to compare carcass characteristics and meat quality of fast (Ross 308), medium (Hubbard JA757) and slow growing (ISA Dual) chickens (n = 1 980). When the chickens reached an average live weight of 2 kg, 40 birds (males to females, 1 : 1) of each genotype were randomly selected and slaughtered for carcass analysis. Pectoralis major (PM) muscle samples were taken to determine the physical and chemical parameters of the meat quality. The fast and medium growing genotypes had higher (+3,24% and +3,84%, respectively) dressing out percentages than the slow grow ing chickens. As expected, the breast percentage significantly decreased in the order of fast growth medium growth slow growth. The abdominal fat percentage was the lowest in Ross 308 chickens, but the abdominal fat percentage in JA757 and ISA Dual chickens did not differ. For edible organs, fast and medium growing chickens had heavier hearts and livers than slow growing chickens. In contrast, ISA Dual chickens showe
