Effect of Genotype and Sex on Chemical Composition, Physicochemical Properties, Texture and Microstructure of Spent Broiler Breeder Meat

Marcin Wegner,
Dariusz Kokoszyński,
Joanna Żochowska-Kujawska
et al.

Abstract: The aim of this research is to compare the carcass composition and meat quality characteristics of spent Cobb 500 and Ross 308 broiler breeders. A total of 28 carcasses were evaluated—7 female and 7 male carcasses from each genotype. Dissection was performed, and the percentages of neck, wings, skin with subcutaneous fat, abdominal fat, residual components, breast and leg muscles were calculated relative to the eviscerated carcass weight. The breast and leg muscles were evaluated for their chemical composition… Show more

“…LB and LW leg muscles after laying were characterized by significantly (p < 0.05) lower lightness (L*) and higher levels of yellowness (b*) and redness (a*) compared to pectoral muscles. Our results were confirmed in previous studies [11,22,26]. In our study, the genotype of birds did not significantly affect the pH 24 value of pectoral and leg muscles.…”

“…The EC 24 value of leg muscles was higher in LB by 1.1 (mS/cm) compared to LW. The reported EC 24 results of the pectoral muscle in our study were similar to those in other works [26,30]. In contrast, in the study conducted by Biegniewska et al [30], the EC 24 of leg muscles (6.3-6.8 mS/cm) in Ross 308 at 64 weeks of age was significantly lower than the results obtained in our study (9.7-10.8 mS/cm).…”
