Growth and slaughtering performance, carcase fleshiness and meat quality according to the plumage colour in Padovana male chickens slaughtered at 18 weeks of age

AbstractThe aim of this trial was to investigate on the growth and meat quality of Padovana male chickens with different plumage varieties, chamois (PC - light brown feathers with white edge), silver (PS - white feathers with black edge), and their cross. The body weight of PC during the growth period was higher (p < .01) than PS, and it was 1.7 and 1.5 kg, respectively, at 126 d of age. At slaughter, PC showed higher weight of carcase (p < .05), breast and total fleshiness (breast, wings and legs) (p < .01), and thigh meat:bone ratio (p < .05). PS showed higher shanks weight on carcase weight (p < .01), Ilio tibialis a* value (p < .01), water losses (p < .01) and shear force (p < .05) in breast meat than PC. Crossing PC males to PS females gave birds with white (Cross-W) and silver (Cross-S) plumage (3:1 ratio, respectively). The offspring genotypes showed similar body weight, and almost all slaughtering, carcase and meat quality traits studied. Cross-W and Cross-S showed significantly higher final body ...
