Istraživanje svojstava tovnosti i kvalitete mesa provedeno je na 120 pilića hibrida Ross 308 i Cobb 500 s ciljem da se utvrdi utjecaj genetske osnove i spola, kao i njihova interakcija. Utvrđen je statistički visoko značajan (P0,05) utjecaj hibrida pilića na žive mase po tjednima tova. Muški pilići imali su statistički visoko značajno (P<0,001) teže: trupove, prsa, batake sa zabatacima, krila i leđa u odnosu na ženske piliće. Utvrđen je statistički značajno (P<0,05) ve_i udio mišića bataka i zabataka u trupu kod muških u odnosu na ženske piliće. Ženski pilići imali su statistički značajno veći (P<0,05) udio kože u trupu od muških pilića. Ross 308 pilići imali su statistički značajno (P<0,05) veći udio prsa u
trupu u odnosu na Cobb 500 piliće. U prsnom mesu muških pilića utvrđena je veća vrijednost pH1 izmjerena unutar 45 minuta nakon klanja (P0.05) of chicken hybrids was determined on live weights. At a statistical significance level of P<0.001, male chickens had heavier carcasses, breasts, thighs with drumsticks, wings and backs than female chickens. In comparison to females, statistically significantly (P<0.05) higher portion of thighs and drumsticks in carcass was determined in male chickens. Female chickens had significantly higher (P<0.05) portion of skin with subcutaneous fatty tissue in carcass than male chickens. Ross 308 chickens had significantly (P<0.05) higher portion of breasts in carcass than Cobb 500 chickens. Higher value of pH1 measured within 45 minutes post slaughtering (P<0.01), as well as higher values of pH2 and electric conductivity measured 24 hours post slaughtering (P<0.01) were determined in breast muscles of male carcasses. Cobb 500 chickens had statistically significantly lower (P<0.05) pH2 value than Ross 308 chickens. It was established statistically highly significant effect (P<0.001) of chicken hybrids on the measured L* values, while chicken gender statistically significantly (P<0.05) affected the *a and *b values
