Industrial slaughtering and its effect on the quality of chicken meat commercialized in Iasi County, Romania.

Abstract

Normal 0 21 false false false RO X-NONE X-NONE MicrosoftInternetExplorer4 Accelerated development of poultry slaughtering technology imposes continuous studies about optimization of meat quality, in terms of Commission Regulation (EU) No 93/119 (1993) and profitability. The aim of this study was to check certain aspects of meat yield and carcass meat composition in two different broiler chicken genotypes ( “COBB-500” and “ROSS-308” ). Carcass meat quality studies were carried out according to generally accepted methodologies. The slaughtering efficiency was calculated using the gravimetric data achieved at slaughter moment and at 24 hours after slaughtering. Through the rationing between trenched parts weights and carcasses weight, the proportion of these commercial products revealed a range of mean values between 77.05% (post refrigeration) and 80.03% (fresh carcasses). This study suggests that processing ability and processed product characteristics are related to the chicken type of production and slaughterhouse policy. Within the same genotype, the males produced highest breast fillet yields, while the females gave better weights for thighs and shanks. Between genotypes, the observed differences in the quality of carcasses and meat were statistically significant (p≤0.05). In the same nutritional conditions, “ROSS-308” broilers provided better slaughtering efficiency than the “COBB-500” ones.
