| Title : | DIFFERENCE IN THE CARCASS QUALITY AND MEAT CHEMICAL COMPOSITION IN TWO LINES OF SLOW-GROWING CHICKENS WITH OR WITHOUT ACCESS TO PASTURE |
| Abstract : | The study was carried out to compare the carcass quality and the chemical composition of breast and thigh meat in two lines of slow-growing male chickens - La Belle (LB) and Bresse Gauloise (BB) reared conventionally or outdoors, having access to pasture. The birds were slaughtered at 12 weeks of age. Two-way ANOVA was used to assess the effect of the rearing strategies as well as the line on the carcass quality and meat chemical composition. Rearing system affected significantly the carcass traits of the birds. The lines reared on pasture had lower live and carcass weight as well as lower dressing percentage (P<0.001). On the other hand they had higher percent (P<0.001) of the edible by-products (neck and giblets). The percentage of the breast meat was significantly reduced in the birds that had access to pasture (P<0.001), while thigh remained unaffected. The pastured chickens displayed higher part of the wings (P<0.01). Outdoors rearing influenced the chemical composition in the breast and thigh meat of the lines. Chickens reared on pasture were characterised by lower lipid content (P<0.01) in breast and reduced protein in thigh (P<0.05), as well as increased moisture in both kinds of meat, however depending on the line (P<0.05). Furthermore, pasture access resulted in reduced ash content of the breast meat (P<0.001), which was lower in the LB chickens (P<0.01), while in thigh this parameter was strongly determined by the interaction of the rearing system and line of the birds (P<0.01). |
