The purpose of this study was to evaluatethe effect of the kind of light programme on slaughter and meat yield, as well as on physicochemical and sensory traits of breast and leg muscles in Ross 308 and Hybro G commercial hybrids of broiler chickens. The results of study indicated that the intermittent light programme 4L:2D or 3L:1D used in growing broiler chickens significantly affected the following traits in the examined strains of broilers: increased slaughter yield by circa 2.0%; higher yield of breast muscles by about 1.29%; of leg muscles by about 1.44% and lower amount of peritoneal fat tissue in the carcase by about 1.39%. The applied light system also improved the physicochemical characteristics of meat, i.e. pH15, pH24 and water holding capacity and decreased the intramuscular fat content. The kind of light programme affected the quality traits of carcase and meat both in Ross 308 and Hybro G strains of broiler chicken.
