In this study, a whole transcriptome analysis of breast muscles was conducted in broiler chicken groups differing in shear force. Shear force is a determinant of tenderness, which in turn is one of the most important parameters of meat quality in chickens. In our analysis, a total of 11 560 transcripts and 9824 genes per sample were identified. In chickens with more tender meat, up‐regulation of 19...
The calpain family includes proteolytic enzymes, which have a high capacity to degrade cytoskeletal and muscle fibre proteins. Thus they play an important role in the fusion of myoblasts and in cell proliferation and growth. The CAPN1 gene has been selected as a ‘candidate gene’ for meat quality in many domestic animals, including chickens. Consequently, the aim of our study was to identify new polymorphisms...
The aim of the study was to determine the effect of slaughter age of broiler chickens on macromineral levels of breast and leg muscles and their association with meat quality. Used were fast-growing Hybro chickens kept on litter and fed the uniform diet. Ten chickens weighing 2 kg each were selected for slaughter at 35, 38 and 42 day of life. Breast and leg muscles were evaluated for pH,colour (CIELAB),...
The aim of the study was to determine the effect of free-range raising system on production results and carcass and meat quality of broiler chickens aged 42 days, using fast growing Ross 308 line. Day-old chicks were randomly assigned to two groups, 120 birds in each. Group I throughout rearing remained indoors on deep litter while Group II was kept at free range. Production results,carcass quality,...
