Due to the considerable content of oleic, linoleic, linolenic and arachidonic acids goose fat is considered the safest animal fat. Geese raised on grassland (pastures) and fed diverse feeds consume more polyunsaturated fatty acids (PUFA) than poultry maintained under a closed rearing system, fed standard feeds, low in linolenic acid and PUFA and high in saturated fatty acids. In consequence, the meat and fat of broiler chickens and turkeys is lower in n-3 acids than geese meat and fat. Two strains of White Kołuda geese were examined: W11 and W33. In the chemical composition of breast muscles no significant differences were shown between strains except for the ash and cholesterol content, which were both higher in W11 geese of both sexes. Differences observed between the strains in breast muscle pH48, cutting force and coefficient of emulsion instability indicate that further selection of strain W33 for higher body weight may negatively affect the technological value of meat.
