Tissues of 10 males of W31 White Koludzka breed were used as an experimental material. The geese came from two experimental groups, each of 30 males and 30 females, reared up to the 10th week of life. Breast, thigh and shank muscles of broiler geese fed with mixtures containing soybean extracted meal were characterized by slightly lower dry matter and crude protein contents, but larger crude fat comparison with geese fed with mixtures, in which soybean extracted meal was partly substituted by rapeseed extracted meal 00 (the differences not statistically proved). Similar fatty acid contents in breast muscles of tested geese were found. Moreover, during the raising no differentiation in the analysed acid profile in skin subcutaneous fat in relation to feeding were proved. On the other hand, thigh and shank muscles as well as abdominal fat in geese fed with mixtures containing soybean and rapeseed extracted meals were characterized by lower saturated fatty acid contents, and larger content of unsaturated fatty acids in comparison with birds fed with mixtures containing only soybean extracted meal (the differences not statistically proved)
