dc.abstract.enThe aim of the study was to analyze some slaughter traits in 3 breeds of geese: the commercial hybrids of White Kołuda (W-31), and birds of conservative flocks of Pomeranian (Po) and Kielecka (Ki) geese depending on sex and length of rearing period, and to determine the relationships between the analyzed traits and factors. A total of 19 traits divided into 2 groups—measured and calculated traits—were statistically analyzed. The measured traits (g) included 11 parameters: preslaughter weight, carcass weight, weights of breast muscle, thigh and drumstick, abdominal fat, skin with subcutanenous fat, neck without skin, skeleton with dorsal muscles, wings with skin, total muscles as the sum of all breast and leg muscles, and the trait broth elements as the total weight of neck, skin, skeleton and wings. The calculated traits included 8 parameters (%): dressing percentage—carcass weight to preslaughter weight, meatiness—total breast and leg muscle weight to carcass weight, abdominal fat weight to carcass weight, weight of skin with subcutaneous fat to carcass weight, weight of neck without skin to carcass weight, weight of skeleton with dorsal muscles to carcass weight, weight of wings with skin to carcass weight, as well as total weight of neck, skin, skeleton, and wings. The presented results concerning the analysis of selected slaughter traits of the Kielecka, Pomeranian and White Kołuda geese indicate that these birds exhibit good slaughter value (dressing percentage from 60.80 to 66.50%). The selected values of this parameter were influenced mainly by genotype and to a lesser extent by sex. The White Kołuda geese were characterized by significantly higher values of the majority of the analyzed slaughter traits, both measured and calculated ones. In turn, the lighter domestic geese of regional breeds were characterized by significantly higher carcass meat content (from 31.69 to 35.13 % vs. from 29.28 to 31.80 %) and lower carcass fatness (abdominal fat and skin with subcutaneous fat from 21.26 to 25.45 % vs. from 30.81 to 33.14 %). This points to the possibility of using these breeds of geese in breeding work aimed to produce a hybrid characterized by medium body weight (intermediate between these values for the White Kołuda geese and Kielecka or Pomeranian geese), good dressing percentage as well as high carcass meat content and low carcass fatness.
