Taking into consideration the role of selenium and vitamin E in metabolic processes of living organisms, the effect of these oxidants on slaughter value and carcass quality of commercial goose was investigated. The experiment was carried out on 200 one-day-old White Koluda geese that were randomly divided into two groups: 50 males and 50 females each. From first day until 13th wk of age the control group was maintained on commercial basic feeds, the experimental group received feed enriched with organic selenium (0.3 mg per kg) and vitamin E (100 mg per kg). Later on, for three wks all birds were feed with oat grain and cereals ground. At 112 day of live all birds were weighted individually and from each group 20 birds (10 males and 10 females) were chosen randomly, slaughtered and after 24 hours chilling at plus minus 4 degree C the following parameter were evaluated (in grams, exact to 0.1 g and % in relation to live body weight and eviscerated carcass with neck): eviscerated carcass with neck, neck without skin, wings with skin, breast and leg muscles, edible giblets (heart, liver, gizzard), skin with subcutaneous fat, abdomen fat and remainder of carcass. Feed supplementation with tested antioxidants had non-significant (P greater than or equal 0.05) effect on evaluated female traits, but significantly increased (P less than or equal to 0.05) the male live body weight and eviscerated carcass with neck. Irrespective of feeding group, significant sex differences were stated in majority of evaluated carcass elements.
