Abstract
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 kg-1) and vitamin E (100 mg kg-1).
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 +4°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≥0.05) effect on evaluated female traits, but
significantly increased (P≤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.
