Features of vitamin E antioxidant effect on oxidative damage of geese meat
Journal Title: Біологія тварин - Year 2017, Vol 19, Issue 3
Abstract
Features of influence of doubled dose of vitamin E in the diet of geese during pre-slaughter period on the quality of geese meat and its oxidative damage during its low-temperature storage were established. During the entire period of postnatal development, the geese in the control group were kept on a standard diet, balanced on exchange energy, protein and vitamins. The diet of the geese in the experimental group from 42 to 63 days differed by doubled up vitamin E content (40 mg/kg). Bird slaughter was carried out at 63-day old age. After the slaughter from the carcasses, the meat of the breast was cut out and frozen in a slow way to a temperature –18 °C. For the low-temperature storage, geese meat of two samples was used. The meat of the control sample was obtained from the geese of the control group, and the meat of the experimental sample was from the geese of the experimental group. The intensity of lipid peroxidation processes in geese meat was evaluated by the content of peroxidation products which react with 2-thiobarbituric acid (TBАAP). The determination of these products was carried out in meat homogenates (TBAAPin) and on the initiation of peroxide oxidation of Fe2+ (TBAAPinit). In addition, the content of vitamins A, E and β-carotene was determined in geese meat. It has been established that the introduction of vitamin E in the diet of geese in a dose of 40 mg/kg of feed during this period contributes to reliable inhibition of lipoperoxidation processes in their meat during low-temperature storage. The meat of these geese is characterized by a significantly higher content of vitamin E throughout the experiment and by 29.1 % higher content in β-carotene at the end of the experiment. Thus, the doubled dose of vitamin E before slaughter not only improves the quality of paired meat, but also inhibits its oxidative damage.
