“…More significant differences in the tissues of 49-day old geese of the control and experimental groups were determined for PUFA in the cardiac muscles (increases in the contents of linoleic and linolenic acids and decreases in the levels of arachidonic and docosahexaenoic acids). It has to be noted that according to the results published earlier, a similar effect of the extract was seen in the liver tissues as well (Danchenko et al, 2020).…”

Among natural antioxidants, increasing attention is being drawn to avenanthramides - phenolic compounds of the common oat Avena sativa (Linnaeus, 1753). Research has shown that avenanthramides have much higher antioxidant activity than well-known bioflavanoids. Currently, a great deal of work is being conducted on the structure of these compounds and mechanisms of their effect on the organism of humans and animals. We explored the specifics of the influence of aqueous extract from A. satíva on the antioxidant activity and fatty acid composition of lipids of histologically similar tissues of geese with different levels of aerobicity (muscles of the stomach and cardiac muscle), dynamics of the birds’ live weight and pterylographic parameters under physiological loading by the development of contour and juvenile feathers. The addition of extract of oat to the diet of geese during growth of feathers was observed to increase the antioxidant activity of their tissues. Physiological loading related to the development of contour feathers in the examined tissues of geese significantly weakens as a result of selective inhibition of synthesis of unsaturated fatty acids, especially oleic acid, the content of which in 28-day old geese of the experimental group decreased by 31.7 in the cardiac muscle and 46.8 times in the stomach, compared with the control. Further changes in fatty acid composition were characterized by lower number of differences between the control and experimental groups. Increase in antioxidant activity in these tissues during development of juvenile feathers (day 49) occurs as a result of activation of alternative mechanisms of antioxidative protection, which take place with no significant changes in fatty acid composition. Furthermore, we determined that in the stomach and cardiac muscles of geese, the action of extract from common oat activated mechanisms of antioxidative protection, which increased the level of correlation between the changes in fatty acid composition. The study confirmed that the extract caused not only significant increase in the weight of geese at the end of the experiment, but also improved their pterylographic parameters. Therefore, it is practical to conduct similar studies on wild species of birds grown for hunting, because this process of development of feathers, particularly for such species of birds, is essential.

“…Research by Danchenko et al (2020) revealed specifics of changes in fatty acid composition in the tissues of the brain, liver and skeletal muscles of geese consuming extract of common oat. The research found abnormal fluctuations in fatty acid composition of lipids in these tissues during physiological loading with feather development.…”

“…Дослідження змін жирнокислотного складу (ЖКС) ліпідів тканин гусей під час формування контурного і ювенального пір'я дозволило визначити рівень впливу цього механізму на підвищення адаптивних потенцій гусей в зазначеному періоді їхнього розвитку. Результати досліджень ЖКС тканин гусей в цьому досліді було оприлюднено раніше [8]. Доведено, що саме під час формування контурного пір'я в 28-добових гусенят підвищення антиоксидантної активності тканин, і в тому числі й печінки, під впливом екстракту відбувалось на тлі різкого падіння як сумарного вмісту НЖК, так ненасиченості ЖК ліпідів.…”

The use of antioxidants in poultry feeding helps to relieve stress of various etiologies. Natural antioxidants have a number of advantages over synthetic ones. The aim of the study was to determine the effect of Avena sativa oat extract on the peculiarities of the functioning of the antioxidant system of goose liver during the physiological stress of contour and juvenile feather formation (from the 14th to the 56th day). The state of the antioxidant system in liver tissues was determined by the coefficient of antioxidant activity, the content of the final products of lipoperoxidation, the activity of antioxidant enzymes and the content of fat-soluble vitamins. The results of the experiment showed that the goslings of the control group during the formation of contour feathers have a decrease in antioxidant activity of the liver by 2.36 times, and juvenile — 1.90 times compared to the initial value of this indicator. Adding oat extract to the diet of geese during feather formation increases the antioxidant activity of their liver. Under the influence of the extract, the physiological stress associated with the formation of contour feathers (28 days) is significantly reduced by reducing the content of the main substrate of lipoperoxidation of unsaturated fatty acids, despite the decrease in the activity of all antioxidant enzymes. Increasing antioxidant activity in the liver during the formation of juvenile feathers is due to the inclusion of alternative mechanisms of antioxidant protection, implemented by increasing the activity of endogenous antioxidants: superoxide dismutase by 29.6 (P≤0.05), catalase by 34.6% (P≤0.05), glutathioperoxidase by 41.2% (P≤0.01), and the content of vitamin E by 32.7% (P≤0.05) and β-carotene by 30.9% (P≤0,05). Under the influence of the extract there is not only a significant increase in the weight of geese at the end of the experiment, but also an improvement in their pterylographic performance. Therefore, in the future, it would be advisable to conduct similar studies on wild bird species in kennels, as the process of feather formation is of fundamental importance for these birds.
