Kystsiv V. Lipid composition and lipid peroxidation process in quails tissues depending on different lipids and vitamin E level in the ration

Research purpose: to established optimal doses of sunflower oil and vitamin E additions into rations for Japanese quails with different composition of feed ingredients and theirs influence on total lipids content, lipid and fatty acid composition and lipid peroxidation intensity in tissues and also egg productivity and quality. Research object: lipid and vitamin exchange processes and lipid peroxidation intensity in tissues and egg yolks of obtained results. Scientific novelty of the obtained results: it was first investigated in complex influence of sunflower oil and vitamin E additions into rations for Japanese quails with different composition of feed ingredients on total lipid and theirs classes content, fatty acid composition, lipid peroxidation in tissues and vitamins A, E and carotenoids content in liver and egg yolk. It was established, that growing of metabolizable energy level from 287,7 to 314,7 ccal in standard ration and from 287,1 to 300,6 ccal in maize-fodder beans ration for Japanese quails by sunflower oil addition and increasing vitamin E level up to 40 g/ton of combined feed promote the increase of phospholipids and essential fatty acids level in tissues, decrease their lipid peroxidation processes intensity, improve laying performance, feeding and biological value of eggs by of increasing phospholipids, linolic and arachidonic fatty acids and vitamin E level. Organ-tissue characteristics of total lipids content, their classes, fatty acids composition and lipid peroxidation process in Japanese quails were investigated for the first time.
