The level of polyunsaturated fatty acid-linoleic and cholesterol was evaluated in broiler chickens' muscle tissue and laying hens' egg yolk in the trial conditions depending on linoleic acid content in fed out feed that was provided by different additives of soybean and rape seed oil. It was ascertained that linoleic acid content in broilers chickens muscle tissue was 0.036-0.059% and in egg yolk 0.79-1.94% from total lipides' amount. Total cholesterol level in broilers muscle tissue - 46.00-66.50% and in egg yolk 0.45-0.52%. Linoleic acid content in broilers muscle tissue and in egg yolk was influenced by it's amount in feed ration. Linoleic acid level in muscle tissue increased by 0.005-0.023% if linoleic acid content in broilers' feed was increased by 0.22-0.46%. Linoleic acid amount increasing in layers feed by 0.43-1.38% caused increased linoleic content in egg yolk by 0.41-1.15%. Increasing of linoleic acid content in muscle tissue and egg yolk was observed simultaneously with the total cholesterol content decreasing in the products.
