Taking into consideration that the energy source added to the combined fodder can significantly modify the fatty acids profile in broiler food, through its redirection even the fatty acids profile of carcasses can be modified through enrichment in a certain fatty acid and obtaining functional foods. An experiment was coduced on broilers, made up of three experimental groups, fed with a combined base fodder in which 2% of different fat sources have been incorporated (sunflower oil, soybean oil, linseed oil). The experimental period was of 42 days, during which the bioproductive indicators have been established (food ingestion, weight gain, conversion indicator), % of fatty acids in 100 g product (linoleic acid, linolenic acid and oleic acid), ∑SFA, ∑MUFA, ∑PUFA and the ratio between linoleic acid and linolenic acid, in thighs (Th), thigh skin (ThS) and abdominal fat (AF) in the broilers from the experimental groups. Fatty acids were determined using gaz cromatography.
The data obtained after statistc processing and interpretation have highlighted the fact that, concerning the bioproductive indicators, the three experimental groups do not differ. Regarding the fatty acids profile in thighs and abdominal fat there are some variations in the determined fatty acids content, which denotes that they can be influenced by food factors.
