The Effect of Chosen Food Oils to Supplementation of Last Fattening Pigs Period on Fatty Acids Structure in Pig Muscle Fat and the Consumption Preference

Abstract

Fatty acids profile in broilers feed, it is possible to influence their share in a desired structure, which can balance the n-6:n-3 ratio in food, according to the consumers needs. Flax seed to lactating goats can be used as nutritional supplement to reduce saturated fatty acids and increase polyunsaturated fatty acids in milk. A significant increase in CLA in milk was achieved by supplementation to goats. In experiment last month of fattening group of pig in five groups of pig was fed with a basal diet, which incorporated various fats (canabis oil-2%, soybean oil-5%, linseed oil-5%, raps oil5%). The indicators (food intake, body weight gain, and the conversion) were established during the experiment, and in the end, the content of essential fatty acids (linoleic and linolenic acids) in pigs meat were determined. The data was analyzed and statistically interpreted. By the four experimental groups, there are some variations of the determined fatty acids content in pectoral muscles as well as in breast skin.
