The Effects of Different Fat Sources on Bioproductive Performances and Essential Fatty Acids Composition in Broiler Breast

Since fats added in combined fodder may change the 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. Thus, an experiment was conducted over a period of 42 days, on four groups of broilers fed with a basal diet, which incorporated various fats (sunflower oil-2%, soybean oil-2%, linseed oil-2%, lard-2%). The bioproductive indicators (food intake, body weight gain, and the conversion index CI) were established during the experiment, and in the end, the content of essential fatty acids (linoleic and linolenic acids) in broiler breast were determined. The obtained data, analyzed and statistically interpreted, have revealed that the established (evaluated) bioproductive indicators in the four experimental groups did not differ significantly. However there are some variations in the fatty acids content in broiler chicken breast.There are, though, some variations of the determied fatty acids content in broiler breast, in pectoral muscles as well as in breast skin
