Dietary lipid sources on the fatty acid profile of swine fat: a review
ABSTRACT: Swine production has focused its efforts to reduce the amount and improve the quality of fat deposited on carcass. Due to the association of the lipid profile with cardiovascular diseases, researches have been developed to understand how the deposition occurs and to improve the fatty acid profile of swine fat. Among the factors that affect the fat composition, race, sex, and diet, the third one has the greatest impact. Lipid inclusion seems to be a promising way to modulate the lipid profile of fat in pig carcass, with an effect on saturated, monounsaturated and polyunsaturated fatty acids. The effect is greater in that fatty acid with the highest concentration in the source used. Soybean oil can double the value of linoleic acid, a by-product of olive oil increases oleic acid by 4%, and flaxseed oil has the ability to increase α-linolenic acid from less than 1% to over 18% in total fatty acids. In addition to the source, the duration and concentration influence the modulation of the fatty acid profile.
