Dietary manipulation of meat fatty acid composition in Hungarian Mangalica and an industrial genotype pig
2006
Fat content and fatty acid composition were investigated in Musculus gluteus medius of pigs from two different breeds: traditional Hungarian Mangalica and a crossbreed of Hungarian Large White and Dutch Landrace. Animals of both varieties were divided into two groups and were kept individually on control or experimental mixtures of feeds. Experimental feed contained significantly higher amount of linoleic and linolenic acid than the control one. Significantly higher fat content was detected in meat of Mangalica pigs kept on both feed mixtures than in those of crossbred. The proportion of saturated fatty acids was nearly the same in the meat of both genotypes. More monounsaturated fatty acids were detected in Mangalica meat than in crossbred ones expressed in percent of total fatty acids and absolute amount, as well. As a result of experimental diet, percentage and absolute amount of oleic acid decreased significantly in both genotypes. Less polyunsaturated fatty acids expressed as percent of total acids w...
