The effect of diet and sex on lipids composition of dried pork neck

The aim of the study was to investigate the effect of diet and sex on fat content, fatty acid composition and cholesterol content of dried pork neck. There were 12 barrows and 12 gilts separated in 4 groups regarding different nutritive supplement. The first group was fed basic ratio with supplement of linseed, the second with canola, the third with canola and vitamin E and the forth group without nutritive supplement (control group). All 24 samples of dried neck were analyzed in laboratory. There was no effect of nutritive supplement on fat and cholesterol content. Diet with linseed resulted in higher α-linolenic fatty acid content in dried neck. Canola diet resulted in higher oleic and linoleic acid contents. Barrows dried necks were fattier than gilts, but there were no difference in cholesterol content. Gilts had more polyunsaturated fatty acids and less saturated fatty acids than barrows.
