THE DIFFERENCES IN THE CONTENT OF FATTY ACID IN THE MUSCLE AND FAT OF MANGALICA BREED INFLUENCED BY THE ADDITION OF flax and sunflower in the feed
The aim of the experiment was to determine the impact of flax and sunflower in the diet on the content of fatty acid in the meat and fat of mangalica breed. The experiment included 18 pigs of mangalica breed. The pigs were divided into the group of 8 pigs fed by the addition of flax and the group of 10 pigs fed by the addition of sunflower. The groups have equal sexes. The experiment was conducted from 30 to 100 kg live weight. Samples for the analysis of fatty acids were taken from the musculus longissimmus dorsi (MLD), musculus semimembranosus (MSM), musculus aductor (MA) and backfat and kidney fat. The selected groups of fatty acids were determined from the homogenate of muscle res. fat tissue using FT IR Nicolet 6700. The experimental groups were compared by the analysis of variance using SPSS-20. From the results we can conclude that in the group fed by the addition of flax, we found a higher content of polyunsaturated fatty acids in all the analyzed samples of muscle and fat, the saturated fatty acids were higher in the group fed sunflower diet. These differences were statistically no significant. Statistical significance at P<0.05 was confirmed only in the difference between the oleic acid in MLD, MA and stearic acid in the MSM. It was found no statistical difference in the content of fatty acids in fat of any of the monitored parameters.
