Effect Of Feeding

The COMA report on The Nutritional Aspects of Cardiovascular Disease (1994) recommended that the intake of long chain n-3 polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), by the UK population should double. EPA and DHA in the human diet are derived principally from oily fish. The aim of this experiment was to determine the effect of increasing levels of fish oil in the diet at two levels of vitamin E supplementation, on intake, milk production, the extent of uptake of EPA and DHA into milk fat at levels exceeding those investigated to date, and the effect of a dietary supplement of vitamin E on fatty acid content.

Effect Of Feeding

The composition of fatty acids in food products is a significant factor in human health. Feeding can significantly influence the composition of fatty acids in the animal fat. We analysed the effect of feeding high CLA-content (conjugated linoleic acid) feed on the composition of fatty acids in pork. The animals were grouped according to the following: Group 1) feeding experimental, ghee-mixed feed for 76 days, Group 2) feeding the same feed, but only for 33 days, Group 3) feeding sunflower-oil-mixed feed for 76 days. Ghee contains CLA in high amount. The aim of our experiment is to analyse how the high CLA content influences the fatty acid content of pork. In the end of the fattening experiment the animals were slaughtered, then samples were taken from the loin, ham, abdomen and backfat from 10 animals from each group and analysed the fatty acid content. We found significant differences between the average fatty acid content of the samples. As an effect of feeding ghee-enriched feed, the CLA content significantly increased, compared to the control group. However, the linoleic acid and the arachidonic acid content were lower, and the proportion of fatty acids was also lower when feeding control feed.
