FATTY ACIDS PROFILE IN THE EGG YOLKS AND LIVER OF EMBRYOS AT DIFFERENT LEVELS OF CAROTENOIDS IN THE DIET OF CHICKENS
Journal Title: Acta Scientiarum Polonorum Zootechnica - Year 2017, Vol 16, Issue 2
Abstract
It is established that there is a certain correlation between the level of carotenoids in the ration of breeding hens during the reproductive period and the content of unsaturated fatty acids in lipids of egg yolks. The increased content of carotenoids in the diet of chickens during the reproductive period from 8 to 32 mg per kg of fodder contributed to the reduction of content of saturated fatty acids in egg yolks and increased of the content of unsaturated fatty acids in comparison with the control group. It was found increased content of polyunsaturated fatty acids: linoleic (C18:2w-6), docosapentaenoic (C22:5w-3), docosahexaenoic (C22:6w-3), eicosapentaenoic (C20:5w-3) and eicosatrienoic (C20:3w-9). The inverse relationship between the content of unsaturated fatty acids in the lipid composition of egg yolks and the intensity index of lipid metabolism in the liver of 19-day-embryos was observed.
