Fat acid composition of lipids in liver and oviduct of laying hens under different vitamin D3 content in ration

V. Yu. Gudyma, V. G. Janovich

The data on total fat acid composition of liver lipids of laying hens, which during the month were fed mixed fodder, containing vitamin D3 1250, 2500 and 3750 Io/kg are presented in this article. It was established, that increasing the level of vitamin D3 in the fodder at 50 % of the general norm increases the relative content of oleic and linoleic acids in liver lipids of laying hens. At the increase of level of vitamin D3 in the ration of laying hens to 3750 Io/kg total lipids in hens-layers is likely dose-dependent manner reduced the relative content of oleic acid and increases the relative content of linoleic, linolenic and arachidonic acids.
