Evaluation of fatty acid composition of forage grasses of winter-grazing pastures in Central and Northeast Yakutia. M.N. PAK, R.V. IVANOV, U.V. HOMPODOEVA (Yakut Scientific Research Institute of Agriculture named after M.G. Safronov, Yakutsk).
The article presents the results of the study of nutrients and fatty acid composition of seeded and natural grasslands,
horsetail and horsetail-free pastures in Yakutia. It was found that unsaturated fatty acids dominate in the composition of oat lipids, the total content of which was 56.59 %, while the natural grass stand oats have almost 2 times less (31.15 %). Variegated horsetail contains a significant amount of polyunsaturated fatty acids, especially linoleic and arachidonic. Horsetail pasture is superior to mixed grass pasture in terms of protein, fat, ash and nitrogen-free extractive fraction, except fiber. The results that we obtained indicate the need for widespread use of oat crops and horsetail pastures in breeding herd horses of the Yakut breed.
