Lipid spectrum of blood when vegetable fats are introduced into the diet of calves

Abstract The study of metabolic effects of lipophilic vegetable products: sunflower (I group, n=3), palm (II group, n=3) and linseed oil (III group, n=3) were carried out on calves at the age of 9 months (n=3) with a body weight of 215–220 kg. The introduction of sunflower and palm oil was expressed by the increase in high density lipoproteins H S -HDL and OHs. According to H S -HDL/H S -LDL accumulation ratio, the test fats were arranged in the groups as follows: II (1.82)>III (1.78)>I (1.74)>control (0.77) conv. units. The effect of vegetable fats on the blood serum of experimental animals according to OHs/Hs-HDL index was as follows: III (0.34)<I (0.36)<I (0.38)<control (0.46). Thus, the introduction of oils reduces LDL and the atherogenic index in blood serum with a significant increase in HDL. This can serve the basis for the use of vegetable oils as promising natural hepatoprotectors in feeding animals, and at the stage of growing it will help to monitor the level of lipids in the body of calves and to calculate them in diet formulation.
