Lipid metabolism indices in the blood serum of reproductive female polar foxes in relation to age of animals
The study was carried out on 50 female polar foxes, which were divided into 5 experimental groups with respect to age (n – 10): from 1 to 5-years-of-age. The content of triglycerides, total cholesterol, HDL, LDL, total, free and estrified L-carnitine and the composition of fatty acids was determined in blood serum samples. The lowest content of triglycerides, total cholesterol and HDL fraction was found in one-year-old females (p < 0.05). It was observed that there was a tendency towards an increase in the content of triglycerides and LDL until 3-years-of-age and in total cholesterol and HDL until 4-years-of age. No significant, age-dependant changes in the content of individual fatty acids and L-carnitine were observed. Among fatty acids, the dominant ones were C16:0; C18:0; C16:1; C18:1 and n-6 PUFA, where C16:2 n-6 prevailed.
