title: [Inheritability of blood metabolite concentrations in cattle at different age periods and seasons of the year].
abstract: Coefficients of heritability of lipid, carbohydrate and protein-nitrous blood metabolites were studied through comparison of mothers and their daughters at different age periods (6, 9, 12, 15, 18 months and the 1st lactation) and seasons. The highest and most statistically significant are heritability coefficients of triglycerides, phospholipids, cholesterin, total lipids; coefficients of acetic acid, 3-hydroxybutyric acid, acetone and acetylacetic acid and blood glucose are lower. The highest coefficients of heritability among protein-nitrous metabolites are those of globulins; coefficients of albumins, total protein, blood amino nitrogen are lower. Heritability coefficients of blood metabolites, except albumins, globulins and glucose are stable enough at different age periods. No pronounced season differences are observed. The presence of high and statistically significant heritability coefficients of a number of blood metabolites, their age and season stability indicate the possibility of using these metabolites as additional tests in selection of dairy cattle.
