| Summary: | The results of morphological and biochemical analysis of Hereford cows imported in 2012 from Australia to the Amur Oblast are presented in the paper. Blood parameter assessment of heifers obtained from the abovementioned cows, cross mated with local Hereford bulls, is given here. All animals were managed under identical conditions: on natural pastures in summer and at stables during cold seasons. Deterioration in some types of metabolic processes was noted in mother cows, in particular based on sera test results, the decrease in albumen synthesis resulting from the increase in blood urea nitrogen in protein metabolism, reduction of glucose content in carbohydrate metabolism, low contents of calcium and magnesium in the mineral metabolism. Fat metabolism parameters (lipid, cholesterol and triglyceride contents) were within the normal range. Biochemical parameters of heifer sera as compared to mother cows were closer to the normal range; i. e. albumen concentration and glucose content were higher, BUN level was lower, calcium and magnesium contents were identical to adult animals' ones. It was established that during winter time and after it young animals are more demanding to feeding and management conditions. |
