DEPENDENCE OF THE BLOOD BIOCHEMICAL INDICES SILVER-BLACK FOXES ON THE SEASON IN THE NORTH OF TYUMEN
With the use of laboratory methods for the analysis of blood biochemical parameters fur-bearing animals. Shows the changes in the blood of silver-black foxes depending on the season, age and sex under the influence of environmental factors in the north of the Tyumen region. We study the main types of metabolism: protein, carbohydrate, fat, and enzyme activity. It is established that the rate of total protein silver-black foxes to 4 months of age reached the reference range, regardless of gender, the level of carbohydrates in the winter time in the young is 15 % higher than in adults, in young foxes lipid levels in the winter above; liver enzymes adult silver foxes above 20 %, compared to young animals, the number of alkaline phosphatase and 2.5 years for fur-bearing animals regardless of sex remains high.
