Physical and biochemical profile of fox-gestational hybrids by sex and age

Purpose: The study of biochemical indicators of blood of females and males of fox hybrids with age.Materials and methods. Research was carried out on females and males of fox hybrids. The age dynamics of changes in the biochemical parameters of the blood was evaluated with a comparative analysis of 2 age groups: females and males of fox hybrids 2 and 5 months (n = 30). The animals were fed once a day (in the morning) with meat mixtures in accordance with age and physiological condition, contained under the same conditions. Blood from the animals was taken into a special test tube with an activator of a clot of lateral subcutaneous vein of the lower leg until morning feeding. They received serum from it by centrifugation at 2000 rpm for 15 minutes. To obtain information about the functional state of the body, biochemical tests were selected that reliably reflect the state of metabolic processes as carbohydrate, lipid protein: general protein, albumins, alanineaminotransferase, aspartaminotransferase, alkaline phosphatase, α-amylase, glucose, urea, creatinine.Results. Animals in the process of growth and development showed an increase in a number of indicators: urea, creatinine, total protein, albumin and glucose. ALT and AST activity, on the contrary, decreased with age, reaching minimum values 2 in 5-month-old animals. Alkaline phosphatase concentration also decreased with age. The level of α amylase during the growth and development of the animal did not undergo significant changes. Indicators of protein, carbohydrate metabolism, as well as renal markers and enzymes in fox-bearing hybrids are characterized by sex differences. Thus, the biochemical composition of the blood during the growth and development of the animal undergoes a number of changes. The collection and systematization of data will allow the calculation of the reference boundaries of the main blood parameters of lisopesse hybrids to assess the biochemical status of the beast by sex and age.
