Influence of grain-free foals diet on biochemical indicators of blood

Abstract

Purpose: to study the influence of the Bezernary diet on the parameters of growth and development of foalsfrom leaving to 1.5 years.Materials and methods. The object of the study was the young of the Oryol trotter. After leaning, two groups of 5 goals were formed in each. The concentrate part of the diet of the foals from the control group consisted of compound feeds based on micronized grain and balancing feed additive. The experimental group as concentrated food received granular beze -free compound feed and balancing feed additive. The beginning of the experience corresponded to the time of leaving the foals, when they reached the age of 6 months. Control points of accounting of growth and development indicators, as well as biochemical blood test - after 3 (I), 6 (II) and 9 (III) months after the start of the accounting period. Blood was taken from the jugular vein in front of the morning feeding. The concentration was determined: common protein, albumin, globulin, urea, alkaline phosphatase, amylase, glucose, cholesterol, calcium, phosphorus, magnesium, potassium, sodium, chlorides, iron, triglycerides, lipases. To control the growth parameters, they measured: the height at the withers, the slanting of the body, the gaping of the chest behind the shoulder blades, the girth of the heel, the width of the chest in the shoulder-lobe joints, the width in macloki. The indicators of absolute and relative growth in terms of measures for each accounting period were calculated.Results. According to the results of the 1st period, in the animals of the experimental group in comparison with the control, a reliable increase in the concentration of magnesium was revealed. At the end of the II period in the experimental group, the indicators of magnesium and albumins were significantly higher, and cholesterol and gamma-globulin are lower than in the control group at the end of the 3rd period in the control group the levels of cholesterol, iron and thyroxine were significantly higher. At the same time, in the experimental group, the concentration of cholesterol was lower than the boundary of the reference value for adult animals. In the same period, reliable differences were recorded by indicators of absolute and relative growth, which in animals of the control group turned out to be significantly higher. In the same group, the indicators of the measure of the oblique length of the body and the width of the chest in the shoulder-lobe joints were reliably lower.
