The statistics provide data on the fractional composition of blood plasma proteins that are determined by electrophoresis in a polyacrylamide gel. For the study, selected high-yielding lactation cows I, II, III and VI lactation for 10 lobes of each lactation. Selection of animals in the groups was carried out taking into account body weight, daily milk supply, and for cows II, III and VI lactation - the productivity of the past lactation.
In accordance with the average daily allowance for milk of cows I lactation was divided into two groups: the first - with an indicator of the supply of 20-25 kg, and the second - 30-35 kg of milk per day. In the same way, they were divided into groups of cows II and III lactation. The fourth group included cows IV lactation with milk yield of 30-35 kg of milk per day.
After morning milking in cows of all groups studied clinical parameters. There were no differences between the experimental groups of cows and such parameters as the level of ceruloplasmin, haptoglobin, plasminogen, transferrin, albumin and pre-albumin in the blood plasma of cows. All these protein fractions of blood plasma of cows were at the level of similar indices obtained in other periods of research on the same animals. The obtained data testify to the high intensity of biosynthesis of protein in tissues of high-yielding animals.
