Abstract
The article presents the results of studies of the physicochemical properties of the muscle tissue of young pigs of the large white breed, taking into account their intrabreed differentiation by some biochemical parameters of blood serum, and the correlation links between the signs are determined. The control fattening of young pigs of large white breed was carried out in the conditions of the farm according to the "Methodology for assessing boars and sows for the yield of offspring in the minds of breeding plants and breeding reproducers". In the blood serum of 5-month-old animals, the cholesterol content (mmol/l) and the concentration of total lipoproteins (mg%) were determined. The physicochemical properties of the longest back muscle (m. Longissimus dorsi) were studied taking into account the following indicators: "water-holding capacity, %", "active acidity 24 hours after slaughter (pH), acidity units", "color intensity, units extract х 1000", "tenderness, s "and" losses during heat treatment, %". Biometric processing of the obtained data was carried out according to generally accepted methods using the Data Analysis software module in Microsoft Excel. It was found that the biochemical parameters of blood serum (cholesterol content (mmol/l) and the concentration of total lipoproteins (mg %) in young pigs of the Large White breed correspond to the physiological norm of clinically healthy animals. The number of samples of the longissimus dorsi muscle (m. Longissimus dorsi) of the category "high quality "according to the indicators" tenderness, s "and" water-holding capacity, % "is 9.09 %, according to the" color intensity, units. х 1000" – 18.18 %. Reliable coef-ficients of pair correlation are established between the following pairs of signs: concentration of total lipoproteins х active acidity 24 hours after slaughter (pH) (+0.618), concentration of total lipoproteins х water-holding capacity (+0.712), cholesterol content х tenderness (+0.726), cholesterol content х losses during heat treatment (+0.784). Key words: muscle, tissue, young pigs, blood, biochemical parameters, serum.

Selection work in the pig breeding indus- search for effective biological markers for pretry provides for an increase in the reproductive dicting the physico-chemical properties and chequalities of sows and boars – producers, fat- mical composition of the muscle tissue of young tening and meat qualities of their offspring
Summary
It was found that the biochemical parameters of blood serum (cholesterol content (mmol/l) and the concentration of total lipoproteins (mg %) in young pigs of the Large White breed correspond to the physiological norm of clinically healthy animals. Longissimus dorsi) of the category "high quality "according to the indicators" tenderness, s "and" waterholding capacity, % "is 9.09 %, according to the" color intensity, units. An pigs of different breeds, types and lines remains important issue remains the problem of impro- relevant [1–8]. To solve this issue, a number of methods are sicochemical properties of the muscle tissue of used in zootechnics, namely: improving the qua- young pigs of the Large White breed, taking lity of feed, intensive use of breeding boars, into account their intrabreed differentiation by from which offspring with high water holding some biochemical parameters of blood serum capacity, color intensity, fat and protein content, and to determine the level of correlations betand more are obtained.
