VARIABILITY AND ASSOCIATIVE RELATIONSHIP OF SOME BIOCHEMICAL INDICATORS OF BLOOD SERUM AND PHYSICAL-CHEMICAL PROPERTIES OF LARGE WHITE BREED STORES’ MUSCLE TISSUE

Abstract

The paper presents the results of studies of some biochemical parameters of blood serum and physicalchemical
properties of muscle tissue of Large White breed stores; the main biometric parameters that characterize
the variability of traits and their correlation were calculated. The experimental part of the research
was conducted in agricultural formations of Dnipropetrovsk region (“Agro-firm Dzerzhynets” LLC, and
“Agro-firm Vidrodzhennia” LLC), “Hlobyne meat-packing plant” LLC in Poltava region, the Research center
of biosafety and environmental control of agro-industrial resources of Dnipro State Agrarian and Economic
University, the Laboratory of zoo-chemical analysis of the Institute of Pig Breeding and Agro-
Industrial Complex of the NAAS, and the Laboratory of animal husbandry of the Institute of Grain Crops of
the NAAS of Ukraine. Control fattening of young pigs was carried out in agricultural formations according
to the generally accepted requirements (M. D. Berezovsky, I. V. Khatko, 2005). The content of total protein
(g/l), urea content (mmol/l), aspartateaminotransferase (AsAT) (mmol/h/l), alanineaminotransferase (AlAT),
(mmol/h/l), as well as alkaline phosphatase (units/l) (V. V. Vlizlo et al., 2012) were studied. In muscle tissue
samples, the following parameters were investigated: moisture retaining power (%), coloring intensity (units
of ext. × 1000), active acidity (pH) (units of acidity), tenderness (c), and losses during heat treatment (boiling
down) (%). Biometric processing of the obtained data was performed according to the methods of
G.F. Lakin (1990). It has been found that the blood serum biochemical parameters of the young pigs of
Large White breed correspond to the physiological standard of clinically healthy animals. The number of
high quality samples concerning moisture retaining power, %, coloring intensity, units. ext. × 1000,and tenderness,
c ranged from 12.0 to 16.0 %. Coefficient of variation of the blood serum biochemical parameters
and physical-chemical properties of the longest back muscle in animals of the experimental group ranged
from 2.49 (active acidity (pH), units of acidity) to 27.06 % (aspartateaminotransferase (AsAT) activity,
mmol/h/l). The reliable indicators of the correlation coefficient were established between the following pairs
of features: alanineaminotransferase (AlAT) activity × active acidity (pH) (r = + 0.443, tr = 2.37), alkaline
phosphatase activity × coloring intensity, units ext. (r = −0.483, tr = 2.65).
