Components of physicochemical properties and chemical composition of mus-cle tissue of young pigs of different growth intensities, the level of their pheno-typic consolidation, and correlation

The work presents the results of study some biochemical indicators blood serum, physicochemical properties, and chemical composition muscle tissue young pigs large white breed calculation correlations between main quantitative characteristics. was carried out in agricultural formations Dnipropetrovsk region, research center for biosafety environmental control resources Dnipro State Agrarian Economic University, LLC “Globynskyi Myasokbinat” Poltava zootechnical analysis laboratory Institute Pig Breeding Agro-industrial Production National Academy Sciences animal husbandry state institution “Institute Grain Crops NAAS”. Studies fattening meat qualities show that animals controlled population belong to elite class by age reaching a live weight 100 kg. This indicator experimental group ranges from 167 188 days. It established number samples longest back high quality according “moisture retention capacity” is 12.0 %, “fat content” – 16.0%, “tenderness” 12% “color intensity” 16%. A level phenotypic consolidation II (the kg 177–188 days) content total moisture (K1 = +0.458, K2 +0.456), air-dry matter +0.492, +0.500), ash +0.527, +0.534), fat +0.559, +0.518) calcium +0.385, +0.415). Reliable were following pairs traits: moisture-holding capacity × protein (r -0.484, tr 2.65), at which reached (Ca) -0.392, 2,15), +0.447, 2.40), loss during heat treatment -0.390, 2.14). indicates effectiveness using “age weight, days” early prediction (Ca), capacity, breed.
