Chemical composition and physical and chemical properties of muscle and fat tissue of pigs reared in the republic
Abstract
It was determined that young animals of Belarusian black-motley breed significantly surpassed on water-holding capacity samples of all imported species by 4.32-5.51 p.p., loss of meat juice were lower than in young animals of imported selection by 1,7-4.41 p.p. Analysis of chemical composition of muscle tissue showed that samples of meat of young animals of Belarusian black-motley breed had significantly more protein than samples of young animals of Landrace and Yorkshire meat breeds by 1.93 and 1.90 percentage points, respectively, and moisture content was lower by 2.66 p.p. Animals of Belarusian selection had higher intramuscular fat content level than animals of imported selection by 0.66-1.35 p.p. Chemical composition analysis of fat tissue showed that young Landrace and Yorkshire breed animals was inferior to animals of Belarusian selection for fat content, and also had a higher moisture content level.
