Protein metabolism, physicochemical properties and chemical composition of muscle tissue in Large White weaners

Abstract

We presented the blood serum biochemical parameters, physicochemical properties and chemical composition of muscle tissue in Large White weaners of British origin. We found that serum biochemical parameters in five months weaners were within the physiological norm (the content of total protein was 71.28 g/l (СV = 8.16%), creatinine concentration was 155.62 µmol L-1 (СV =14.13%). Studies of physicochemical properties and chemical composition of samples of Longissinus dorsi muscle of Large White young pigs show that the number of high quality samples in terms of moisture holding capacity, % is 12.0%, colour intensity, units of ext.×1000 – 16.0%, tenderness, s – 12.0% and fat content, % – 16.0%. We revealed significant correlations between moisture holding capacity and protein content (r = -0.484, tr = 2.65), moisture holding capacity and hygroscopic moisture content (r = 0.402, tr = 2.11). The correlation between total protein content in blood serum and fat content in muscle tissue was -0.257 (tr = 1.28), whereas the correlation between serum total protein content and calcium content in muscle tissue was 0.375 (tr = 1.94).
