title: [Total protein, protein fraction and free amino acid changes in the blood serum of chicks and pigs raised with supplementary amounts of amino acids].
abstract: The effectof various quantities of lysine and methionine in bird and pig rations on the dynamics of total protein, protein fraction and free amino acids in the blood serum was studied. Total protein in the blood serum is reduced by about 30% in chickens and by 40-50% in pigs suffering from lysine toxicosis and 20-25% in chickens, and 45-50% in pigs suffering from methionine toxicosis. A proportional correlation between lysine quantity in the ration and albumen level in the blood serum was observed. In case of methionine toxicosis the quantity of albumens and alpha-globulins is reduced, while that of gamma-globulins is enhanced. Free amino acid level in the blood serum is directly correlated with the quantity of amino acids in the ration.
