IMMUNE AND THIOL-DISULFIDE STATUS IN PIGS KEEPING ON LOW-PROTEIN RATIONS WITH VARIOUS METABOLIC ENERGY AND AMINO ACIDS
M.A. Voitekha, A.A. Gagloshvili
In crossbreed piglets, keeping at low-protein rations with addition of limiting amino acids (lysine, methionine, threonine) to the standard (I group, control), or by 22-23 % (II group) and by 40-52 % (III group) above the standard (in connection with growing period), at the increase of amount of metabolic energy by 5.0 and 10.0 %, respectively, at the cost of vegetable oil addition, the authors determined the concentration of malonic dialdehyde, SH-/SS- exchange and content of M and G immunoglobulins in blood plasma and serum. The ration causes no significant alteration in content of immunoglobulins M and G classes, but affects thiol-disulfide exchange in animals. The increased nonspecific resistance, revealed in the pigs of II group, promote to enhancement of productivity.
Key words: pigs, raw protein, amino acids, sulfhydryl groups, immunoglobulin, malonic dialdehyde, nonspecific resistance.
