CHANGES IN AMINO ACID COMPOSITION OF BLOOD PROTEIN HYDROLYSATE DEPENDING ON THE RAW MATERIAL PREPARATION MATERIAL

Abstract

The raw material for blood protein hydrolysate preparation is whole animal blood, its clots and other serum production wastes. The dependence of amino acid composition of blood protein hydrolysate on the season of the raw material preparation was studied. The research lasted three years. It was demonstrated that the amino acid composition changed depending on the season. The peak, as a rule, was during summer months when their amount increased by 1.2–2.3 times and during autumn and winter it went down by 1.2–1.4 times (the difference is considerable, р < 0,05). The peak of glutamic and asparagine acid growth was in November when their amount was 1.4 times higher then during the previous months (р < 0,01). The increase of alanine, asparagine, valine, lysine, methionine, histidine, proline, tyrosine, threonine, and phenylalanine by 1.3–1.8 times was observed in March (the difference is considerable, р < 0,05). The amount of histidine, glycine, leucine, serine, and tryptophane in the beginning of spring was at the same level and the amount of arginine, asparagine, isoleucine in March decreased by 1.2–1.6 times (the difference is considerable, р < 0,01). So, it was determined that the dynamics of BPH amino acid composition was directly associated with the seasonal dynamics of physiological and biochemical cattle blood values. It was noted that in case of considerable change in absolute amino acid parameters their relative amount, in general, remained constant.
