BIOCHEMICAL COMPOSITION AND BIOLOGICAL ACTIVITY OF MARAL SKIN AND PRODUCTS OF ITS PROCESSING

Abstract

Results are given from a comparative analysis of the biochemical composition of raw stuffs and concentrates produced from skins of marals of different sex and age groups. The skins of maral stag, doe, calf and heifer calf in 3 pieces each were the material of research. The highest protein content of 92.8% was noted to be in the doe skin. The maximum fat content among the samples examined was observed in the heifer calf skin, and made up of 8.2%. The summer skin contained more moisture, protein and ashes by 10.3, 1.0 and 7.0% as compared to the winter skin. The concentrate from the doe skin exceeded those from skins of the other maral groups in the content of alanine, glycine, proline, isoleucine, methionine, phenylalanine, and also in the amino acid sum. The summer skin of maral stag considerably surpassed the winter one in the content of all amino acids, except for cystine: 1.66 times for dispensable amino acids, and 4 times for essential amino acids. The concentrate from the maral stag skin was superior in the macro elements sum; concentrate from the maral calf skin in the trace elements sum. The tonic effect of biosubstances was determined on experimental rabbits and mice. The maximum tonic effect was observed, when mice were fed on powders from the maral heifer calf skin. The hypotensive activity of pantocrine on the base of the maral skin averaged 20%. Biosubstances produced from the skin using the technology developed possess biological activity and tonic action that allows considering the maral skin as valuable raw material of antlered deer farming.
