FIELD: feed industry.
SUBSTANCE: invention relates to a method for the production of coagulated blood meal and to a product of coagulated blood meal. A method for the production of coagulated blood meal is proposed, including subsequent stages of (i) provision of an aqueous mixture containing raw animal blood obtained from a slaughterhouse, and (ii) increase in a content of solid substances in the mixture to obtain a mixture having a content of solid substances of 20% by wt. or higher, and (iii) simultaneous drying and grinding of the resulting mixture in an air turbulent mill to obtain dried blood meal having an average particle size d50 from 20 mcm to 0.7 mm, d90 of less than 1 mm, according to the results of measurement with laser diffraction, using Beckman Coulter analyzer of a dry powder particle size, and intestinal digestibility of 85% or higher. Coagulated blood meal is proposed, obtained by the specified method, having an average particle size d50 from 20 mcm to 0.7 mm, d90 of less than 1 mm, according to the results of measurement with laser diffraction, using Beckman Coulter analyzer of a dry powder particle size, and having intestinal digestibility of 85% or higher and a moisture content of about 10% by wt. or less. The use of this coagulated blood meal as a protein dry filler and a taste booster of feed for pets or for aquacultures is also proposed.
EFFECT: invention is aimed at obtainment of high-quality blood meal with high intestinal digestibility.
