METHOD FOR OBTAINING BIOLOGICALLY ACTIVE PREPARATION OUT OF COLOSTRAL WHEY Russian patent published in 2005 - IPC

FIELD: veterinary science.

SUBSTANCE: one should collect summer colostrums in cows to be filtered, poured into sterile tanks per 1-1.5 l and frozen in freezing chambers at -20 - -22 C. In winter-spring period colostrums should be gradually defrosted while calves are being calved. To remove casein in raw material one should apply abomasal enzyme - pepsin (4-6 g pepsin/l colostrum). This enzyme should be added into colostrums heated up to 38 C. After casein precipitation on should filter the whey to be conserved with potassium sorbate (1 g potassium sorbate/l whey). The method is very simple and enables to obtain high-quality preparation.

EFFECT: higher efficiency.
