METHOD OF PRODUCTION OF BIOLOGICAL PREPARATION FOR FEED PRODUCTION Russian patent published in 2015 - IPC A23K1/16 

FIELD: agriculture.

SUBSTANCE: method of production of biological preparation comprises the process of fermentation of the mixture of peat and organic wastes enriched with biologically active supplement, in three stages: first - for 48 hours at a temperature of 37°C, second - for 24 hours at a temperature ranging 55-60°C, the third stage - for 48 hours at a temperature of 37°C, followed by extraction of the solid phase fermentation product with 1% solution of potassium phosphate for 48 hours at a temperature of 22°C and the filtration of the extracted mass with obtaining liquid phase biological preparation. The organic waste is used as bird droppings, and the biologically active supplement - flour production wastes in an amount of 5% by weight of peat-dropping mixture. The initial mixture for fermentation is acidified with 50% acetic acid at a dose of 15 ml per 1 kg of peat-dropping mixture. The fermentation process is carried out under anaerobic conditions. The components of peat-dropping mixture are taken in the ratio 50:50. The filtration of the extracted mass is carried out at a pressure up to 3 atm.

EFFECT: obtaining low-cost and effective biological product that extends the range of biological preparations for silage of perennial grasses, the use of which provides enhancement of quality of silage feeds and improvement of the ecological situation of the environment.
