METHOD OF PREPARING FEED FOR PIGS Russian patent published in 2001 - IPC

FIELD: feed production. SUBSTANCE: method involves successive reprocessing of basic raw material components in disperser, with soya beans, standard combined feed or grain mixture being used as basic raw material; filling disperser with water and soya beans in the ratio of 4:1 and providing first dispersion stage till soya suspension temperature reaches 90 C; providing second dispersion stage by dispersing produced soya suspension (soya milk) at soya suspension and standard combined feed ratio of 4:1. Upon first dispersion stage, the size of 50% of produced particles must not exceed 10 microns. Upon second dispersion stage, the size of 80% of produced particles must not exceed 10 microns, and temperature must not exceed 60 C. Upon termination of processing of basic material, produced mixture is infused for at least 4 hours. Produced feed is ready to be given to weaned pigs. Method allows negative effect during growing and development of this group of animals of critical factors, such as changing of feeding ration and kind of feed, to be substantially reduced. EFFECT: simplified method and increased liveweight gain. 7 cl, 2 tbl, 6 ex
