Zoohygienic justification of use of the extruded forage in feeding of calfs

Extruding of fodder composition improved its chemical composition which action amplified by a preliminary prorashchivaniye of one of its components that was confirmed in experiences on calfs, so the preliminary prorashchivaniye of grain of colza with the subsequent extruding (the third group) promoted larger increase in an average daily increase at decrease in expenses of a forage by 1 kg of an increase. Economic efficiency of extruding of fodder mix for 1 ruble of padding expenses made 4,27 rubles, and with a preliminary prorashchivaniye - 5,27 rubles.
