MANUFACTURING PROCESS FOR MAKING ANIMAL FEEDS

摘要

An animal feed additive contg. Bacillus licheniformis MN-001 cultures is prepd.. Thus, a preculture of B. licheniformis MN001 is inoculated into a culture medium (pH8.0) contg. 2 molasse, 1 (NH4)2SO4, 0.1 K2HPO4, 0.05 yeast ext. and 100 parts tap water and cultivated on a shaker-flask at 20-50≦̸C for 12-120 hr. The fermentate is centrifuged and the collected cell is mixed with starch (or defatted rice bran) to provide the MN-001 prepns.. The strain extracellularly forms protease and cellulase in high yields. The feeds are harmless to animals, but they improve the survival wt. of young pigs, the growth rate of young cattle, they cause a general increase in animal body it.
