The natural manganese soil was collected from Kangwon province. Manganese soil mixed with milk acid pathogene solution was made by laying it on freely after mixing as a rate of manganese soil 1 to milk acid pathogene solution 5. The biological value of its mixed solution in the manganese metabolism level or fattening tests was 51.15-54.88 percent. The productive effect of the mixed solution was high even when feeding nearly half amount of it as compared with natural manganese soil
