1. The presence of vitamin B12-forming strains of microbe was positively confirmed in the alimentary tract of ducks. Actinomycetes indicated strong B12-producing ability, but other microbes were rather weak in this ability.2. There was a fair quantity of vitamin B12 in the contents of digestive tract. Caecum was found to be maximum in gram per cent and small intestine to be highest in total quantity.3. Further feeding experiments with Co60Cl2 were repeatedly performed and the biosynthesis de novo of Co60-labeled vitamin B12 was positively confirmed in the digestive tract of ducks. Moreover, it was also found that the form of Co60 in the liver may be Co60-labeled vitamin B12.
