- 1. Riboflavin did not influence the incidence of dermatitis in turkey poults.
- 2. Biotin was found to be an anti-perosis and an antidermatitis factor.
- 3. The anti-perosis property of choline was confirmed.
- 4. Inositol did not influence the incidence of perosis.
- 5. One or more factors present in an eluate from an adsorbate of an aqueous extract of dried brewers' yeast possessed anti-perosis properties.
- 6. It appears, therefore, that at least three organic factors are required to protect the poult from perosis, namely, choline, biotin and an unrecognized factor or factors which can be adsorbed on fuller's earth or norite and subsequently eluted with ammonium hydroxide.
