Maintenance nutrition in the adult pigeon, and its relation to torulin (vitamin B1). I

Abstract

In adult pigeons feeding naturally upon whole wheat or polished rice, there was a rising, falling or maintenance nutrition as well as a minimum, intermediate or maximum weight. These conditions occurred with or without supplements of marmite or torulin concentrates. Vitamin B1 from yeast did not give maintenance nutrition in pigeons unless supplemented with some other factor.
