The requirement for vitamin K of some different species of animals

Abstract

The haemorrhagic disease in chicks reared on a diet inadequate in vitamin K has also been observed in ducklings and young geese, and in very mild degree in pigeons and canaries. Rats, guinea pigs and dogs kept for a long time on the ''basal diet showed no signs of the disease. Experiments with rabbits and pigs were inconclusive. The possible relation between K-avitaminosis and haemophilia in man is discussed.[long dash] Auth. summ.
