Vitamin B12 in the Blood and in the Liver of Normal and of Totally Gastrectomized Pigs

Abstract

Acta vet . scand. 1973, 14, 421-427. -The concentration of vitamin BI2 in the blood was studied in five totally gastrectomlzed pigs followed for 10-18 months, and in four controls followed for months. The concentration of vitamin BI2 in the liver was investigated in three pigs of each group. The content of vitamin BI2 in the blood was of the same magnitude in both groups. Thus, removal of the stomach does not compromise the normal presence of this vitamin in the blood. The BI2 content in the liver was also unaffected by the operation, whereas it was increased after simultaneous administration of vitamin Be. vitamin B 1 2 ; gastrectomy; pig; blood; liver.
