6.14 Serum Vitamin B12 Concentrations in Growing Cattle and Their Relationship with Growth Rate and Cobalt Bullet Therapy
Published online by Cambridge University Press: 27 February 2018
Extract
The interpretation of serum vitamin B12 concentrations in cattle is not well established but a value <350 ng/1 is commonly used to describe adequacy (MAFF, 1978). Three separate experiments explore this interpretation and the ability of cobalt (Co) bullets to increase serum vitamin B12 concentrations in cattle. In all cases, vitamin B12 has been measured microbiologically, using the organism L. leichmannii. In experiment 3, a number of samples were additionally analyzed using a radio isotope dilution (RID) technique.
