Lack of production response in grazing dairy cows supplemented withlong-acting injectable vitamin B12

Abstract: Long-acting injectable vitamin B₁₂ used to treat and prevent vitamin B₁₂ deficiency is unlikely to improve the milk production of grazing cows when concentrations of vitamin B₁₂ in serum are >128 pmol/L.

“…Vitamin B 12 is synthesised by rumen microorganisms in the presence of cobalt in ruminants. Diet composition is also an important factor in the synthesis of Vitamin B 12 by microorganisms (Grace & Knowles, 2012 ). Vitamin B 12 also affects the function of enzymes affecting lipid metabolism, which may be why Vitamin B 12 deficiency may alter lipid metabolism.…”

“…[27][28][29][30] Secondly, the upscaling of meat production to satisfy increasing planetary demands has led to live-stock being husbanded under conditions wherein supplementation with either cobalt (to supply rumen microbes with the metal for B 12 biosynthesis) or with parenteral vitamin B 12 (to treat cobalt deficiency) are necessary for their own health and growth. [31][32][33][34] This requirement appears to be linked to unnatural feeding conditions typical of intensive animal agriculture, as free grazing animals do not have a need for supplementation with vitamin B 12 . 34 Thirdly, the high demand for meat on the planet does not permit the feeding of all humans with free-ranging grazing animals.…”

Since the transition toward plant-based diets that are devoid of B 12 is unavoidable, every effort should be made to prevent B 12 deficiency in vegetarians and vegans.…”
