Absence of a weight gain response to Vitamin B12 supplementation in weaned dairy heifers grazing pastures of marginal cobalt content

extract

Unfortunately there is an error in the paper by Clark et al. in the August 1999 issue of the Journal (Vol 47, 125-127, 1999) entitled: “Absence of a weight-gain response to Vitamin B₁₂ supplementation in weaned dairy heifers grazing pasture of marginal cobalt content”. In the Materials and Methods section, the dose of hydroxycobalamin administered to the treated group reads “2000 mg”; the correct dose is “2000 𝛍g”.
