Nelson, C. et al.  Vitamin D status of dairy cattle: Outcomes of current practices in the dairy industry. Journal of Dairy Science. December 2016, Volume 99 :12: 10150–10160. DOI: https://dx.doi.org/10.3168/jds.2016-117

“The need for vitamin D supplementation of dairy cattle has been known for the better part of the last century and is well appreciated by dairy producers and nutritionists. Whether current recommendations and practices for supplemental vitamin D are meeting the needs of dairy cattle, however, is not well known. The vitamin D status of animals is reliably indicated by the concentration of the 25-hydroxyvitamin D [25(OH)D] metabolite in serum or plasma, with a concentration of 30 ng/mL proposed as a lower threshold for sufficiency. The objective of this study was to determine the typical serum 25(OH)D concentrations of dairy cattle across various dairy operations….” Read More
