To estimate how the lambs transition from a monogastric at birth to a grazing ruminant at weaning affects its dietary intake of trace nutrients from milk and pasture, and to determine whether its vitamin BWe reviewed published reports of field trials in New Zealand where flocks were managed on mixed sward pastures without additional supplements. Information on intakes of milk and pasture was drawn from studies of suckling lambs grazing with ewes for up to 20 weeks. We calculated the quantities of vitamin BEstimated Se intake increased from approximately 5g/day near birth to 25g/day near weaning, but Se absorbed was less variable, being approximately 10g/day. Estimated vitamin BFrom newborn to weaned, a lambs physiology develops from monogastric to ruminant. The change in diet from milk to pasture presents markedly different chemical forms and concentrations of some trace nutrients. Despite this, the vitamin B
