Hypercalcemia and hypervitaminosis D in two lambs.
Twin 17-day-old crossbred male lambs were examined to determine the cause of weakness and failure to thrive. Hypercalcemia attributable to hypervitaminosis D was diagnosed. The milk replacer or an accidental overdose of an injectable vitamin D product was suspected to be the source, although a definite cause was not confirmed. Lambs responded favorably to palliative treatment (administration of saline [0.9% NaCl] solution to induce calcium diuresis) and changing the diet to another milk replacer.
