Vitamin A

Interpretation of Vitamin A Results in Cattle
Vitamin A deficiency can result in poor hair coat, slow growth and ocular conditions, and can occur when cattle are fed high concentrate diets, poor quality or old milk powder or when absorption is impeded. The reference range here pertains to older animals; in neonatal animals vitamin A levels depend mainly on colostrum intake and absorption, so insufficient colostrum intake or absorption will lead to lower levels of vitamins without there necessarily being a deficiency present in the dam. Vitamin A is heat labile, and exposure of the blood sample to bright sunlight for a short period of time can lead to its destruction and result in low levels being detected.
