Kohnke's Own Cal-Xtra
Calcium Supplement for Horses Grazing on Oxalate Pastures
CAL-XTRA™ is recommended for race horses in training requiring a balanced calcium, phosphorus and magnesium supplement, with Vitamin A and Vitamin D to help ensure optimum uptake from the digestive system. The formulation is acidified to help assist calcium uptake from the small intestine, which is complemented by its Vitamin D content.
It is particularly recommended for stabled horses on diets low in sun-cured lucerne (alfalfa) hay, or with limited daily access to a sunny yard or turn-out area to synthesize vitamin D in their skin to meet their needs.
