BSK;

Cattle and deer basically have the same digestive system. I can't find a chart that says how much salt and minerals improve antler growth. What I have found is from livestock books. They speak of calcium, phosphorus, salt, iodine and cobalt being deficient in some soils and crops. So it may be a case of the deer living up to genetic potential by not being deprived rather than an increase based on the amount fed. They say that a lack of these chemicals will result in: poor bone growth, poor fertility, goiter, unthriftiness, listless, rough coats, anemia and weight loss. If they are lacking in these elements they develop a depraved appetite and eat wood, soil etc. It appears to be recommended that salt/mineral blocks should provided free choice for all grass eating animals.
