nutrients

Hey all, Wondering what you all do to make sure your deer are getting their required amount of macro and micro-nutrients? Reading on the subject ive learned that they need calcium, phosphorous, magnesium, potassium, sodium, sulfur, selenium, cobalt, copper, zinc, iodine, iron, manganese...

I know one of the main factors in antler size is genetics but what nutrients ,vitamins give the best protential for a good set? Thankyou all
