keep it out year round . Do you feed your children , your family the good nutrients , only part of the year ? Nope . Why. ? Because you want them to be as healthy as possible .
Common sense has to come in here somewhere .
if you want healthy animals you provide the most nutrients you can , including minerals , yearround , not part time . Why do cattlemen use mineral tubs ? Are they wasting all that money ?
More nutrients produces more healthy and bigger deer , including the antlers . Any mineral supplement will help your herd . If you just want to try and draw in the deer to a kill spot , most any salt will work including road salt . If you want to help your Herd health try Trophyrock , it has 65+ minerals in its natural form . The animals know the difference and will choose it first over the man-made stuff .
