Around here Cattle Grubs and worms are the problem are the same problem as elsewhere. I haven't seen a deer with Grubs but doesn't mean they are not a problem for them. Neighbor has feeder cattle and deer sometimes feed on his property. I have read of feeding medicated goat feed to deer in spring to rid the deer of any intestinal worms. Not sure that address Deer herd heath adequately, but I'm not up to chasing them down and tacking them to Vet, especially perhaps two hundred. What kind of feed and supplements and amounts do you Folks use to keep your deer herd healthy? On edit there is supposed to be an in Supplemental, in the title.
