I use a Pneu-Dart pump up rifle from Livestock Concepts. I use it with Draxxin. Since I am by myself, if I do have one with a snotty nose, then I can get them dosed and on the way to recovery asap. Otherwise I have to drive them at least 1/4 mile to the chute and maybe then need some help to get them in the pens. With the price of cattle, and veterinary calls, 2 uses and you have paid for it. Draxxin is expensive, but that 14day treatment period is really a bonus. Those Safeguard wormer cubes are great also. I try to use them at least twice a year. When we get them in the chute I use the pour on ivermectin. A good worming program will prevent the need for the Draxxin also... Just my $0.02
