You can do the same with Valbazen, pour on feed, let dry and trough feed it. BUT - do not give Valbazen to bred doe. Fawns, bucks, does nursing babies all fine, but NOT bred. The possibility of birth defects has not been ruled out in pregnant animals.
The Safeguard pellet is an alfalfa pellet, coated in wormer, so they eat it pretty well.
Or, you can use the MaxRax or other brand feed that offer a wormer mix.
There are also some types that can be put in the water supply, but I have not used any so can't make a specific recommendation.
Be sure to rotate products, so that you don't allow your herd to develop a super-worm that becomes resistant to one particular wormer.
