Which showpig wormer do you guys use? Should I rotate the wormers or just use the same one as before?

We alternate ours for the showpigs. They get the intial ivomec at 4 months, then we alternate between safeguard and atgard.

We also rotate between Ivomec and atgard. Seems to work well.

I rotate Ivomec and Safeguard.

We use Banminth when we put them on dirt for the first 40-60 days and then use one more treatment of safeguard a little later in the feeding period. The only time we use an ivermectin product is when we see some mange or to treat pigs we buy when they are isolated.
