We had a vet suggest feeding the positive wormer pelets with the Morantel tartrate in it every 3 to 4 weeks to try to help keep all the little worms down, while the system deals with the bigger prolems.
Nothing you mentioned treats tapeworms. Quest plus for horses(has the cydectin and praziquantel in it) or equimax(ivermectin and praziquantel) are two options for your herd. We use the equimax, 2 to 3 x the dosage for a horse.
Ivermectin plus given as an injectable 3 x every 10 days for possible liver flukes if you are more southern.
Synanthic is a white wormer and great all around wormer. I really felt that some of my kids having problems responded well to synanthic,.
I have not used the Baycox, We are using corid, and it seems to work well for us. Plus medicated feed with Rumensin in it.
This year we are using Corid(every 3 to 4 weeks in the drinking water) and Cydectin(3 x every 21 days), Plan on worming the entire herd here soon with Equimax to clean out any tapeworm problems. And for a couple younger animals that seemed to keep scouring on and off we gave them synanthic. My last doe that kidded was in May and her kid has for sure had a tougher time with the worm loads. Been a tough year.
