HotelParasite
The combined meds are much more expensive than individuals. If I had to chose it would be Safeguard for cattle and swine. Very low cost per MG of med. I would add Praziquantel powder for pond fish. Safeguard is the worst tasting stuff ever but my dogs don't mind it at all so it is probably just me. I use the horse paste Panacur powerpac because of the dollars/MG is good and I can tolerate the taste. I watch for sales. All wormers usually go on sale at the end of Fall because farmers and horse owners usually only worm their animals April and October. Whats left after October is over stock. Same with Prazi powder.
The combination of the two works on tapes, flukes, and ascaria. If you only ever took these two you would eventually kill them all. Killing
parasites is a long term program. Considering that one cubic
inch of beef has 10,000
parasite eggs you can see that humans are probably the same.
I always determine the cost per MG before I buy.
