Rob, I am very aware of what all the drugs are used for. Not all infections are caused by "parasites," or in the case of this discussion, worms. Most animals suffering parasite loads great enough to cause illness, will also be very succeptable bacterial, protozoal, viral, and even fugal infection as well.
Once again, before we go any further, when I say not treated, I am NOT talking about the type of animals you sell. I am talking about freshly imported CHEAP animals. Your animals are fairly priced for what the comsumer gets, but I wouldn't call them cheap, fresh imports.
When I said my animals receive a minimum of 1 treatment that is exactly that a minimum. If the animals have arrived too soon before a show or an order they receive one at the minimum.
This is where you need to fish or cut bait. Your one treatment animals are prime breeding grounds for antibiotic resistant organisms. You would be better off either not treating them at all, or keeping them until all treatments are done. Loading everything that comes through w/ panacur, is simply nothing more than lip service. It's a "feel good" for you and your customers. I'm not saying you're bad guy in anyway. It's a very common practice, hence the term shotgunning. It's just (IMHO) a very risky practice. Why panacur? Why not panacur, albon, ivermectin, flagyl, and oh yeah let's throw in a dash of Baytril just to be on the safe side. I'll tell you why. Because panacur ( and flagyl in most cases) is a pretty forgiving drug. It's hard to OD an animal w/ panacur, so, many people throw some down the throat of every animal they get to "treat" them.
You (not you personally, but any "you" that does this) get in 200 w.c. balls do 1 or maybe even 10 fecals if you do any at all. Vet says ok we saw some of this, a little of this, and oh yeah this one guys had this. Little panacur, little flagyl and they'll be all set. Treated and ready to rock. WRONG! What about the stuff the other 190-199 were carrying. What about the 10 or so that have a mild bacterial respiratory or intestinal infection. You hit em with some panacur and that does nothing for the stuff that's actually getting them sick. I think shotgunning does more harm than good in the long run. Especially when the shotgunning is not finished. When you don't finish the drugs only the strong "bugs" survive and reproduce. Then guess what, all those strong kick-ass "bug" genes get passed to the next generation. And later when these "bugs" bloom again, panacur ain't gonna cut it. When's the last time you got a penicillian shot? That stuff was a "miracle" drug after WWII but it just doesn't cut it anymore.
Why? Overuse, plan and simple.
I have Vets that have purchased my animals and been happy with the way I treat my animals that they did not even perform further fecals or test.
Ever wonder why not? Because the AREN'T SICK! If it ain't broke don't fix it. Why treat EVERY animal that you get? Is every animal you get sick? NO. So why waste the time? I'll tell you why. So you can say that you treat every animal. It's a selling point, plan and simple. Makes the customer feel good about buying from you, and makes you look like you take better care of your animals than the next guy. You don't give your kid a full course of Augmetin when he/she comes home from summer camp just to be on the safe side. So why "treat" all these animals?
