not to drift too much but I have worked as professional in the horse business for years. In my opinion horses are treated for parasites way more than they need to be . My research into goats has taught me alot bout parasite management because it is a particular problem in that species. I have NEVER in 20 years seen a vet do a fecal on a horse to check parasite load! They just come out 4x a year and use a anthelmentic from a different class each time. Of course 80% of my charges were kept in stalls and dry lots and rarely had opportunity to infect themselves in any substantial way from grazing so I think there is little risk of developing resistant parasites from the flawed managment. but still parasites ought to be easily managed in equines with minimal use of anthelmentics.
The problem arises from a lack of pasture area, and pasture rotation.
The majority of horses are kept on a property with too little pasture to ratote properly for parasite management.
A pature needs to be left ungrazed for a month, and the clods of manure need to be broken up to break the cycle. That typically doesn't happen for many reasons, hence the use of, and rotation of wormers.
Stalled horses that are fed grain and
hay year round have little worry, but the average owner isn't going to buy hay year round, nor can they afford to.
Tetanus is another issue that comes to mind, since my "emergency" tetanus shot not so long ago, after taking a friends mini to the animal hospital with my hands in her mouth to check what was wrong.....but that's another story............
