There's been a lot of conversation on a few forums as to why or why not fecals should be done.
The vet just called me with the fecal results on my four horses, so I am listing WHY one should get them done, setting aside the fact that worms are becoming resistant to wormers:
1. Three of my four horses do NOT need wormed.
2. Naturally the one that needs wormed is my biggest concern. A concern because he is 25 with Equine Metabolic Syndrome, hind gut ulcers, suspected hanging lipomas in the GI tract and he colics a lot, since last March
While he isn't "loaded", his count is high enough the vet said to wait a few weeks until our weather stops having such wide swings.
I am to worm him with Ivermectin at the vet's instructions.
3. Regarding the three that do not need wormed:
3.1 Two of them were last wormed in May with a double-dose of Ivermectin to get rid of Neck Threadworms (there's a couple current threads regarding those:( Before that, they were wormed November, 2011 with Zimectrin Gold.
3.1.1 Horse Number 3 was last wormed November, 2011 with Zimectrin Gold. He never got wormed last Spring for anything because he was on daily aspirin for severely strained ligaments. He also did not have any signs of NTW's. Why poison him?
So the benefit of fecals? (which were all free this go-round):
1. From a mercenary point-of-view, look at the money I saved.
2. From an ethical/health point-of-view, look at the poison I do not needlessly have to put into my horses.
Not having worm issues (and minor ones where there is an issue) is the best news I've had for months. It's something I always took for ho-hum granted but lately, it's something to crow about in my horse-barn-now-turned-equine-skilled-nursing-facility
I know some vets are just stupid about not wanting to do fecals and charge a ridiculous amount of money. It might be best for those horse owners to invest in a lab kit, including microsope, and do your own
