Coccidiosis in rabbits — notes from the field

Seen a fair bit of this lately. Eimeria - intestinal or hepatic, depends on the species. Young ones post-weaning are the usual victims, immune system just isn't there yet.

Transmission is the usual route: feed, water, bedding. Oocysts are tough, no question. You clean one week, they're still there next week. That's the real headache.

Symptoms? Sometimes obvious: diarrhea, scrawny, bloated. Often not. The insidious ones are the animals that just don't gain weight like their penmates. No diarrhea, but they're falling behind. Breeders know what I mean-those rabbits you keep pulling aside, can't figure out why they're not thriving. Could be coccidiosis.

Here's the thing that gets overlooked: subclinical shedders. They look fine. They eat. They breed. But they're contaminating everything. By the time you see blood in the stool or deaths, the whole shed's already exposed.

So what do you do? Routine monitoring. Not because it's a nice idea, but because waiting for symptoms is waiting too long.

We've been using the antibody test more regularly. It's not perfect-antibodies mean exposure, not necessarily active disease-but it gives you a baseline. You test a few animals, you see the pattern. If titers are climbing across the group, you know something's brewing before production drops.

Practical stuff about the test: results in about 10 minutes. Serum or plasma, nothing fancy. Can run it right in the farm office. No special training needed, honestly-I've had farm staff pick it up in 10 minutes.

Management still matters more than testing, though. Clean water lines, keep feeders off the ground, don't crowd them. Sounds basic, but you'd be surprised how often I walk into operations where these things slip. Test results won't fix that.

Anyway, that's the approach lately. Test regularly, watch the trends, don't wait for the textbook symptoms. And for heaven's sake, don't treat based on one test result alone-look at the group, look at the environment.
