Rabbit Mycotoxin Poisoning: Symptoms and Control

1 Disease Traits

Clear seasonality: most cases appear in the hot, humid months of July and August.

Linked to life stage: it strikes lactating does most, then late-pregnant does; pregnant rabbits may abort.

Not contagious.

Drugs barely help: antibiotics cannot control it, so affected rabbits often die.

2 Symptoms

Mostly acute: poor or lost appetite, abnormal droppings that swing between constipation and diarrhea, sometimes mucus on the pellets; staggering, whole-body trembling, limp limbs, a limp ‘mass’ posture, a head that hangs and cannot lift, damp nose and mouth, and wide-staring eyes. Some show subcutaneous bleeding points on the ears or elsewhere. Temperature rises, breathing is rapid, the heart races with irregular rhythm, and most die gradually 2 to 4 days after onset; some thrash and paddle before death.

3 Prevention Measures

Manage feed strictly: never feed moldy feed, store it scientifically under assigned care to avoid dampness and mold. Roughage like peanut-husk meal, peanut-vine meal, and sweet-potato-vine meal mold easily, as does moisture-prone wheat bran; pelleted feed that is not dried promptly or is kept too long also molds.

Control portions and clear leftover feed from troughs promptly, since residue that dampens and molds in the trough is readily eaten and causes poisoning.

In hot humid seasons, add anti-mold agents to feed such as propionic acid and its salts, benzoic acid, sodium benzoate, formic acid and its salts, parabens, citric acid, sodium citrate, calcium lactate, ferrous lactate, fumaric acid, and dimethyl fumarate, all of which work well.

4 Treatment Methods

Stop the current mixed feed at once and replace it with fresh greens.

Support, protect, detoxify, purge, and suppress: give 25% glucose 20 to 40 ml by vein twice daily until recovery.

Add dispersible vitamins to the drinking water at 1.5 times the label dose for 5 days, or give 10% sugar water 50 to 100 ml by mouth daily.

Inject caffeine sodium benzoate 0.5 to 1 ml under the skin to support heart function.

To purge toxins, boil 20 g starch into a paste, mix in 5 to 6 g sodium sulfate, and drench the rabbit to protect the gut lining, cut absorption, and speed elimination.

Inject vitamin C 3 to 5 ml daily for 3 days with a liver-protecting drug.

Feed nystatin, clotrimazole, or garlicin, which are highly effective against mold.

Most rabbits recover quickly once the moldy feed stops and antifungal drugs are given; with these steps, the condition is well controlled within three days.
