22 December 2018 The Horse | All the different toxin serotypes pro- duce the same clinical signs, she says, but you can distinguish them in the lab if you submit blood for testing. That can be important for epidemiological purposes— studying disease incidence, distribution, and control—and for knowing whether the vaccine might be protective. Other preventive measures Johnson suggests include: ■ Finding out where your hay comes from (region and harvest practices used). If it's from an endemic area, vaccinate your horse. C. botulinum is anaerobic (not requiring oxygen), with certain moisture and temperature needs. It's most frequently associated with large round bales that have been harvested or stored improperly. Don't feed hay that looks moldy or smells "off." ■ Keeping areas around feeders clean. Some outbreaks have occurred in par- ticularly wet periods when horses have been picking at hay that has mixed with mud. ■ Watching for rodent or other carcasses in your hay. ■ Avoiding feeding fermented feeds such as haylage and silage, which are more likely to be contaminated with C. botu- linum than nonfermented forages. Clinical signs Botulism frequently causes clinical signs similar to colic: lying down, not eating, and appearing distressed—sweating and shaking—while standing. Case horse A 5-year-old Thoroughbred mare from a nearby race training facility presented with typical coliclike signs. Johnson's evaluation and diagnosis She was trembling, sweating, looking very Dire Diagnoses Horses with botulism often want to lie down and can become recumbent if they ingest a lot of toxin.
