Botulism is a disease that has an effect on not merely horses but also a wide variety of animals. It is a tiny microorganism which has been a silent, but dangerous killer, the informal agent identified as Clostridium botulinum. It is closely related to the bacterium that triggers tetanus only it’s more lethal. When the horses have the harmful toxins within the system the incubation time period for the organism is from twenty four hours to a few days.
When it is inside the horses system, the toxins reproduce frequently and rapidly in the horse’s gut. Horses will get botulism in a lot of ways. In foals nearly eight months old, botulism can happen if the bacterium develops in the foal’s intestines. Foals which are maturing well and are also being fed grain are most likely to get into trouble. These kinds of foals are known as “shaker foals” since the muscle weakness from the toxin makes them tremble. From time to time a wound can become contaminated with the bacteria and cause botulism in adults. Fortunately, this can be rare. Far more commonly, botulism happens any time horses eat feed food which contains preformed toxin.
Clostridia grow on food sources that are over a pH of 4.5 and are also in an anaerobic environment. Here they produce toxins. Badly stored haylage is often an excellent atmosphere for disease growth. Water and feed can be infected with the carcass of a dead animal. Any time several horses develop botulism, toxin in feed or water is usually the reason. Several incidents of botulism happen every year after horses eat packaged or bagged round bale haylage. In a few of these outbreaks, the haylage appeared and smelled rotten. On other occasions, the bales did not look as though they were spoiled but horses eating them developed botulism.
In the past, more than 90 % of contaminated horses perished from this condition. The introduction of an antitoxin and good care in helping nursing, drinking, and eating have raised a horse’s potential for survival to nearly 70 percent. Unfortunately, botulism antitoxin isn’t widely accessible, and it’s also expensive. It really works best when used at the beginning of the course of the disease, but too often the first indications of botulism go unnoticed. The antitoxin is effective, but prevention with vaccination is the best method. A fantastic vaccine is now available for at-risk horses in regions with high botulism possibilities.
