This disease is caused by bacteria that often exist within the sheep’s intestine but only cause disease symptoms under certain circumstances such as a change of grazing, exhaustion, sudden dietary changes and dosing with dewormers.
The bacteria in the intestine produce a toxin (poison) which results in death.
It’s symptoms vary as sometimes the goats are found dead while at other times, they either:
(1) appear exhausted, show paralysis and a loss of consciousness and may have labored breathing, salivation and diarrhoea or
(2) have nervous symptoms with convulsions, accompanied by salivation, grinding of teeth and muscle twitches until death.
The Dead Animal: The carcass decomposes quickly and there are haemorrhages on the heart and blood under the skin in the neck region.
The lungs may contain excessive amounts of blood and the heart sac may contain fluid.
The kidneys may appear enlarged, dark red or pale brown and decomposed. They may contain large amounts of blood.
Although this disease occurs more often in sheep, it can be prevented.
Alternatively vaccinate lambs with Enterotoxaemia Vaccine (including a booster injection) and then repeat vaccination annually.
Give 1ml per animal as a subcutaneous injection.
Note: It is often advised that animals first be vaccinated against pulpy kidney before deworming.
Treatment is not possible rather prevent it through proper and recommended vaccination.
