As we head into winter across northern Australia, we’ll start to see a decline in protein levels in feed and that can increase the risk of botulism in cattle.
Botulism is especially common in phosphorus and protein deficient areas. Cattle chewing bones can be a sign they are lacking phosphorus or protein, however feeding phosphorus alone does not fully protect cattle from botulism.
Bones, carcasses and decaying vegetation can contain the botulinum toxin. Sudden drops in protein in feed can cause cattle to seek out these sources, increasing the risk of disease.
The safest and most effective protection is vaccination. Botulism vaccination is recommended for all herds across northern Australia, with weaning being a great time to vaccinate cattle while they are already being handled in the yards.
A classic symptom of botulism is paralysis of the tongue. Animals may mouth water at a trough but cannot swallow, as they cannot control their tongue.
Another early symptom is hindquarter paralysis. Animals are often found sitting down with their hind legs stretched out and are unable to rise.
Now is a good time to review your herd health and vaccination programs heading into the dry season.
