Coccidia in dairy calves
There is nothing worse than rearing great calves in the shed and then see them go backwards as they start to go outdoors and onto pasture.
With most meals now containing coccidiostats, the signs of this disease don’t become apparent until around eight to 12 weeks of age.
Infection is via the mouth, with the coccidia invading the wall of the intestine, and as they mature and “hatch” the damage to the gut occurs.
The first sign you will see is poor performance, and this can progress to diarrhoea (often with blood in the faeces and calves straining).
Talk to us about how to lower the risk of clinical disease and if you have clinical infection we will treat with Catolyst® or Baycox®.
In 2017, we tested calves post-weaning. On 86% of the properties tested we detected coccidia. The test of a faecal sample is simple, and if detected, it is best to treat the entire group; prevention through early treatment can avoid significant setbacks.
