Bayer launches new treatment for coccidiosis in calves

New Zealand cattle farmers are among the first in the world to have access to a new coccidiosis treatment, with the national launch of Baycox® C by Bayer HealthCare’s Animal Health Division.

Baycox formulations for chickens and pigs are already registered in New Zealand, but this is the first time such treatment has become available for use in calves.


The coccidian parasite, which causes coccidiosis, is widespread throughout New Zealand and can cause severe diarrhoea.

“Baycox C is great news for farmers and vets having to deal with coccidiosis in calves this season,” says Bayer New Zealand Animal Health veterinarian Dr Sarah Weston.

“Young animals are particularly susceptible because it takes time for them to develop immunity.”

Dr Weston says that cattle become infected by ingesting coccidian oocysts from a contaminated environment. The parasite then reproduces in cells lining the large intestine, resulting in bloody diarrhoea, reduction in weight gain and occasionally death in severe cases.

“The great thing about Baycox C is that it treats an outbreak of coccidiosis with a single dose. Furthermore, using Baycox C as a preventative treatment on properties where coccidiosis occurs often, or is associated with weaning, will give the best results.”

For more information on Baycox C, contact your local livestock veterinarian or phone the Bayer Animal Health customer services desk on 0800 652 488.

Baycox® C is registered pursuant to the ACVM Act 1997 No.A9583. See www.nzfsa.govt.nz/acvm for registration conditions.

About coccidiosis

Coccidiosis in cattle is caused by infection with the pathogenic coccidian of the genus Eimeria. Many different species of Eimeria are known to infect cattle.

The most important species related to the clinical presentation of coccidiosis are Emeria bovis and Emeria zuernii; they affect mainly young calves from one to nine months of age. Infected animals may show clinical signs such as watery to haemorrhagic diarrhoea, anorexia, tenesmus and mortality. In some cases, clinical signs are not present but the animals perform poorly compared with unaffected animals.

Coccidiosis can be controlled with a single oral treatment of Baycox® C.
