AHDB Dairy funded PhD gets to grip with new disease: Ischaemic Teat Necrosis (ITN)

PhD scientist and vet Hayley Crosby, explains how you can help with her research into a new and emerging disease in dairy cattle, Ischaemic Teat Necrosis (ITN).

The cause of the disease, how much disease is present in Great Britain and the risk factors associated with the disease are all unknown. Worryingly, there are anecdotal reports of herds with up to 20% of heifers affected and there are no known effective treatments for this disease.

What Is ITN?

ITN presents as a dry, dark red to black area on the skin at the base of the teat (see photos 1 and 2) that may extend down the teat towards the teat end and/or up on to the skin of the udder. These lesions are highly irritable to the cow and can cause her to constantly lick her teats until she has removed them (see photo 3).

Once the teats have been lost the cow is often culled on welfare grounds. The lesion appears to be mostly confined to the skin and does not directly cause mastitis. Mastitis may however occur due to an inability to milk the quarter and secondary infection (see photo 3).

As the cause of bovine ITN is currently unknown, research into this disease is essential.

How Can You Help?

AHDB Dairy are funding work at the University of Liverpool in an attempt to find some answers. To do this we need your help.

Hayley is keen to hear from anyone with experience of the disease no matter how small the information.

Please contact vet Hayley on 07765456529 or via email hcrosby@liverpool.ac.uk.
