Blister on cows udder

[Lewis]

So a couple of weeks ago notice a cow getting a blister on the back left quarter on her udder. She's fine in her self and it hasn't been causing her discomfort. But today noticed the scab is starting to peel away. Leaving it bloody and raw. As you can see by the pics it only on the rear of her udder and teat. She's milking out fine. Shall I just keep spraying it with terramycin spray or anyone got any other suggestions? Anyone guess what could have caused it?

Ouch. That back left teat looks sore. I don't think you can do much other than spray it with the blue spray.

My guess is that she has rubbed on some sap from something like hogweed that may have caused extreme photo sensitisation.

Keep up with the spray and hopefully it'll clear up soon.

We try to alternate between Fucidin cream and Engemycin spray as the spray alone seems to dry the area out too much sometimes and then the scabs crack. Follow the milk withdrawal advice If not milking in tank then sometimes the purple sprays seem to penetrate deeper. Hopefully the scab on the teat is reducing and not tracking downwards to teat end.

If using Fucidin make sure it is the non steroidal version and not Fuciderm (I made that mistake once)

Well done on the photographs, i did wonder if it was a viral infection? but I don't think the cow would be standing as still for the photographs
Good luck

Is it a dermatitis?

Its bovine herpes,we found the best thing was blisteze,haven't had one for 10 years but get some cold sore cream on the teat as soon as.

My thinking would be dermatitis would have cleared with terramycin, jade mentioned a virus, I'd give bactakil spray a try, good for all sorts of weird and wonderful ailments!

I'd go with eulb on that then because I've never seen that before!

I sent @Flossie shopping for a rake of cures,they must have thought she was a right mess.

thanks for that @eulb will try if we get another one although hopefully we won't. The only reason I would not be totally sure of a virus is that although the teat looks fairly typical, the patch above is in one piece and not 'crunchy' scabs, also the ones we have had have certainly not been happy to have the teat touched/milked

Thanks for the comments. She is getting better everyday with new pink skin in place of the scab. Still just put blue spray on. Lucky it had sent tracked down to the teat end really.

Thanks for the update. Glad to hear she is getting better

Waking up an old thread....did you pull off the scab before applying the cream?

 

[bovine]

That's not herpes, that's some kind of chemical burn causing the skin to slough and die. It will have felt crispy - like a cow with photosensitisation.

There is no legal mechanism for using cold sor cream/Blistex or Fucidin on a food producing animal if you intend to ever milk it again. These products do not have established withdrawal periods. It's a human health risk.

I use sudacream on ewes lambing time when we get the odd ewe with orf on her teats etc! Might be worth giving her a bit of that help keep the skin soft to stop it drying out!
