TB from cow colostrum

[Rebecca Louise]

I hope this isn't a stupid question, but if you feed cow colostrum to lambs or goat kids, is there a risk that they could get TB if it came from an affected cow / herd? I can't find a clear answer on the internet, although it does seem like Johne's can be spread that way.

Reactor cow here reared her own calf to weaning, prior to reacting....it has tested clear consistently.

Johnes (Mycobacterium avium subspecies paratuberculosis) or just MAP and TB (M. Bovis) are spread in fluids. Fluids include aerosols. They are in the same family of Mycobacterium.

To answer your question I would assume it is possible to transfer Mycobacterium Bovis to the new lamb this way. How the lambs immune system would see that I have no idea. We know in humans that consume dairy products from TB cows can get very sick.
