Using iodine on animals also where to buy lugols?

Does anyone give Iodine to their animals? I recently got a milk cow and it's recommended to use a teat dip containing iodine. I'm wondering if I can make up my own, using lugol's.

Would using Iodine on a cow translate into any appreciable Iodine in her milk? I'm thinking that would be healthy for her AND an easy way to increase the family's intake at the same time. (Or would it just be a waste since she doesn't drink fluoridated water or store-bought food?)

Also, I'm on my last bottle of 5% Lugols and need more. Where is everybody getting it from now? J Crow?

Thanks,
