No these are just regular Y tex tags i've used for years. Vet didn't really have a good answer for me said could be some kind of mite issue which sounded odd on pasture and especially clean pasture the cattle get moved about every 1-3 days depending on which field they're on. I don't normally spray cattle with permectrin in a handheld weed sprayer but it was labelled for killing mites, lice, etc. so i sprayed the calves showing hair loss mixed at the rate on the label.
Probably no help but biting black flies and timber flies are absolutely horrible on baby calves born after Memorial Day -esp in environments with trees/brush like you have in the background of a picture. Any amniotic fluid/sac tissue remaining the calf that the cow doesn’t get licked off becomes a biting fly magnet. Dont know if that would affect hair growth from the bald spots? Don’t know if my obs would apply in your situation |
