I've read with interest all the worming threads that have appeared in the past few weeks. I've seen the comments on grubs and that it is dangerous to worm too soon, but I still can't understand exactly when it is safe. Most say spring and fall, but I'm having trouble pin pointing the time. Here in SE Kentucky, it's now spring. Grass is beginning to grow, trees starting to leave out, flies are on my cows and temps are in the mid sixties. Is it safe to worm now? Is there something weather wise that I should go by or a sign from nature?
I'm really confused. I read one thread and I think "OK, I'm gonna worm this weekend." Then the next post I think" Oops, better wait a while". Can anyone give a definite time?
By the way, I bought my heifers last November and I don't know if they were wormed previously, but at least one looks to need it.
