Just wondering how many people give these to their newborns when born?

Were you using something else that was not as effective? Did you see the First Defense stop an outbreak?
We struggled with a tough respiratory combo last year even though we treat all calves when they are born. We did have tough weather so I can't say it was a failure in our routine.
