I had an interesting talk with a very knowledgable vet on the subject of overeating.
Just so you know, we don't have a problem with overeating in our herd. The only vaccine our calves get in the spring, at branding time, is Vision 7. We give nothing else because the immune system of the calf takes care of many problems. We do feed a mineral that contains CTC. Start it a couple of weeks prior to calving and feed it til we turn the bulls out.
Anyway, this vet said something very interesting. We have added so much performance to these cattle and the only way they can perform to those levels is to have a good APPETITE. Overeating is caused partly from a good appetite.
Most of the folks around here have eliminated over-eating by being on a good year-round mineral program. There are a few that do give 7-way at birth.
I hate overeating. It is so fustrating. I know, because it used to be part of our sickness problems, so we experienced it first hand at one point.
