Several articles have recently been published about the efficiency of fenceline weaning. Sims and I have been practicing this management tool for several years and I can assure any cow-calf producer that it works and works well. Simple to accomplish if the cow herd has been trained in low stress handling practices. Simply gather herd, strip off calves and return calves to original pasture placing cows in adjoining pasture. After seven to ten days we consistently experience one pound per day gain on the weaned calves. No hay, only rangeland grass and a little training cake so that the calves will know how to eat and respond to a man operating a feeder. No dusty pens to deal with and virtually no health issues.
I know of one operator in the area that does not precondition his calves, only fenceline weans and after 10 days ships them to the new owner. The calves have gained around 10 pounds, no longer bawl or walk the fence. On shipping day, he does not have to strip calves, only walks them into the pen sexes them if necessary, weighs and puts them on the truck. Any producer can benefit from this program regardless of size operation. (20 pair or 500 it works.) May be a bit scary the first time, but that becomes a none issue with planning and good livestock management.
