I installed a watering system on 2 farms this spring to keep the cows in the individual rotational pastures. We have been rotational grazing for years but the cows had to walk up to 1/4 mile for water in the late summer. I laid 3/4 inch black plastic pipe along the fenceline with a faucett for every pasture. The biggest benefit I have seen so far from this effort is the nutrients are staying in the pasture not in the barn yard or lanes. I am also hoping that I can get a little boost of weaning weights out of this project as well. How far does your livestock have to walk to get water?
