Yes! Prevention is the best treatment. Any number of farms, ranches I've seen over the past years as well as seen from photos and/or website pics, have a lot of "attractive nuisances" scattered about...a/k/a clutter, stuff not picked up to keep the place neat. We raise registered Texas Longhorns and Gaited Horses. Several times a week I spend about an hour or less walking our pens, sub-pasture areas searching for nails, scraps of barb wire, and other easily ingestible items. On occasion, I will drive all around the pastures and pick up things that have surfaced, such as bottles, empty cans, or other stuff that has blown in (we have frontage on a US Hwy). Yes, this is a lot of effort and I usually do it after a rain (things seem to come out of the ground after one...lol). Know our method is out of the question for large operations; however, when walking thru or driving thru your pastures, doesn't hurt to stop and pick up stuff that could harm your critters. Lot cheaper than vet bills or damaged, dead livestock.
