Hey thanks for commenting liking and subscribing I appreciate it! I wouldn’t say we have a system but we do have manure catch ponds in the low spots then we pump out those ponds every so often. Our feedlot was built 40 years ago by my dad. We’ve done a lot of work over the years to limit runoff and we have little to none but it also helps to keep the pens clean. We try to keep the concrete along the bunks clean as much as possible. Easier for cattle to get to the bunk and less stress. Thanks again!
