 Both our climate in North Dakota, it's pretty known fact that our cattle need some protection during the winter and traditionally we've done that over time with trees and shelter belts, probably some buildings, windbreak fences that are permanently installed and those are all great options but something new that's started to show up is portable windbreaks and they've been gaining in popularity and there's a number of advantages to having portable windbreaks if you want to keep your cattle out in the fall and winter do some grazing out on maybe some prop land or even some winter pasture you might not have shelter out there and a portable windbreak fence like this can be pretty helpful in that. Another advantage you can winter them in an area like this and then when calving starts these cattle are here will be moved over into a spot where livestock haven't been since last spring these windbreaks will be picked up and moved. Another thing about with the windbreaks you can change the distribution of your manure scattered around by moving the windbreaks and at calving time you can also do that might help with some disease problems. Well there's lots of different outfits that are building windbreak panels, they advertise in the farm papers and there's also places that sell all kinds of materials if you care to build your own. Most farmers ranchers have welders cut and torch so you can pretty well go with what you have and just check those ads several places to sell stuff. If you want a good strong design for these things these are built out of oil field pipe which is quite a bit of that on the market right now and the base of them should be about one and a half times the height to give them some strength and make sure they won't tip over in the wind. It's best to have two fasten together with chains, give them some added support and helps with when the wind from different directions as far as sheltering cattle. Ideally a windbreak should have 20 to 30 percent ferocity or space between panels or boards gives most protection. That would give you protection eight to ten times the height of the panel and as I said these are built out of two and three eighths oil field pipe and a saddle notch like this is much stronger than some that are flattened and then welded together and you can make a little template out of this is a cardboard mailing tube and you just put that on the pipe make your mark with chalk and gives you guidelines to put them together or to run your cut through. Now as far as the framework as I mentioned the oil field pipe pretty readily available some of the panels are built with square tubing. Some people use wood slots here and guard rail. Guard rail is pretty heavy you make some really strong heavy-duty ones. Sheet metal this is called bee decking and I would suggest anywhere from 18 to 22 gauge if you use regular roof panel I don't believe that's strong enough and and cattle will damage it. These screws will go right through the square tubing or oil field pipe for the self-tapping kind pretty durable work really well. As cattle operations have gotten bigger people are wintering cattle out from the yards more chance to get the manure spread out make use of some of that late fall grazing these portable windbreak panels are something that can help remedy some of those problems that she encountered.
