Great Gizmo!!!!!!!!!!! It looks like it's more stress-free for the calves than other methods, too.
Ya really should patent that design, might as well make some moola from your good idea!
On the subject of freeze branding, we found out that it doesn't work that great on ribs, unless the critter is pretty fat......you get splotchy brands, where it shows up better over the bone, and less over the spaces. Just a thought. On hips and shoulders, though, it worked great!
Another trick we learned is to use Everclear instead of the expensive alcohol. Works great, and ya save some more moola!
And about putting the numbered brands on......my dad tried that once, and the brand inspector about had a kineption fit. He said that those numbers could be someone else's brand, and that it wasn't a very good idea.........dad thought a permanent solution would work better than eartags, that tended to get caught in the brush and ripped out.....we found so many over the years, just lying in the brush and you had no idea which cow it actually belonged to.
Just some things to think over............
Have a good one!
