We used protein tubs some last wint. Have one liqiud feed tank with the wheels. Have had it filled when it went empty by the local feed store but it sure of brand. Her grandson put out Loomix in the open top tanks and left them. Thinking about trying it in a few pastures this winter. We have several options on brands in the area. Haven't done any pricing yet. Wanted opinions on which brands were the best, what protein levels to look for. Also can all liquid feed be fed in open top tanks or does some need the wheels to limit consumption. Have received mixed opinions on that. I ask as the top with the wheels has went bad and can't find one to fit the tank and considering removing it so the cattle can eat it. All opinions will be appreciated. I've done some searches again with mixed results and opinions and the one tank we have is all I've ever fed.
