Hello. I would like to know how you do things in Australia as well! This is the Auto Feeder 2500 from SolarFeeder, Inc. You can check out solarfeeders.com to learn more about the feeder I am using. I will start using the feeder in a couple of weeks due to a lot I am fencing off. I will be feeding beef heifers to begin with. I will be feeding them an 18% protein local mixed ration. Later in the spring I will have my Holstein show heifers on the feeder, which I feed a high protein ration.
