Hi Jeffrey. Unfortunately this forum is very slow at the best of times! I was excited to find it a couple of years ago and posted under a different name but gave up when I never got any responses from anyone!
What kind of ration are you feeding and how old are your heifers? Also, which brand of feeder is it; I have worked with the De Laval robotic feeders (milk and grain) but generally the software for these feed systems are pretty straightforward to use (once you understand the basics ofcourse!).
Are they beef or dairy by the way? I work in the dairy industry in Australia and am alsways interested to know how people do things elsewhere!
