They had something at MSU a bit more primative than this but it was different in that instead of tracking the animal it just had a "key" on the animal that allowed it to open up the place where it got its feed.. than they measured the amount of feed taken and weight gain and I guess that is how they did the convesion rates on different diets and such... IT was pretty cool to be honest, at the time I was there they were doing corn vs Barley rations and something else... I can't remember exactly as it was just a tour... Haven't been to a bull testing station ever, just a steer a year place and all be honest, the whole time I was wondering how the TA could say that this steer was a limousinX Angus and this was a a Simangus and this was a Xx croosed with y but this was a z breed and the rest of the kids nodded their heads in agreement... Poor dairy land boy me could only pick out the Herefords. and hef crosses.. OH well, have learned a bit in the 10 years since.
