Procedure; The experiment started 14. June and ended 4. October. In the
experiment were 56 calves that had been fed during the winter at the
farm Skaftholt in Gnupverjahreppur in Southern Iceland. The calves
were approximately 20 months old when put in the experiment. At the
end of the experiment external body measurements were taken, and all
the calves were slaughtered. In addition to carcass weighing and
grading several organs were weighed. A day later carcass measurements
were done.
