It is almost 100pc based on pure Belgian Blue cattle. It represents the ultimate production line for lean beef. High input, high output, but from sums done on the back of an envelope and from the appearance of the farms involved, this beef system can be profitable. The typical Belgian approach is to produce young bull beef of 650-700kg at 15-16 months. At about €2.80/kg liveweight, this represents an output of €1,800-2,000 for each male calf born.
