The number of pigs in Poland is expected to fall by up to 16% by the end of this year, as producers struggle against the high feed costs and low pig prices, says Professor Jan Malkowski at the Polish Institute of Economics and Food Production. Prof. Malkowski added that, while demand for pork in Poland was still high, the extra requirement was being met more by rapidly rising imports than by local production. He expects it will be at least another 12 months before Poland's pork sector shows real signs of a recovery in output.
