The relatively lean meat of conventional breeds is suitable for sales through key wholesale outlets serving the commodity organic pork market. Conventional breeds may be less suita-ble in more free-range or extensive environments as found in Eastern and Southern Europe, where large litter sizes pose a risk for piglet mortality. Also the climatic conditions in these regions may be unfavorable. In cold winters, their low fat cover gives them poor protection against cold and in hot summers their lack of skin pigment makes them sensitive to sunburn.
