Свиньи Польско-Китайской породы, чёрной масти в белых "чулках", с белым кончиком хвоста и белой отметиной на морде.
Живой вес взрослых хряков Польско-Китайской породы, в среднем - 300-320 кг, маток 210-270 кг. Свиньи польско-китайской породы обладают большой скороспелостью и способностью к откорму: в 6 - 7-месячном возрасте откормочники достигают живого веса 110 - 115 кг; ср. убойный вес при мясосальном откорме 84,7% и доходит даже до 86%; оплата корма высокая. К числу недостатков породы следует отнести малую плодовитость: 7 - 9 поросят на опорос; отдельные матки приносят 10 поросят и больше.
Польско-Китайская порода распространена в США и составляет там 40% всего поголовья племенных свиней. В Россию завозили этой породы в ограниченном количестве, и они оказали некоторое влияние на образование Ливенской породы.
