Size doesn't matter that much. Food-to-Meat conversion and the time to market normally matter more, in terms of profitability. Also, the bigger the pigs get, the worse their health will be. Unhealthy pigs don't survive to market, convert their food less efficiently, get rejected at the slaughter house or their meat suffers in quality. Next problem: You want similarly sized pigs for efficient slaughtering. Those "polar bears" won't fit into a standard line. But I guess China isn't that far into their agricultural industrialization yet. They are apparently also playing catch up in terms of food security and management of animal diseases. The last two points are hampered by the general lack of transparency.
