What is the economically important trait in which Chinese pigs excel?

Chinese pigs are particularly noted for their ability to have very large litters, which is a key economically important trait in swine production. This trait contributes significantly to the overall productivity and profitability of pig farming. Larger litter sizes mean that more piglets can be produced from each sow, leading to higher numbers of marketable pigs without needing to increase the number of breeding sows.

This characteristic is especially advantageous in extensive farming operations where the aim is to maximize output with the current breeding stock. Consequently, the increased number of piglets can lead to better returns on investment in breeding, feeding, and overall management costs.

While traits like high disease resistance, rapid weight gain, and exceptional feed conversion are also important in swine production and have economic implications, the ability to produce larger litters directly influences the number of pigs that come to market, making it a critical focal point for producers, especially in regions where maximizing output is essential for sustainability and profit.
