The Mong Cai pig is a Chinese domestic pig breed originating in Taiwan. It is a relatively new breed, developed in the early 1990s in response to a need for a breed better suited to the hot and humid climate of Taiwan. As a result, the Mong Cai has a distinctive black and white spotted coat, which helps it to stay cool.

Mong Cai pigs are medium-sized animals, with females weighing between 150 and 190 pounds (68 – 86 kg) and males weighing between 220 and 270 pounds (100 – 122 kg). They are considered to be hardy and have good disease resistance, making them ideal for smallholder farmers in Taiwan.

Mong Cai pigs are also known for their good temperament and mild personalities. They receive training from an early age and can be easily handled. This makes them ideal for small farms and households who may not have the time or resources to train large pigs.

The Mong Cai is a prolific breeder, with sows typically having litters of 10-12 piglets. Their milk production is also above average, with a sow producing around 10 liters of milk per day. As a result, this breed is ideal for smallholder farmers who are looking to supplement their income with a little extra milk or pork production.

Mong Cai pigs are very hardy animals and can live in a variety of climates. They do best in pastures with plenty of shade and access to mud, as they naturally seek out these areas to cool down. The pigs should also be provided with plenty of fresh water, as they are prone to becoming dehydrated in the heat.

The Mong Cai breed has been successful in Taiwan, where it is now the most common pig breed. It is popular among smallholder farmers due to its hardiness, temperament, and economic benefits. As a result, the Mong Cai is now being exported to other parts of Asia, such as the Philippines and Vietnam, where it is becoming increasingly popular.
