During a specific part of the truffle production, truffles emit a specific odor. Pigs have a keen sense of smell which allows them to sniff out the expensive crop. They are intelligent and can be trained to look for that specific scent. In addition, pigs are natural rooters. They dig and eat the roots of plants. This makes it easy for them to root for truffles.
