The Vietnamese ỉ pig is a local breed from Northern Vietnam, now rarely raised due to low economic efficiency and is currently at risk of extinction.
This pig has solid black fur and skin, a relatively small head, fairly short legs, erect ears, wrinkled face, arched back, bulging belly, and a straight tail. Male ỉ pigs mate very early, as early as 3-4 weeks old, and sperm and eggs are capable of fertilization by 40 days old, although anatomically, they only reach maturity at six years old. Female ỉ pigs have 10 teats, reach estrus at 4-5 months old, and have a reproductive capacity of 8-10 piglets per sow per litter. 8-month-old ỉ pigs can reach 50-60 kg.
Advantages: easy to raise because they tolerate humidity and heat well, are hardy, and have delicious meat.
Disadvantages: small size, slow growth, low lean meat content and high fat content (lean meat percentage is usually only 36% while fat accounts for 54%).
