History

In 2013, researchers from ISU went around the far-flung barangays of Isabela province to purchase native pigs reared in the communities. These native pigs were then observed to be pure black in color with straight back, while some have white socks with swayed back. Majority, however, were pure black.
In 2016, the researchers decided to focus on selecting and purifying the pure black strain since most of the Isabela native pigs are pure black. Breeding and selection started with phenotypically pure black male and female animals with not less than 12 teats.
ISUbela native pig is the trade name which has been applied to the developed genetic group developed by the Isabela State University (ISU).
