ORLAND, Maine — Black, blonde, brindle, red and racing stripe, the Mangalitsa piglets at Joe Brown’s Longshot Revival Homestead in Orland squealed and pranced, rooted in the mud and suckled on their mothers Monday afternoon. The wooly piglets, some of which were only 2 weeks old, don’t all look alike. But they have something in common: They are descended from the heritage pigs that lived at Jerry Ireland’s farm in Swanville. Ireland may face a jury as soon as next month to be tried on 13 counts of animal cruelty.
