Pelage Traits in Neonatal Wild, Domestic and "Crossbred" Piglets1

Abstract

Neonatal wild piglets had greater average pelage weight density and pelage population density—both traits directly related to pelage insulation—than domestic piglets. Furthermore the wild piglet's hair shaft's had a larger medulla and contained more medullary vacuolation; relative medulla size and vacuolation are directly related to pelage insulation by decreasing hair-shaft conductivity. Piglets sired by a wild boar and out of a domestic sow had values for these traits intermediate to wild and domestic piglets.
