The carpal gland is an important exocrine gland in pigs, functioning mainly through diverticula that release strongly odorous secretions. The size of the carpal gland and the number of diverticula may be related to its function. To measure its size, the gland must be dissected from the foreleg, and this procedure is time-consuming and cumbersome.

Wild boars exhibit alternating black (dark) and yellow (light) longitudinal stripes on their back during their infancy (juvenile stripes), and as adults, they transform into uniform wild-type coat color. Aiming to record the procedure of juvenile stripes disappearing, piglets (WD) with juvenile stripes were produced by crossing a wild boar with Duroc sows, and photos of their coat color were taken from 20 d to 220 d.

In this study, 1028 pigs from six populations were counted for the carpal gland diverticular numbers (CGDNs) on the left (CGDN) and right (CGDN) legs, and their carcass and meat quality traits were assessed. The CGDNs were significantly different among the populations, and Licha Black pigs had a lower CGDN than the Bama Xiang breed.

Shanxia long black pig was derived from an intercross between Berkshire boars and Licha black pig sows, and it was bred as a paternal strain with high-quality meat and black coat color. Although the coat color was black in the F generation of the intercross, it segregated in the subsequent generations.
