A weakened supportive musculature in the navel area resulting in intestines protruding through the belly wall is referred to as umbilical hernia, belly rupture, or belly bust (Figure 2). The development of nipples occurs before sexual differentiation begins which, in humans, is during the sixth week of development. In herds where frequency has been high, heritability of liability of scrotal hernia appears to be in excess of 0.5. Pigs: In the animal kingdom, pigs are mammals with pinkish skin coloring and are well-known for the appearance of their snouts and the sounds of their squeals.
