Pig show is a judged event or display where pigs compete to win various titles in each category. Pigs are scored on their market quality which includes muscle, fat, and body structure along with qualities they must possess for their specific breed. Other names for a pig show include swine show and hog show. A pig show is frequently part of a larger agricultural show.
History of the pig show
Pig shows started out on farms where the owner and other pig farmers would gather to decide which pig had the best qualities for breeding.
A show is typically divided up into classes so that the judge can study fewer pigs at a time. The structure is made so that there are division champions and reserve champions and ultimately an over-all Grand Champion. 
Swine judging is the process of selectively ordering swine or domestic pigs in order to determine the superior specimen. For market hogs, traits are ranked in order of their importance: Degree of muscling, growth, capacity or volume, degree of leanness, structure and soundness. For maternal line breeding gilts, the traits by order of importance are: Structure and soundness, Growth, Underline quality, Capacity or volume, Degree of muscling, Degree of leanness.
