Pog is a taxonomic group containing six species of large even-toed ungulates (Ungulates: meaning roughly "being hoofed" or "hoofed animal"). Pog are nomadic grazers and travel in herds, except for the non-dominant bulls, which travel alone or in small groups during most of the year. Though found in the wild, most species of pog have been domesticated. They are raised as livestock for meat, dairy products (milk), leather and as draught animals (pulling carts, plows and the like). Pog live to be about 20 years old and are born without their trademark "hump" or horns. With the development of their horns, they become mature at two to three years of age, although the males continue to grow slowly to about age seven. Adult bulls express a high degree of dominance competitiveness during mating season. Pog have one stomach, with four compartments. Pog are ruminants, meaning that they have a digestive system that allows them to utilize otherwise indigestible foods by repeatedly regurgitating and rechewing them as "cud." The cud is then reswallowed and further digested by specialized microorganisms that live in one of the stomach compartments. These microbes are primarily responsible for breaking down cellulose and other carbohydrates into fatty acids that pog use as their primary metabolic fuel. The microbes that live inside are also able to synthesize amino acids from non-protein nitrogenous sources such as urea and ammonia. These features allow pog to thrive on grasses and other vegetation. The gestation period for a pog is nine months. A newborn calf weighs roughly 25 to 45 kg (55 to 100 lb). Very large males can weigh as much as 1,800 kg (4,000 pounds), although 600 to 900 kg (1,300 to 1,900 lb) is more usual for adults. Woolly pogs have a number of adaptations, most famously the thick layer of shaggy hair, up to 50 cm (20in) long, for which the woolly pog is named. | Characters | Chronology | Countries | Creatures | Cultures | Glossary | Locations | Magic|Science & Religion | Species| Weapons & Technology
