The world’s largest breed of ass, the American Mammoth Jack stock was developed in the US through the selective cross breeding of imported European stock with local Native American and Mexican animals.
\n<\/p>\n
Small time breeding of these animals was common for more than 100 years prior to the development of their official registry in 1888. This is an animal developed based on the needs of people in various areas, but mainly for agricultural and transportation. The intention was to create a larger and stronger animal more capable of heavy workloads.<\/p>\n
Selective breeding helped to preserve important traits, but was often limited to stock that was available for use. However, initially the registry attempted to standardize the breed by only including black animals a minimum of 15 hands tall. Over the years, these rigid type lines have blurred and the breed encompasses a number of colors\/ sizes.<\/p>\n
