Campolina Holsteiner, and American Saddle Horse. Bloodlines from the Mangalarga Marchador, were also added to refine the Campolina. The herdbook was closed in 1934 and the breed standard first defined. In 1938, the Professional Consortium of Campolina Horse Breeders was formed to formally organize the breed, and in 1951 the organization was renamed to the Campolina Breeders Association, the breed standards were formally adopted, with the organization based in Belo Horizonte. There were further updates to the breed standard in 1975 and 1993. There are currently around 85,000 registered Campolina horses, with slightly over 7,300 registered breeders. Around 4,300 mares were
Animal genetic resources for food and agriculture animal genetic resources. In 2009, six years after the completion of the human genome project, cattle became one of the first livestock species to have a fully mapped genome. Some general conclusions from recent molecular studies show that individual breeds only differ by typically 40% in total genetic molecular composition; species differ by about 80% of their genetic material. Additionally, breeds with well-defined and appreciated traits tend to be inbred and have low genetic diversity, while non-descript local populations tend to have high molecular genetic diversity. Characterization of animal genetic resources is a prerequisite for its management. Advances in molecular
