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 to wild. They differ in terms of animal management, animal treatment, environmental impact, and market infrastructure. For some breeds, opportunities for sustainable use are limited. For such breeds, to ensure that their critical genetic diversity is not lost, conservation programs are required. Several approaches for conservation can be applied, including in situ conservation with live animal populations, and ex situ conservation or cryoconservation involving the freezing of genetic materials. In many instances, both of these approached are used in a complementary manner. In order to establish and strengthen these programs, more research on methods and technologies must be undertaken, especially
