Austrian Warmblood and Arab-bred stallions to achieve their cavalry goals. Born in Syria in 1830, the part-Arabian horse Shagya became the most famous of these Arabian-bred stallions. He came to Bábolna in 1836 and founded a strain of light cavalry and carriage horses which were taller and heavier than purebred Arabians, but which retained distinct Arabian type. A chestnut Arabian named Gidran followed soon after, crossed on mares who were more Thoroughbred in type. Respectively, these two sires founded the Shagya Arabian and Gidran Anglo-Arabian breeds. The Nonius, Furioso-North Star, Shagya, Gidran, and several other strains are often collectively referred to as
Animal genetic resources for food and agriculture sustainability of a breed and therefore to the potential for successful conservation activities." The Pantaneiro cattle of Brazil are only one example of many at risk of extinction. Despite the importance of animal genetic resources, their diversity has been continually decreasing over time. "Factors as causes of genetic erosion: One of the greatest threats to livestock diversity is pressure from large-scale commercial production systems to maintain only high-output breeds. Recent molecular studies have revealed that the diversity of today's indigenous livestock populations greatly exceeds that found in their commercial counterparts. Climate change and its impact on livestock is being studied.
