Results indicate that the 75 Holsteiner maternal lineages covered in the study developed from at least eight ancestral founder mares.
Genetic testing reveals that the current breeding population of Holsteiner horses originated from at least eight ancestral founder mares.
The Holsteiner horse, which originated in the marshlands of Schleswig-Holstein in northern Germany, is one of the most popular horse breeds, and is especially known for its showjumping ability.
The maternal lineages receive special attention and are considered important for the breed’s success.
The documentation of maternal lines had already started in the early 1800s. At that time, each mare with unknown parents was defined as a founder mare for a new lineage.

The intelligence of pigs has long been renowned and scientists in the US have now found that they are clever enough to be able to use computer joysticks.
Researchers from Purdue University in Indiana said they were able to train four pigs to carry out a joystick operated video game task to get treats.
The pigs success rate in the task was described by researchers as remarkable, and indicative of their behavioral and cognitive flexibility.
