In 2015, Stal Zegwaard was one of the largest breeding farms for miniature horses in Europe. There were more than 300 miniature horses in Rijswijk. At the moment there are about 50 miniature horses in the stable, including the Falabella, AMHA (American Miniature Horse) and NMPRS (Dutch Mini Horse Registration Studbook) breeds.
Stal Zegwaard has a number of approved stallions. It is possible to bring your mare(s) so that they can be covered by a stallion of your choice. Several foals are born every year, all of which meet the strictest requirements. As a result, the foals are loved worldwide and are sold all over the world. The foals come from mares and stallions that have been approved by the associated studbook.
