The progeny of Arabian horses has several branches, the most well-known of which are al-koheilat, al-abiya'at, al-saqayat, al-hamdaniyat, al-swetiya'at, and al-seibae'liyat. Most of these are available at the Dirab Center. The center, which has 200 horses and about 45 breeders and staff, is affiliated to the Ministry of Agriculture and Water. Meanwhile, last Friday Crown Prince Abdullah Ibn Abdul Aziz, Deputy Prime Minister and Commander of the National Guard, who is also Chairman of the Board of Directors of the Equestrian Club, patronized the annual grand horse race for the Muhammad Ibn Saud Al-Kabeer Cup at the club's racetrack in Riyadh. The cup was won by Yaqoot, owned by the sons of Prince Badr Ibn Abdul Aziz.
