The Kushum breed is one of the top breeds in the structure of horse breeds in the Aktobe region. In terms of numbers, it ranks third after the Kazakh and Mugalzhar breeds. The Kushum breed in the Aktobe region compares favorably with a number of horse-draft factory breeds in terms of early maturity, fertility, high meat, milk productivity, and economy of keeping. This article describes a new intra-breed type, the “Mamyr-Aktobe” type of the Kushum horse breed of the Aktobe population. The structure of the intra-breed type of Mamyr-Aktobe of the Kushum breed includes three factory lines of stallions: ۱۱۸ Krepysh ۳۳-۶۴, ۱۱۶ Grom ۹۸-۵۸, and ۱۳۷ Samotsvet ۷۷-۷۳ tested in ۲۰۱۰ and ۲۰۱۵ (Samotsvet) and patents No. ۱۸۷,۱۸۶ and No. ۵۸۶were obtained for them. Adult stallions of a new intra-breed type are characterized by high measurements and live weight: ۱۵۹.۷-۱۶۵.۳-۲۰۲.۵-۲۱.۰ cm and ۶۲۶.۵ kg and massiveness - ۱۵۳.۸ and exceed the breed standard in live weight by ۱۲۶.۵ kg or by ۲۵.۳%, according to the massiveness index by ۳۱.۸%, and mares, respectively: ۱۵۵.۲-۱۵۹.۱-۱۸۷.۸-۱۹.۸ cm and ۵۳۱.۰ kg and massiveness - ۱۶۵.۲ and also exceed the breed standard in terms of live weight by ۷۱.۰ kg or ۱۵.۴% and terms of massiveness index by ۷.۹%.
