This study was carried out to investigate the blood groups(Aa, Ca, Dc, Qa, Ua) and antierythrocyte antibody associated with neonatal isoerythrolysis(NI) in Thoroughbred horses. The blood groups from 1,351(35 stallions, 1,316 mares) Thoroughbred horses tested by serological procedures, and antierythrocyte antibody from 52 mares by indirect antiglobulin test. The blood groups(factor) of Aa, Ca, Dc, Qa and Ua positive were 97.1%, 100%, 91.4%, 82.9%, and 17.1% in stallions, respectively, and were negative 3.5%, 6.2%, 25.1%, 18.3%, and 77.1% in mares, respectively. These mares are considered to be at risk for production of an NI foals. The antierythrocyte antibody was not detected by this technique in all mares. These results suggest that the all breeding mares without blood groups Aa(3.5%) and Qa(18.3%) should be selected a appropriate stallion to prevent of neonatal isretythrolysis during the breeding season in Thoroughbred horses.
