Erythrocyte alloantigen frequencies of draft horses in Japan were investigated to assess blood donor suitability for transfusion. Here, 148 Japanese draft, 69 Percheron, and 65 Breton horses were blood-typed and subjected to an indirect antiglobulin test. Regarding the major immunogenic factors, the rates of Aa- and Qa-negative horses ranged from 0.35 to 0.49 and from 0.82 to 1.00, respectively. The rate of alloantibody-positive horses ranged from 0.12 to 0.35. Although the prevalence of alloantibodies in these horses was higher than that expected naturally, the rates of Aa- and Qa-negative horses were higher than those of some breeds reported previously. The current draft horse population could provide potential candidates for donors, and the obtained information may contribute to the selection of a safe donor for transfusion.
为评估献血马的输血适用性，对日本挽马的红细胞同种异体抗原频率进行了调查。在此，对148匹日本挽马、69匹佩尔什马和65匹布列塔尼马进行了血型鉴定，并进行了间接抗球蛋白试验。关于主要免疫原性因素，Aa阴性和Qa阴性马的比例分别为0.35至0.49和0.82至1.00。同种抗体阳性马的比例为0.12至0.35。虽然这些马中同种抗体的流行率高于自然预期，但Aa阴性和Qa阴性马的比例高于先前报道的一些品种。目前的挽马群体可以提供潜在的献血候选者，所获得的信息可能有助于选择安全的输血献血者。
