Due to the scarcity of information on Breton horses, the objective was to study hematobiochemical values of this breed. Blood samples were collected from 29 Bretons, males and females, of different ages, in Brasília-DF, distributed into groups, according to age, without distinction of sex (G1): animals from 4 to 9 years old (n=16) and (G2): from 10 to 26 years old (n=13). The horses were also distributed into males and females for comparisons between the sexes. Values for red blood cells, hemoglobin, creatinine, and urea were statistically higher in females. Fibrinogen was higher in males. Lymphocyte values were higher in G1, but mean corpuscular volume, monocytes, neutrophils, and GGT in G2 were higher than G1. The hematocrit value differed between the ages of the females and was higher than that of the males, while the older male animals showed higher values than the young animals. Females presented lower platelet values than males, with older females having higher platelet values than younger females, in the same way as males. G1 females had the highest leukocyte values. The leukocyte values in males of G2 were higher than those of G1. This same behavior occurred for lymphocytes, eosinophils, and creatine kinase. Considering the albumin and aspartate aminotransferase variables, females had the highest values in the group of animals aged 4 to 9 years. Bretons are considered cold-blooded animals, which is consistent with the observed blood count values. However, it is concluded that these horses have biochemical values similar to warm-blooded breeds.
由于关于布列塔尼马的信息稀缺，本研究旨在探讨该品种马的血液生化指标。在巴西利亚联邦区，从29匹不同年龄的布列塔尼马（不分性别）采集血样，按年龄分为两组（不区分性别）：G1组为4至9岁的动物（n = 16），G2组为10至26岁的动物（n = 13）。这些马还按性别分组以进行性别间比较。雌性马的红细胞、血红蛋白、肌酐和尿素值在统计学上更高。雄性马的纤维蛋白原更高。G1组的淋巴细胞值更高，但G2组的平均红细胞体积、单核细胞、中性粒细胞和γ-谷氨酰转移酶高于G1组。雌性马的血细胞比容值在不同年龄之间存在差异，且高于雄性马，而老年雄性动物的值高于年轻动物。雌性马的血小板值低于雄性马，与雄性马一样，老年雌性马的血小板值高于年轻雌性马。G1组雌性马的白细胞值最高。G2组雄性马的白细胞值高于G1组。淋巴细胞、嗜酸性粒细胞和肌酸激酶也呈现相同的变化趋势。考虑到白蛋白和天冬氨酸转氨酶变量，4至9岁动物组中的雌性马值最高。布列塔尼马被认为是冷血动物，这与观察到的血细胞计数结果一致。然而，可以得出结论，这些马的生化指标与温血品种相似。
