Blood profiling is a helpful tool in detecting the health status, metabolic diseases, nutritional deficiencies, and welfare of animals. Body weights, body temperatures, hematological and serum biochemical parameters, enzymes, and electrolytes in both sexes of farm emus at the beginning of their breeding season (November in Canada), were determined. The reference interval for each analyte was also calculated. Emus have lower body temperatures (37.2 ± 0.2) than other poultry species. There was no significant between-sex difference in BW, body temperature, and all the hematological and enzyme parameters measured. However, females had significantly (P < 0.001) higher serum calcium, phosphorus, albumin, total protein, globulin, and triglyceride levels than males, probably in preparation for egg laying. We also examined our findings in light of their sex-role reversal in incubation and brooding. Contrary to other avian species in which only females incubate and brood, there was no sex difference in the hematological and enzyme parameters measured in emus. We found that emus are similar to other ratite species with respect to the changes in protein, globulin, triglyceride, and calcium levels. The findings from our study contribute to the database for reference emu hematological and serum enzyme, metabolite, and electrolyte values.
血液分析是一种有助于检测动物健康状况、代谢疾病、营养缺乏和福利的工具。在繁殖季节（加拿大 11 月）开始时，测定了农场鸸鹋雌雄两性的体重、体温、血液学和血清生化参数、酶和电解质。还计算了每个分析物的参考区间。鸸鹋的体温（37.2±0.2）比其他家禽物种低。BW、体温和测量的所有血液学和酶参数在雌雄之间没有显著差异。然而，雌性的血清钙、磷、白蛋白、总蛋白、球蛋白和甘油三酯水平明显高于雄性（P<0.001），可能是为产卵做准备。我们还根据鸸鹋在孵化和育雏中的性别反转来检查我们的发现。与其他只有雌性孵化和育雏的鸟类相反，在鸸鹋中，测量的血液学和酶参数没有性别差异。我们发现，鸸鹋在蛋白质、球蛋白、甘油三酯和钙水平的变化方面与其他平胸鸟类相似。本研究的结果为参考鸸鹋血液学和血清酶、代谢物和电解质值的数据库做出了贡献。
