Plasma corticoids, potassium and sodium, thyroid activity and hemoglobin and hematocrit values were determined at slaughter over a period of four years in 1612 animals representing the following sire groups: Short-horn, Charolais, Simmental, Limousin, Red Angus, Beefmaster, Brown Swiss, Chianina and Jersey. Differences among years and among breeds of sire were significant for all the parameters studied. Hematocrit values were the highest in females and the lowest for entire males, while hemoglobin levels were the lowest in females and the highest for bulls. Plasma corticoid levels were lower for entire males as compared to steers and heifers. Plasma sodium and potassium levels were the highest for females and the lowest entire males. The values reported in this study for several blood components, based on a large number of animals, could serve as clinical guides and as a basis for further research.
在四年时间里，对代表以下父系品种的1612头动物进行屠宰时测定了血浆皮质激素、钾和钠、甲状腺活性以及血红蛋白和血细胞比容值：短角牛、夏洛莱牛、西门塔尔牛、利木赞牛、红安格斯牛、肉牛王、瑞士褐牛、契安尼娜牛和泽西牛。在所研究的所有参数中，年份之间和父系品种之间的差异均具有显著性。血细胞比容值在雌性中最高，在阉公牛中最低，而血红蛋白水平在雌性中最低，在公牛中最高。与阉牛和小母牛相比，阉公牛的血浆皮质激素水平较低。血浆钠和钾水平在雌性中最高，在阉公牛中最低。本研究基于大量动物报告的几种血液成分的值可作为临床指南并作为进一步研究的基础。
