Sixteen lactating dairy cows were submitted to six injections in a four-week interval of either 640 mg prolonged release bST or of 640 mg saline (control, n = 8). The bST-treated animals were pair fed to the control cows, which were fed according to requirements. Fourteen days after each injection, blood samples were derived and analysed for metabolites and hormones. Plasma contents averaged 0.16 mmol/l non esterified fatty acids (NEFA), 2.69 mmol/l glucose, 0.43 mmol/l beta-hydroxybutyrate, 0.024 mmol/l acetoacetate, 78.8 g/l protein, 4.6 mmol/l urea, 0.81 micrograms/l insulin, 44.4 ng/l thyroxine (T4) and 1.41 ng/l triiodothyronine (T3). The bST-application was without effect on the analysed plasma contents.
16头泌乳奶牛每隔四周接受6次注射，每次注射640毫克长效牛生长激素（bST）或640毫克生理盐水（对照组，n = 8）。bST处理的动物与对照奶牛进行配对饲养，对照奶牛按需求饲养。每次注射后14天，采集血样并分析代谢物和激素。血浆含量平均为：0.16毫摩尔/升非酯化脂肪酸（NEFA）、2.69毫摩尔/升葡萄糖、0.43毫摩尔/升β-羟基丁酸、0.024毫摩尔/升乙酰乙酸、78.8克/升蛋白质、4.6毫摩尔/升尿素、0.81微克/升胰岛素、44.4纳克/升甲状腺素（T4）和1.41纳克/升三碘甲状腺原氨酸（T3）。施用bST对分析的血浆含量没有影响。
