Studied was the enzyme constellation, resp., activity of alkaline phosphatase (AP), glutamate-oxaloacetic transaminase (GOT), glutamate-pyruvate transaminase (GPT), aldolase (ALD), leucin-aminopeptidase (LAP), cholinesterase (CE), creatine phosphokinase (CPK), lactate dehydrogenase (LDH), ornithine carbamoyltransferase (OCT), and guanase (G) in a total of 360 clinically normal and lactating and dry cows of the Black-and-White and Simmental crossbreeds. Characteristic quantitative changes were found with GOT, GPT, ALD, LDH, and CPK both over the dry period and over the entire period of lactation. The activity of LAP, AP, OCT, and G was not influenced by the functional status of the animals. In the course of the analyses there were changes in the serum ALD, CE, and GOT, associated with the breed. The enzymes referred to were studied with a view to establishing their normal parameters needed for the practice as the base to demonstrate preclinical disturbances in individual organs and tissues of the cows during pregnancy and the puerperium.
研究了黑白花与西门塔尔杂交的360头临床正常、处于泌乳期和干奶期的奶牛体内的酶组合，即碱性磷酸酶（AP）、谷氨酸草酰乙酸转氨酶（GOT）、谷氨酸丙酮酸转氨酶（GPT）、醛缩酶（ALD）、亮氨酸氨肽酶（LAP）、胆碱酯酶（CE）、肌酸磷酸激酶（CPK）、乳酸脱氢酶（LDH）、鸟氨酸氨甲酰转移酶（OCT）和鸟嘌呤酶（G）的活性。在干奶期和整个泌乳期，GOT、GPT、ALD、LDH和CPK均出现了特征性的定量变化。LAP、AP、OCT和G的活性不受动物功能状态的影响。在分析过程中，血清ALD、CE和GOT出现了与品种相关的变化。对上述酶进行研究，旨在确定实践中所需的正常参数，作为在奶牛妊娠和产褥期期间证明其个别器官和组织临床前紊乱的依据。
