The investigation was carried out on 12 cows and their calves. At the time of 3 months before parturition and 7 days after parturition metabolic alkalosis one provoked with the high protein feed. The laboratory investigations dependent of determinations on the rumen content the pH, NH3, volatile fatty, acids, the protozoa, bacteria, total gas CO2 and CH4. On the arterial and venous blood on determination the pH, BE, sO2, pO2, HCO3 and coefficient of consumption of the oxygen, and on the venous blood the levels of Na, K, Mg, Ca, P, total proteins, albumins and globulins, cholesterol, glucose, bilirubin, alkaline phosphatase and urea. In the colostrum and in milk one determined the pH, potential acidosis--degree SH, proper weight, proteins, dried mas of milk, time of coagulation in the presence of rennin, Na, K, Ca, Cl, total fats and their composition with different fatty acids. No existed truly changes of clinical signs, only feces was sickly. The metabolic alkalosis of cows decreased the consumption of oxygen across the tissue, deficient of the energy, disorders of water-electrolyte and acid-base balances. The calves form cows with metabolic alkalosis delivered also with metabolic alkalosis, with the symptoms of achondroplasia and degeneration of the liver and other organs. Metabolic alkalosis of cows influenced on the quality of colostrum and milk. The colostrum gained from cows with alkalosis caused of disturbance of gastrointestinal tract and diarrhea presence.
该研究对12头母牛及其犊牛进行。在分娩前3个月和分娩后7天，用高蛋白饲料诱发代谢性碱中毒。实验室检查依赖于对瘤胃内容物的pH值、氨、挥发性脂肪酸、原生动物、细菌、总气体二氧化碳和甲烷的测定。对动脉血和静脉血进行pH值、碱剩余、血氧饱和度、氧分压、碳酸氢根和氧消耗系数的测定，对静脉血进行钠、钾、镁、钙、磷、总蛋白、白蛋白和球蛋白、胆固醇、葡萄糖、胆红素、碱性磷酸酶和尿素水平的测定。在初乳和牛奶中测定pH值、潜在酸中毒程度SH、比重、蛋白质、干物质含量、凝乳酶存在下的凝固时间、钠、钾、钙、氯、总脂肪及其不同脂肪酸的组成。临床症状没有真正的变化，只是粪便呈病态。母牛的代谢性碱中毒降低了组织对氧的消耗，能量不足，水电解质和酸碱平衡紊乱。患有代谢性碱中毒的母牛所产犊牛也患有代谢性碱中毒，伴有软骨发育不全和肝脏及其他器官退化的症状。母牛的代谢性碱中毒影响初乳和牛奶的质量。患有碱中毒的母牛所产初乳会导致胃肠道紊乱和腹泻。
