The crude protein levels as well as the activities of various enzymes were studied in certain tissues of fetuses (80th through 114th days of development), piglets of different age groups, and pigs for slaughter. In most of the tissues tested the postnatal activities of Na-K-ATPase were beyond those recorded from fetuses. The highest GOT activities were recorded from the liver, myocardium, and kidneys. Activities were found to rise sizeably in some tissues after birth. The activity of GPT, too, exhibited age-dependent variations. The activity of leucine-aminopeptidase increased strongly after birth in liver and kidneys. Acid phosphatase activity was less markedly influenced by development phases. Those enzymes which are involved in the formation of fructose and glucose (aldolreductase, glucuronate-reductase, and sorbite-dehydrogenase) had their highest activities, all age-dependent, in liver and kidneys.
对胎儿（发育第80至114天）、不同年龄组的仔猪以及待屠宰猪的某些组织中的粗蛋白水平和各种酶的活性进行了研究。在大多数测试组织中，钠钾ATP酶的产后活性高于胎儿记录值。谷草转氨酶（GOT）活性在肝脏、心肌和肾脏中最高。发现在出生后一些组织中的活性大幅上升。谷丙转氨酶（GPT）的活性也呈现出年龄依赖性变化。亮氨酸氨基肽酶的活性在肝脏和肾脏中出生后强烈增加。酸性磷酸酶活性受发育阶段的影响较小。那些参与果糖和葡萄糖形成的酶（醛糖还原酶、葡萄糖醛酸还原酶和山梨醇脱氢酶）在肝脏和肾脏中具有最高活性，且均与年龄有关。
