摘要
乳糖和矿质元素是哺乳仔猪十分重要的营养素,对7日龄的哺乳仔猪乳糖酶研究结果表明:哺乳仔猪乳糖酶的酶活力常数是65.825μg(ONP)/mL.m in,矿质元素钠、铁和钙能促进乳糖酶的酶活力。
Lactose and mineral elements are important nutrients for sucking piglets. As determined in the present study, the enzyme activity constant in the lactase of sucking piglets was 65. 825 μg（ ONP）/mL ·min. Na, Fe and Ca helped to promote the enzyme activity of lactase.
