Abstract

In vitro determination of protein digestibility by treating feedstuffs with pepsin-HCl yields results that differ considerably from the precaecal protein digestibility figures. Comparable results were received when the largest polypeptides in the solution obtained after peptic und tryptic treatment were precipitated with CuSO4 + NaOH.

摘要

通过用胃蛋白酶 - 盐酸处理饲料来体外测定蛋白质消化率，所得到的结果与回肠前段蛋白质消化率数据有很大差异。当用胃蛋白酶和胰蛋白酶处理后得到的溶液中的最大多肽用硫酸铜 + 氢氧化钠沉淀时，得到了类似的结果。
