Two groups of female lambs of one and the same age, breed, and live weight were fed rations differing in type from two weeks to one year of age. The first group were fed concentrates predominantly, and the second group were fed feeds in which roughage prevailed. After the completion of one year of age experiments and biochemical investigations were carried out with both groups. The intestinal content was studied with regard to amino acid nitrogen and glucose, and the enzyme content - with regard to amylase, lipase, protease, and cellulase in the following sections of the digestive tract: reticulum, rumen, abomasum, small intestine, and caecum. An experiment was also carried out with the resorption in isolated intestinal folds of the initial portions of the jejunum and the caecum in which artificial chyme was introduced. Studied was the resorption of water, chlorides, calcium, glucose, fatty acids, and amino acid nitrogen. Differences were found in the enzyme content and composition of the intestinal content of the various portions of the digestive tract as well as in the resorption with the two groups under the effect of feeding of rations of different type.
将两组年龄、品种和体重相同的雌性羔羊，从两周龄到一周岁期间饲喂不同类型的日粮。第一组主要饲喂精饲料，第二组饲喂以粗饲料为主的饲料。在羔羊满一岁后，对两组进行了实验和生化研究。研究了两组羔羊消化道内容物中的氨基酸氮和葡萄糖含量，以及瘤胃、网胃、皱胃、小肠和盲肠等消化道各部位淀粉酶、脂肪酶、蛋白酶和纤维素酶的含量。还进行了一项实验，在空肠起始段和盲肠的离体肠襻中注入人工食糜，研究水、氯化物、钙、葡萄糖、脂肪酸和氨基酸氮的吸收情况。结果发现，不同类型日粮喂养下，两组羔羊消化道各部位的酶含量、肠内容物成分以及吸收情况均存在差异。
