蚕蛹含有相当丰富的蛋白质和脂肪,本实验利用饲养白鼠的生长试验,以测定蚕蛹蛋白质的营养价值。 1.蚕蛹来源: 苏州第一丝厂,用苯提出蛹油后的蚕蛹,经洗涤干燥并磨成粉末,作为饲料蛋白质的唯一来源,经分析测定该脱脂蚕蛹含蛋白质80～85％。 2.受试动物: 以鼠龄约四周的同窝大白鼠(一般体重约60克)作为饲养对象。白鼠品种系向中国科学院生理生化研究所得来。 3.饲养方法: 将同窝白鼠分成三组,分别饲养在特制铁丝笼内,饲以三种不同的食料作为试验。三种饲料的淀粉、脂肪、维生素与无机盐完全相同,唯蛋白质不相同。
Silkworm pupa contains a very rich protein and fat, the experiment using the growth test of the white rat to determine the nutritional value of the protein of the silkworm pupae. 1. Silkworm pupa Source: Suzhou first silk mill, made of benzene pupa oil after the pupa, washed and dried to a powder, as the sole source of feed protein, the analysis determined that the skim silkworm pupa protein 80 to 85%. 2. Animals to be tested: A littermate (about 60 g in general weight) about four weeks old was used as a feeding object. Department of white rat strains to the Chinese Academy of Sciences Institute of Physiological and Biochemical derived. 3. Feeding Methods: The same day white mice were divided into three groups, were housed in a special wire cage, feeding three different food as a test. Three kinds of feed starch, fat, vitamins and inorganic salts exactly the same, only the protein is not the same.
