摘　　要： 以家蚕原种为研究材料，探讨小蚕用人工饲料育及继代中，蚕生长发育、蚕卵蛋白质质量分数及SOD和CAT活力的变化情况．结果表明：（1）932和芙蓉经过3代的选择，疏毛率分别从14．6％和9．4％提高到52．4％和53．8％，存活率从20．5％、19．2％提高到38．2％、32．0％；而湘晖、7532选择效果不明显．（2）人工饲料育的湘晖和7532的卵蛋白质质量分数都比桑叶育低；而932和芙蓉三代的卵蛋白质质量分数分别保持在52．50～55．00和41．50～52．50mg／g，与桑叶育基本保持不变．（3）蚕卵的SOD和CAT的活力与蚕品种和饲料有关，人工饲料育蚕卵的SOD和CAT活力比桑叶育高． Using the silkworm parent species as material, young silkworm rearing on artificial diet and their descendants were fed with the same diet. The growth and development of silkworms, mass fraction of the protein of the eggs, the activities of CAT and SOD of eggs, were measured, respectively. The results showed that： （ 1 ） 932 and Furong were selected through three generations, and their setal dispersion rates increased from 14.6% and 9.4% to 52.4% and 53.8%, respectively, and the survival rates increased from 20.5%, 19.2% to 38.2%, 32.0%, respectively. But the selection effect of Xianghui and 7532 was not changed significantly ; （2） Mass fraction of the egg protein of Xianghui and 7532 fed by diet was lower than those fed with mulberry leaves. While the mass fraction of egg protein of third generations of 932 and Furong were maintained 52.50-55.00 and 41.50-52.50 rag/g, respectively, which were consistent with those fed with mulberry leaves ; （3） The activities of CAT and SOD of different eggs were related to the varieties and diets. The activities of CAT and SOD of eggs from four varieties fed by diet were higher than those fed with mulberry leaves.
