英文摘要：

[ Objective ] This experiment was conducted to evaluate the effects of glycinin on the growth performance, feed utilization and nutritional composition in the young common carp. [ Method ] The larval common carp [ initial body mass （ 10. 12 ±0. 08 ） g ] and juvenile common carp [ initial body mass （116. 89 ±0. 13） g] were fed with the semi-refined diets of isonitrogenous （crude protein 40% and 36% ） and isocaloric （ total energy 16.9 and 15.2 MJ/kg） food for 8 weeks. The fish were replaced with 0, 3.0% , 6.0% , 9.0% , 12. 0% of glycinin respectively. [Result and conclusion]The results showed that the growth performance of larval and juvenile common carp diversely decreased with different ratios of purified glycinin. The body mass gain and specific growth rate of 3.0%, 6. 0%, 9.0% and 12. 0% groups in the larval common carp significantly decreased compared with the control groups （P 〈 0. 05 ）, but the feed efficiency ratio, condition factor, hepatosomatic index （HI） and viscerasomatic index （VI） had no significant differences（ p 〉 0. 05 ） between the groups. There were no significant differences in the body mass gain, specific growth rate and feed efficiency ratio of 3.0% groups in juvenile common carp compared with the control groups （P 〉 0. 05 ）, but 6.0%, 9.0% and 12.0% groups were significantly higher than that of control groups（P 〈0. 05）. There were no significant differences in the condition fac- tor, hepatosomatic index and viscerasomatic index between groups （p 〉 0. 05 ）. The crude protein con- tent in muscle of larval and juvenile common carp decreased while the increase of replacement ratio on glycinin was observed. There were no significant differences in the crude protein content in muscle of lar- val and juvenile common carp of 3.0% groups compared with control groups （ P 〉 0. 05 ）, but 6.0%, 9. 0% and 12.0% groups were significantly lower than that of control groups（P 〈0. 05）.
