Nutritional analysis of F3 muscles in the breeding of Larimichthys crocea offspring
摘要
Abstract
[Objective]This study aims to explore the impact of selective breeding on the nutritional quality of the muscles of Larimichthys crocea.[Methods]A comparative analysis was conducted on the crude protein,crude fat,moisture,ash,amino acid composition,and fatty acid composition of muscles between the selectively bred F3 generation of L.crocea and the non-selected control group cultured under identical environmental con-ditions during the same period.[Results]The results demonstrated that the crude protein content in the muscles of the selected F3-generation L.crocea was(16.80±0.33)％,which was higher than that of the control group.In contrast,the crude fat content(12.20±0.12)％and moisture content(69.10±0.69)％were lower,though these dif-ferences were not statistically significant(P＞0.05).The content of total amino acid(TAA)and the content of de-licious amino acids(DAA)in the muscles were significantly higher than those of the control group(P＜0.05).The essential amino acid index(EAAI)reached(84.71±0.86)％,which was higher than that of the control group,but the difference was not significant(P＞0.05).The content of polyunsaturated fatty acids(PUFA)in the muscle was(27.63±0.63)％,the content of highly unsaturated fatty acids(HUFA)was(12.79±0.50)％,the content ofΣn-3PUFA was(13.21±0.44)％,and the content of EPA+DHA was(11.70±0.49)％,all of which were signific-antly higher than those of the control group(P＜0.05).The content of Σn-6PUFA was(13.82±0.95)％,which was significantly lower than that of the control group(P＜0.05).[Conclusion]Improvement in the quality of L.crocea by carrying out population selection of L.crocea for the composite multiple traits of body size,body colour and fast growth rate increased TAA,DAA,PUFA,HUF A,Σn-3PUFA and EPA+DHA contents in the muscles.关键词
