两种豆科绿肥对克氏原鳌虾生长及虾肉品质的影响
Effects of Two Types of Leguminous Green Manures on Growth and Meat Quality of Procambarus clarkii
摘要
Abstract
[Objective]The aim of this study is to explore the effects of two leguminous green manure(Vicia villosa Rothvar and Vicia sativa L.)feed on the growth performance and meat quality of Procambarus clarkii.[Methods]The effects of leguminous green manure addition on growth performance,physicochemical properties and tissue structure of crayfish were analyzed after 60 days of feeding with five feed treatment groups(group T1:V.villosa,group T2:V.sativa,group T3:specialized feed,group T4:V.villosa + specialized feed,group T5:V.sativa + specialized feed).[Results]The results showed that the protein contents of V.villosa and V.sativa were 27.80%and 25.00%,the crude fiber contents of both were 22.60%,and the contents of aspartic acid and leucine were relatively high.After 60 days of feeding,compared with feeding the specialized diet(group T3),there was no significant change in the survival rate of crayfish in different groups(76.7%-80.0%,P>0.05),but the mass gain rate increased significantly by 8.13%,32.92%and 27.95%in groups T1,T4 and T5,respectively(P<0.05),and the meat gain rate increased significantly by 9.29%in group T2(P<0.05);the pressurized water loss rate significantly decreased by 20.6%and 18.8%in groups T4 and T5,respectively(P<0.05),and the color and lustre increased to some extent in all groups except for a decrease in the L* value in group T1,and the crayfish meat muscle fiber interstitial space decreased and shrimp meat became more compact in groups T4 and T5.[Conclusion]The feed mixture was better than the specialized feed or leguminous green manure alone,and the growth performance and meat quality of crayfish were better fed by V.sativa + specialized feed than V.villosa + specialized feed.关键词
