摘要

Compositions of the amino acid and fatty acid in the muscle of the juvenile paddlefish (Polyodon spathula) were assessed after being fed with live feed and formula feed for 60 days. The crude fat content of formula feed group was significantly higher than that of live feed group (P<0.01). However, the muscle moisture and crude protein contents of formula feed group were significantly lower than those of live feed group (P<0.05). Seventeen kinds of amino acids were detected in the muscles of both groups. The total amino acids (TAA), essential amino acids (EAA), half-essential amino acids (HEAA), nonessential amino acids (NEAA), delicious amino acids (DAA) and essential amino acid index (EAAI) concentrations of live feed group were higher than those of formula feed group. Further, fifteen kinds of fatty acids were detected in both groups, including five kinds of saturated fatty acids (SFA), four kinds of monounsaturated fatty acids (MUFA) and six kinds of polyunsaturated fatty acids (PUFA). Concentrations of paddlefish muscle Sigma MUFA, Sigma UFA, Sigma n-6PUFA, docosahexenoic acid (DHA), eicosapentaenoic acid (EPA)+DHA of formula feed group were higher than those of live feed group. Extremely significant differences were observed in the fatty acids (P<0.01) between groups except Sigma n-6PUFA and EPA+DHA (P>0.05). Based on these comparative studies, our data provides better understanding of artificial culture, feed research and resource protection of paddlefishes.
