【摘要】 在3个以0．5只/m3的密度放养体重为250 g左右的鳖种,分别投喂冰鲜鱼、 30％冰鲜鱼+70％配合饲料的混合饲料和配合饲料。养殖期5个月,各取6尾600 g 左右的雄性商品鳖进行营养成分测定和比较。结果表明:3种鳖的脂肪率、粗蛋白含量和脂肪酸组成差异不显著(P>0．05)。但肌肉中氨基酸总量和鲜味氨基酸含量均极显著地以冰鲜鱼饲料饲喂的鳖为高(P<0．01)。肌肉与裙边组织中的氨基酸总量、必需氨基酸和鲜味氨基酸的结果与饲料中相应的氨基酸含量呈显著的相关关系 (r1=0．7843,r2=0．9062,P<0．01),其结累量随饲料中含量变化而变化。饲料对商品鳖的风味和营养价值有一定的影响。更多还原

【Abstract】 The experiments were conducted to investigate the effect of ice fresh trash fish,formulated feed and mixed feed(30% ice fresh trash fish+ 70% formulated feed) on the nutrient component of Chinese soft-shelled turtle. Cultured for five months, six turtles per group (about 600 g, male) were selected to check nutrient components. The results showed that no significant differences were found between them in percentage of dissected fat, content of crude protein(P>0.05) in muscle and soft apron. However, crude lipid, total amino acids and flavor amino acids in the muscle of turtle fed by ice fresh trash fish were significantly higher than those of others(P<0.01). There was highly relative between the content of total amino acids,essential amino acids and flavor amino acids in muscle and soft apron of turtle and the content of them in feed (r1=0.7843,r2=0.9062,P<0.01).The results showed that there were some effects of feed on the flavor and nutritional value of turtle.更多还原
