| 摘 要： | 研究了 5组泥鳅分别摄食不同配合饲料后鱼体营养成分的变化 .结果表明 ,摄食配合饲料后 ,粗蛋白质( CP)质量分数基本不变 ,粗脂肪 ( EE)质量分数提高 ,含水率下降 ;蛋白质中氨基酸 ( AA)种类齐全 ,蛋氨基( Met)质量分数最低 ,谷氨酸 ( Glu)质量分数最高 .摄食配合饲料后 ,泥鳅鱼体中 AA、必需氨基酸 ( EAA)更丰富 ,EAA/AA更高 ,其中 ,4 #(摄食 4 #配合饲料 ) AA总量、EAA和必需氨基酸指数 ( EAAI)分别是空白组( CK)的 1.56、1.61和 1.0 4倍 ;2 #(摄食 2 #配合饲料 )营养指数是 CK的 1.32倍 .摄食配合饲料后 ,鱼体蛋白质中人体 EAA达到成人需要量模式 ( FAO/WHO/U NU推荐 ) ,基本满足儿童和婴儿的需要 ,同时保持天然泥鳅所固有的风味和品质 .试验组与 CK中 6类呈味 AA质量分数的变异程度 1.752 % ,属可接受范围 .试验组与 CK脂肪酸组成均以 C12 、C16、C18脂肪酸为主 ,此 3系列脂肪酸占总脂肪酸质量分数的 64.7% - 92 .2 % ,其中又以 1#(摄食 1#饲料 )所占比例最高 ,CK最低

| Abstract: | Change of the nutrition compositions in 5 groups of loach fed with different formulated feeds was detected. It was discovered that the mass fraction of crude protein almost did not change at all, the mass fraction of crude fat was increased and the content of water was reduced. The loach protein contained all kinds of amino acids, and the methionine mass fraction was the lowest while the glutamic acid mass fraction was the highest in proportion. In tested loach, the amino acids and the essential amino acids were more abundant and the EAA∶AA ratio was higher than that of control. The total amount of amino acids, essential amino acids and the index of essential amino acids in test group 4 (4 #) were 1.56, 1.61 and 1.34 times those in control, respectively. The nutrition index of the loach in test group 2(2 #) was 1.32 times that in control. The essential amino acids in the protein were conformable to the adult nutritional requirement pattern (recommended by FAO/WHO/UNU),which also met the nutritional need of children and infants. Meanwhile, the flavor and quality of the natural loach were kept unchanged. In the test groups and the control, the variation of the mass fraction of 6 sorts of flavor creating amino acids was 1.752% in the acceptable range. The fatty acids C 12 , C 16 and C 18 were found to be the main ones in both test and control loach, and accounted for 64.7% to 92.2% of the total fatty acids. The level of these fatty acids was highest in group 1(1 #) and lowest in control. |
