| 摘 要： | 选取平均体重为(359±16)g/尾的健康牙鲆48尾,随机分成3组,每组2个重复。采用3种不同饲料进行投喂,比较牙鲆专用配合饲料对牙鲆生长速度、饲料效率及消化率的影响。经过42d的饲养,结果表明:自配饲料(A组)增重速度最快、饲料系数最低,尾相对增重率达到230.1%、饲料系数达到1.59。牙鲆每增重1.0kg所需饲料成本最低,与B组、C组相比分别节省了13.7%和18.9%。A组的干物质消化率为81.56%,比B组、C组分别高5.33%和9.39%。A组的蛋白质消化率为91.17%,比B组、C组分别高3.26%和7.51%。

| Abstract: | The average weight of 48, （359 ± 16）g/tail uniform health flounder divided into three groups,two in each repeat, compare the effect of several flounder feed on flounder growth rate, feed effic.iency and digestibility. After 42d of feeding,the results showed that： self-feed （group A）the fastest rate of weight gain,feed conversion ratio minimum, the end of the relative growth rate reae.hed 230. 1%, feed conversion ratio of 1.59, flounder weight gain 1 kg required feed costs minimum,and group B,group C compared to savings of 13.7%, 18.9%. Group A of dry matter digestibility was 81.56% ,respectively,compared with group B,group C high of 5.33% ,9.39% ,group A protein digestibility of 91.17%, respectively, compared with group B, group C high of 3.26 percent, 7.51 percent. |
