The present study examined the dietary substitution effect of chicken by‐product meal (CBM) for fish meal (FM) on growth, feed utilization, body composition, haematology and non‐specific immune responses of olive flounder, Paralichthys olivaceus. Six isonitrogenic and isolipidic experimental diets were prepared. The control (Con) diet contained 650 g/kg FM. One hundred, 200, 300, 400 and 500 g/kg FM were replaced with CBM, referred to as the CBM10, CBM20, CBM30, CBM40 and CBM50 diets, respectively. A total of 400 juvenile fish averaging 14.7 g was distributed into 20 tanks (20 fish/tank) and fed triplicate groups of each diet, except for quadruplicate groups for the Con and CBM30 diets twice daily to satiation for 8 weeks. Arginine, phenylalanine and threonine content of the experimental diets increased with dietary increased substitution of FM with CBM. The experimental diets did not affect survival, weight gain, specific growth rate, feed consumption and feed utilization of fish. The chemical composition, whole body amino acid profiles, haematological variables and non‐specific immune responses of fish were not changed by the experimental diets. These findings suggest that FM up to 500 g/kg can be substituted with CBM without retardation in growth, feed utilization, haematology and non‐specific immune responses of olive flounder.

鱼粉与鸡肉副产物的膳食替代作用对比目鱼的生长，饲料利用率，身体组成，血液学和非特异性免疫反应的影响

本研究检验了鸡副产品粉（CBM）替代鱼粉（FM）对橄榄比目鱼（Oliparathythys olivaceus）的生长，饲料利用率，身体成分，血液学和非特异性免疫反应的影响。制备了六种等氮和等脂实验饮食。对照日粮含650 g / kg FM。用CBM代替了100、200、300、400和500 g / kg FM，分别称为CBM10，CBM20，CBM30，CBM40和CBM50日粮。将总共​​400头平均重14.7 g的幼鱼分配到20个水箱（20条鱼/坦克）中，每种饮食一式三份，除了每天两次重复两次的Con和CBM30饮食至饱食8周。实验饮食中精氨酸，苯丙氨酸和苏氨酸的含量随着FM被CBM替代的饮食增加而增加。实验饮食不影响鱼类的存活，体重增加，比生长率，饲料消耗和饲料利用率。化学成分，全身氨基酸分布，鱼的血液学变量和非特异性免疫反应没有被实验饮食改变。这些发现表明，高达500 g / kg的FM可以被CBM取代，而不会阻碍比目鱼的生长，饲料利用，血液学和非特异性免疫反应。
