中文摘要:
      测定了在室内海水流水系统中养殖的花鲈对7种常用饲料原料,宠物级鸡肉粉(P-PBM)、饲料级鸡肉粉(F-PBM)、血粉(BM)、羽毛粉(FEM)、蚕蛹粉(SWP)、豆粕(SBM)和菜粕(RSM)以及1种混合动物蛋白粉(MM = 50% P PBM+20% F PBM+20% BM+10% FEM)的干物质、蛋白质和能量表观消化率(ADC)。实验饲料由70%基础饲料(蛋白质含量为42.0%,能量含量为18.9 MJ/kg)和30%的待测原料组成。基础饲料和实验饲料中均添加1%(质量分数)的Cr2O3作为外源标记物。饲养实验共进行4周。实验期间每天投饵两次,采用虹吸方法收集粪便。实验结果显示:花鲈对P-PBM、F-PBM、BM、FEM、MM、SWP、SBM和RSM干物质ADC分别为61%~87%,蛋白质ADC为80%~96%,能量ADC为75%~93%。其中,花鲈对SBM的蛋白质ADC最高,对MM的蛋白质ADC最低,对BM的干物质和能量ADC最高,对RSM的干物质和能量ADC最低。
英文摘要:
      Apparent digestibility coefficients (ADC) of seven selected feed ingredients, pet food poultry by product meal (P-BMB), feed grade poultry by product meal (F-PBM), blood meal (BM), feather meal (FEM), soybean meal (SBM), rapeseed meal (RSM), silkworm pupa (SWP) and a blend (MM) of P-PBM, F-PBM, BM and FEM, for Japanese sea bass, Lateolabrax japonicus, were measured. A reference diet was formulated to contain 42.0 % crude protein and 18.9 MJ/kg gross energy, and eight test diets were formulated by combining the reference diet and each of the tested ingredients at a ratio of 70∶30. Chromic oxide was added at 1% in the reference diet and test diets as inert marker. During the experiment, the fish were fed the reference diet and test diets twice daily, and fecal sample was collected by siphon two hours after each feeding. Results of the experiment showed dry matter ADC of the tested ingredients ranged within 61%-87%, and protein ADC within 80%-96%, and energy ADC within 75%-93%. ADC of protein of SBM was the highest, and ADC of dry matter and energy of BM was the highest, among the tested ingredients. ADC of protein of MM was the lowest, while ADC of dry matter and energy of RSM was the lowest among the tested ingredients.
