摘要： 比较网箱养殖点带石斑鱼对宠物级鸡肉粉(简称P‐PBM)和一种畜禽蛋白混合物(由饲料级鸡肉粉、羽毛粉和血粉按质量比６５ ∶ ２０ ∶ １５ 的比例混合而成,简称MM)的利用能力.设５ 组等蛋白(４９％粗蛋白) 、等能(１９ MJ.kg － １ 总能) 饲料:对照饲料中添加５０ .０％ 鱼粉,在其余４ 组饲料中分别加入１５.０％ 、３０.０％ 的P‐PBM 或１３.９％ 、２７.８％ 的MM 替代对照饲料中鱼粉的３０％ 、６０％ ,每个饲料处理设３ 个网箱重复,每个网箱中放养３０ 尾鱼[初始体质量(３３.４ ± ０.１ ) g] ,饲养实验持续１０ 周.结果表明:通过添加P‐PBM 或MM 将点带石斑鱼饲料中鱼粉含量降低到２０.０％ 对鱼摄食、增质量、饲料系数、氮储积效率(NRE) 、磷储积效率(PRE)和鱼体组成无明显的不良影响;利用P‐PBM 部分替代鱼粉后鱼生长速度趋于加快,NRE 和PRE 趋于升高.本实验结果证实P‐PBM 是点带石斑鱼的优质饲料蛋白源,将其与鱼粉搭配使用可提高网箱养殖点带石斑鱼的生长性能和食物利用效率.
Abstract: The potential of malabar grouper ( Epinephelus malabaricus) in utilizing pet‐grade poultry byproduct meal (P‐PBM) and a blend (MM) which was comprised of ６５％ feed‐grade poultry by‐product meal , ２０％ feather meal and １５％ blood meal was examined in a １０‐week net pen experiment . Five isonitrogenous (４９％ crude protein) and isocaloric ( １９ MJ.kg － １ gross energy) diets were established .One diet was formulated to contain ５０.０％ herring meal as control ,and in the other four diets , ３０％ and ６０％ of the fish meal were replaced respectively by either incorporating P‐PBM at １５.０％ and ３０.０％ ,or incorporating MM at １３.９％ and ２７.８％ . Each diet treatment had three replicates . Initial body mass of the experimental fish was (３３.４ ± ０.１) g . The results indicated that reducing dietary fish meal level from ５０.０％ to ２０.０％ , with P‐PBM or MM as alternative protein source , had no significantly negative effect on feed intake , body mass gain , feed conversion ratio , nitrogen retention efficiency (NRE) , phosphorus retention efficiency ( PRE) and whole body composition . Partial replacement of fish meal with P ‐PBM
resulted in enhancement in body mass gain , NRE and PRE . The results above reveal that P‐PBM is an excellent dietary fish meal substitute for malabar grouper ,and using fish meal and P‐PBM in combinationas dietary protein source can enhance growth performance and feed utilization efficiency of malabar grouper reared in net pens .
