1日粮磷脂对大西洋鲑鱼早期发育和生长性能的影响显示文摘研究旨在证实大西洋鲑鱼对日粮磷脂的需求,更好地确定其需要水平和时期。因此,通过给大西洋鲑鱼提供磷虾或大豆卵磷脂探讨磷脂对其的影响。首先饲喂鱼苗含蛋白质55%和脂肪17%的饲粮,通过添加磷虾油或大豆磷脂补充脂肪.根据回归分析设计5个水平,分别为总磷脂1.5%(未添加)、2.6%、3.2%、3.6%和4.2%。在1g(受精后1400°dpf)、2.5g(1990°ape)、5g(2350°dpf)、10-20g(2850°dpf)和二龄鲑(3800°dpf)时进行取样。整体存活率高,说明存活率和饲粮磷脂添加水平呈正相关(r2=0.59—0.72)。磷脂促进了鱼苗的生长,且饲喂磷虾磷脂2.6%和大豆磷脂3.6%的鱼增长最快。鱼苗达到2.5g之前与之后生长模式不同,0-2.5g鱼补充磷虾磷脂2.6%和大豆磷脂3.6%后的生长速率(SGR)显著高于基础日粮(P〈0.05),而2.5g-二龄鲑期间,各处理之间没有差异。饲喂未补充磷脂的日粮,2.5g时发现鱼肠道脂肪变性,患病率达20%,饲喂低水平大豆磷脂日粮的鱼肠道脂肪变性患病率达10%,而喂食磷虾油和高水平大豆磷脂(≥3.2%)后以及在后期阶段,肠邋脂肪变性情况开始消失。在生命早期阶段,鲑鱼对日粮磷脂的要求是一致的。Taylor J F Martinez-Rubio L Pozo J D Walton J M Tinch A E Migaud H Tocher D R 2015饲料博览2015,0,8:2
