Abstract：
This study was performed as part of developing a functional feed ingredient for juvenile Pacific white shrimp (Litopenaeus vannamei). Here we assess the effects of dietary inclusion of a Black Soldier Fly Ingredient (BSFI) from defatted black soldier fly (Hermetia illucens) larvae meal on growth performance, tolerance to salinity stress, and disease resistance when challenged with Vibrio parahaemolyticus or a strain of white spot syndrome virus (WSSV). A control diet was used for comparison with three test diets including 4.5, 7.5, and 10.5% of BSFI (BSFI4.5, BSFI7.5, and BSFI10.5). After 28 days, all diets with BSFI had improved weight gain, feed conversion ratio (FCR) and specific growth rate (SGR) compared to control. Indeed, SGR was significantly improved from inclusion of 4.5% in the diet, whilst FCR was significantly improved at 7.5% (p < 0.05). During the growth trial, survival was not affected by diet. Shrimp health performance was not significantly affected by the diets across the disease and salinity challenges. Overall, the results indicate that the inclusion of BSFI from H. illucens improves the performance of juvenile L. vannamei.
摘要：
这项研究是为太平洋小白虾（凡纳滨对虾）开发功能性饲料成分的一部分。在这里，我们评估了饮食中包含脱脂黑兵蝇（Hermetiaillucens）幼虫粉的黑兵蝇成分（BSFI）对生长性能的影响，对盐度胁迫的耐受性，当受到副溶血性弧菌或白斑综合症病毒（WSSV）的攻击时，以及抗病性。对照饮食用于与包括4.5、7.5和10.5%的BSFI(BSFI4.5、BSFI7.5和BSFI10.5)的三种测试饮食进行比较。28天后,所有含BSFI的饮食都改善了体重增加，与对照相比，饲料转化率(FCR)和特定生长率(SGR)。的确,SGR从饮食中含有4.5%显著改善，而FCR明显改善为7.5%(p<0.05)。在生长试验期间，生存不受饮食影响.在疾病和盐度挑战中，饮食对虾的健康性能没有显着影响。总的来说,结果表明，包含来自H.illucens的BSFI可以改善幼年南美白对虾的性能。
