蚕豆 (Vicia faba) 是一种具有良好潜力的豆类，之前已在鱼类中进行过测试，取得了一些有希望的结果。本研究旨在确定与商用蛋白质来源（例如大西洋鲑鱼（Salmo salar）中的 FM 和大豆浓缩蛋白 (SPC)）相比，空气分级蚕豆浓缩蛋白（BPC，粗蛋白含量为 615 g kg(-1)）是否可以改善或有利生长性能、身体成分和肠道健康。该试验采用混合物设计方法，研究了采用不同 FM/SPC/BPC 比例配制的 16 种饲料的性能。使用平均重量为1.47克的鲑鱼作为模型。该试验持续八周，还包括高FM（560 g kg（-1））和高脱脂豆粕（SBM，360 g kg（-1））饲料分别作为阴性和阳性对照，以评估远端肠道的肠炎。确定了对生长性能、身体营养成分、存活和鱼类健康（特别是肠道组织学）的影响。结果最终表明，BPC 的总添加量范围为 50 至 200 g kg(-1)，部分取代 SPC 和/或 FM，在鱼类生长性能和营养成分方面显示出最大的有益潜力，可增加生长、蛋白质含量、脂肪含量和灰分。除了有利的全身成分参数外，还发现饲料中添加低于 340 g kg(-1) 的 BPC 不会造成有害影响，例如在喂食高豆粕对照的鱼中观察到的肠炎。高含量的BPC（447.2 g·kg(-1)）引起了轻微的炎症，但没有高SBM饲料引起的严重。这项筛选研究的结果表明，源自蚕豆的 BPC 可以成为大西洋鲑鱼饲料中有价值的替代蛋白质来源。这些数据提供了一个平台，可以结合 FM 和 SPC 对 BPC 含量水平的最佳范围进行建模，以便进一步研究商业相关的鱼类和条件。 (C) 2015 Elsevier B.V. 保留所有权利。
Faba bean (Vicia faba) is a legume with good potential that has previously been tested in fish species with some promising results. The present study aimed to determine whether an air-classified faba bean protein concentrate (BPC, 615 g kg(-1) crude protein content) could offer improved or favourable growth performance, body composition and gut health compared to commercially used protein sources such as FM and soy protein concentrate (SPC) in Atlantic salmon (Salmo salar). The trial investigated the performance of 16 feeds formulated with varying FM/SPC/BPC proportions using a mixture design approach. Salmon parr of average weight of 1.47 g were used as a model. The trial lasted eight weeks and also included high FM (560 g kg(-1)) and high defatted soybean meal (SBM, 360 g kg(-1)) feeds as negative and positive controls respectively, for the assessment of enteritis in the distal intestine. The effects on growth performance, body nutrient composition, survival and fish health, specifically gut histology, were determined. The results demonstrated conclusively that total inclusion levels of BPC ranging from 50 to 200 g kg(-1), partially replacing SPC and/or FM, displayed the greatest potential to be beneficial in terms of fish performance and nutrient composition with increased growth, protein content, fat content and ash. In addition to favourable whole-body composition parameters, it was found that inclusions of BPC below 340 g kg(-1) of feed did not cause detrimental effects such as the enteritis observed in fish fed the high soybean meal control. High inclusion level (447.2 g kg(-1)) of BPC caused a mild inflammation that was not as severe as that caused by the feed with high SBM. The results of this screening study indicate that BPC derived from faba beans can be a valuable alternative protein source in Atlantic salmon feeds. The data provided a platform to model the optimum range of BPC inclusion levels in combination with FM and SPC for further investigation in commercially relevant fish and conditions.
