Abstract

The aim of the current study was to evaluate the nutritional value of Lupinus albus processed with exogenous enzymes as replacer of soybean meal. Six hundred European sea bass (11.2 ± 0.0 g) were distributed in 12 tanks and fed the 4 experimental diets containing soybean meal to processed lupin meal at ratios: Control (15 %: 0 %), Lupin 1 (5 %: 7.5 %), Lupin 2 (2.5 %: 10 %), Lupin 3 (0 %: 12.5 %) in triplicate groups for 83 d. The results showed significantly higher final body weight (P = 0.050) and specific growth rate (P = 0.036) and lower feed conversion ratio (P = 0.047) for the group fed the Lupin 1 diet compared to the Control diet. Significantly higher apparent digestibility coefficient of crude protein (P = 0.043) was noted for the group tested with the Lupin 3 diet compared to Control and apparent digestibility coefficient of fat was significantly higher for groups fed the Lupin 1 (P = 0.015) and Lupin 3 (P = 0.000) diets compared to Control. Essential amino acid deposition was higher for the group fed the Lupin 2 diet related to the Control group and the same was observed for trypsin activity in the pyloric caeca (P = 0.031) and intestine (P = 0.016) of fish. Positive effect was observed in the immune status of fish fed the processed lupin meal and no histopathological alterations were determined. Comprehensively, the results proved the potential of processed lupin meal at 12.5 % to totally replace soybean meal in feed formulation for Mediterranean aquaculture marine species.

外源酶对欧洲黑鲈水产饲料加工卢平粕营养价值的评价

本研究的目的是评价外源酶加工的白狼疮作为豆粕替代品的营养价值。六百年欧洲鲈鱼(11.2 ±0.0  g)分布在12个坦克和美联储4实验饮食含有大豆加工卢平餐比率:控制(15 %:0 %),卢平1(5 %:7.5 %),卢平2(2.5 %:10 %),卢平3(0 %:结果表明：与对照饲粮相比，饲喂卢平1号饲粮组的末重（P = 0.050）和特定生长率（P = 0.036）显著提高，饲料系数（P = 0.047）显著降低。饲喂卢平3日粮组粗蛋白质表观消化率显著高于对照组（P = 0.043），饲喂卢平1日粮组（P = 0.015）和卢平3日粮组（P = 0.000）脂肪表观消化率显著高于对照组。饲喂卢平2型饲料的鱼必需氨基酸沉积量高于对照组，而鱼幽门盲肠（P = 0.031）和肠道（P = 0.016）胰蛋白酶活性也高于对照组。食用加工过的罗苹粉对鱼的免疫状态有积极影响，未见组织病理学改变。综上所示，12.5 %的罗苹豆粕在地中海海产水产饲料配方中完全取代豆粕的潜力。

期刊介绍： Aquaculture Reports will publish original research papers and reviews documenting outstanding science with a regional context and focus, answering the need for high quality information on novel species, systems and regions in emerging areas of aquaculture research and development, such as integrated multi-trophic aquaculture, urban aquaculture, ornamental, unfed aquaculture, offshore aquaculture and others. Papers having industry research as priority and encompassing product development research or current industry practice are encouraged.
