在这项研究中，评估了韩国豆酱、米曲霉发酵豆粕 (F-SBM) 和米曲霉本身的膳食补充剂对幼年鹦鹉鱼（一种海水养殖鱼类）的生长性能、饲料利用率、免疫反应和磷利用率的影响。配制四种等氮和等热量日粮，其中含有 8% 豆粕（对照日粮）、4% Meju（50% 豆粕被 Meju 替代）、4% F-SBM（50% 豆粕被 F-SBM 替代）或 0.08% 米曲霉本身。将四种实验饲料中的一种喂给三组鱼，持续 8 周。饲养试验结束时，生长性能和饲料利用率没有发现显着差异。饲喂米曲霉饲料的鱼的红细胞计数显着高于饲喂对照饲料的鱼。 Meju 饮食中的抗氧化活性显着高于对照和米曲霉饮食。与饲喂对照饲料的鱼相比，饲喂 Meju 和 F-SBM 饲料的鱼血清抗氧化活性在数值上较高，尽管并不显着。饲喂测试饲料的鱼的肝脏超氧化物歧化酶活性显着高于饲喂对照饲料的鱼。各饲料鱼的蛋白质表观消化系数无显着差异。与饲喂对照饲料的鱼相比，饲喂 F-SBM 和米曲霉饲料的鱼的磷吸收在数值上有所增加。这项研究表明，豆粕发酵过程不会损害鹦鹉鱼的生长性能和饲料利用率。发酵过程可以增强豆粕中磷的利用率和鹦鹉鱼的非特异性免疫反应。
In this study, dietary supplementations of Korean Meju, fermented soybean meal (F-SBM) by Aspergillus orvzae, and A. oryzae itself were evaluated on growth performance, feed utilization, immune responses and phosphorus availability in juvenile parrot fish, a marine aquaculture fish species. Four isonitrogenous and isocaloric diets were formulated to contain 8% soybean meal (control diet) 4% Meju (50% soybean meal was replaced by Meju), 4% F-SBM (50% soybean meal was replaced by F-SBM), or 0.08% A. oryzae itself. One of the four experimental diets was fed to triplicate groups of fish for 8 weeks. At the end of the feeding trial, no significant differences were found in growth performances and feed utilization. Red blood cell counts in the fish fed the A. orvzae diet were significantly higher than that of fish fed the control diet. The antioxidant activity in Meju diet was significantly higher than that of the control and A. oryzae diets. Fish fed Meju and F-SBM diets showed numerically higher antioxidant activity of serum compared to that of fish fed the control diet, even though it was not significant. Liver superoxide dismutase activity of fish fed the test diets was significantly higher than that of fish fed the control diet. The apparent digestibility coefficients of protein of fish fed all the diets were not significantly different. Phosphorus absorption was numerically increased in fish fed F-SBM and A. oryzae diets compared to that of fish fed the control diet. This study indicates that the fermentation process of soybean meal does not impair growth performance and feed utilization in parrot fish. The fermentation process could enhance the availability of phosphorus in soybean meal and non-specific immune responses of parrot fish.
