The latest corn-based ingredient available in the market today is fermented corn protein concentrate (FCPC), which is expected to perform well in shrimp diets due to its nutritional profile and the probiotic properties of the product. The current study was conducted to evaluate the efficacy of FCPC as a replacement for fish meal (FM) in diets of Pacific white shrimps, Litopenaeus vannamei. Graded levels of FCPC (0, 4, 8, 11, 13 and 15 g/100 g) were used to replace fishmeal (16, 12, 8, 4, 2 and 0 g/100 g) in diet, which was evaluated over a 8-week growth trial (initial weight 0.17 ± 0.01 g; n = 3). At the conclusion, no significant differences were detected in growth, FCR, survival or haematological parameters of shrimp (p > 0.05). Results reveals the efficacy of FCPC to replace 100% fishmeal at an inclusion level as high as 15%, without compromising the performances of shrimp. Significant increase in total haemocyte count (THC) and astaxanthin level in shrimp in response to the inclusion level of FCPC was assumed to be due to the probiotic properties of fermented corn and due to the availability of bio-convertible carotenoids in FCPC, respectively.

用发酵玉米蛋白浓缩物替代南美白对虾实际日粮中的鱼粉

目前市场上最新的玉米原料是发酵玉米浓缩蛋白 (FCPC)，由于其营养成分和产品的益生菌特性，预计在虾饲料中表现良好。本研究旨在评估 FCPC 在南美白对虾（Litopenaeus vannamei）的饲料中替代鱼粉 (FM) 的功效。使用分级水平的 FCPC（0、4、8、11、13 和 15 克/100 克）替代日粮中的鱼粉（16、12、8、4、2 和 0 克/100 克）。为期 8 周的生长试验（初始体重 0.17 ± 0.01 克；n  = 3）。结论是，虾的生长、FCR、存活率或血液学参数没有显着差异（p > 0.05）。结果表明，FCPC 以高达 15% 的含量替代 100% 鱼粉的功效，而不会影响虾的性能。对虾中总血细胞计数 (THC) 和虾青素水平的显着增加被认为是由于发酵玉米的益生菌特性和 FCPC 中生物可转化类胡萝卜素的可用性。
