研究了添加磷(P)、柠檬酸(CA)和甲酸(FA)对黄尾鱼粉(FM)和交替植物蛋白(APP)饲料幼鱼生长及氮、磷负荷的影响。6种日粮分别为F49(490g kg−1 FM)、F49+P(490 g kg−1 FM和5g kg−1无机磷)、F31+CA(310 g kg−1FM含有200 g kg−1 APP和5 g kg−1 CA)、F31+FA(310 g kg−1 FM含有200 g kg−1 APP和4 g kg−1 FA)，F23+CA(230g kg−1Fm含有300g kg−1 APP和5g kg−1 CA)和F23+FA(230g kg−1FM含有300g kg−1APP和4g kg−1FA)。在现场水温22.0~27.0℃条件下，投喂其中一种饲料12周，F49+P组生长最好，F23+CA组最低。F31+CA组的特定生长率和饲料转化率与对照组相近。在APP日粮中添加CA显著提高了P的滞留率，从而降低了P的排泄量。本研究结果表明，在未添加无机磷的低磷植物蛋白源饲料中添加5g kg−-1 CA，可替代70%的FM，从而减少水产饲料对环境的污染。
An experiment was conducted to investigate the effects of phosphorus (P), citric acid (CA) and formic acid (FA) supplementation on growth and loading of nitrogen (N) and phosphorus (P) in juvenile yellowtail fed fish meal (FM) and alternate plant protein (APP) diets. Six diets designated as F49 (490 g kg−1 FM-based), F49 + P (490 g kg−1 FM with 5 g kg−1 inorganic P), F31 + CA (310 g kg−1 FM containing 200 g kg−1 APP with 5 g kg−1 CA), F31 + FA (310 g kg−1 FM having 200 g kg−1 APP with 4 g kg−1 FA), F23 + CA (230 g kg−1 FM containing 300 g kg−1 APP with 5 g kg−1 CA) and F23 + FA (230 g kg−1 FM having 300 g kg−1 APP with 4 g kg−1 FA) were formulated. Yellowtails were fed one of the diets for 12 weeks under on-site conditions at water temperature 22.0–27.0 °C. F49 + P gave the best growth, while F23 + CA the lowest. Specific growth rate and feed conversion ratio of F31 + CA were similar with control group. Addition of CA to APP diets significantly increased retention of P; hence, its excretion was lowered. The results of this study suggest that FM could be replaced up to 70% with the addition of 5 g kg−1 CA to a low P-containing plant protein sources diet without inorganic P supplementation in juvenile yellowtail diets, which in turn would enable a reduction in environmental pollution from aquafeeds.
