本实验旨在评价有机酸和植酸酶对黄颡鱼幼鱼的消化系数、生长性能、身体成分、脊椎和血清矿物质含量以及肝脏和血清抗氧化特性的联合影响。本实验使用 900 条黄颡鱼幼鱼，采用完全随机设计，采用 3 × 2 因子排列（0、2 和 4 g kg−1 饲料有机酸以及 0 和 0.2 g kg−1 饲料（1000 IU kg−1 饲料）植酸酶）。每组 50 条鱼一式三份，进行为期八周的饮食治疗。添加植酸酶可提高干物质、蛋白质和磷的表观消化率；最终体重；具体增长率；体粗灰分；体内粗蛋白；体内磷和钙含量；以及椎骨磷和钙含量；但降低了粪磷含量和饲料转化率。然而，有机酸不影响这些参数。膳食植酸酶和有机酸均显着降低血液活性氧（ROS）水平、血清超氧化物歧化酶（SOD）活性和过氧化氢酶（CAT）活性。在添加1000 IU kg−1植酸酶的日粮中添加4 g kg−1有机酸，与血液ROS含量和血清SOD、CAT活性的增加存在显着的交互作用，表明氧化应激增加（P < 0.05）。植酸酶和有机酸对黄颡鱼幼鱼的生长性能、身体组成和植物蛋白源磷的利用效率没有显着的交互作用（P > 0.05）。
This experiment was conducted to evaluate the combined effects of organic acid and phytase on the digestibility coefficients, growth performance, body composition, vertebral and serum mineral contents, and liver and serum antioxidant properties in juvenile yellow catfish. This experiment was conducted using 900 juvenile yellow catfish in a completely randomized design with a 3 × 2 factorial arrangement (0, 2, and 4 g kg− 1feed organic acid and 0 and 0.2 g kg− 1feed (1000 IU kg− 1feed) phytase). Triplicate groups of 50 fish per tank were fed dietary treatments for eight weeks. Phytase addition increased the apparent digestibilities of dry matter, protein, and P; final body weight; specific growth rate; body crude ash; body crude protein; body P and Ca contents; and vertebral P and Ca contents; but decreased the fecal P content and feed conversion ratio. However, organic acid did not affect these parameters. Both dietary phytase and organic acid significantly reduced the blood reactive oxygen species (ROS) level, serum superoxide dismutase (SOD) activity, and catalase (CAT) activity. The addition of 4 g kg− 1organic acid to the diet supplemented with 1000 IU kg− 1phytase caused a significant interaction on the increments of blood ROS content and serum SOD and CAT activities, which indicated increasing oxidative stress (P < 0.05). Phytase and organic acid showed no significant interaction on growth performance, body composition, and utilization of efficiency of plant-protein-source P in juvenile yellow catfish (P > 0.05).
