Selenoprotein is a feed additive that can overcome oxidative stress in intensive Pacific white shrimp () culture. This study evaluated the effects of selenoprotein supplementation at various doses on Pacific white shrimp's digestibility, growth, and health performance. The experimental design used was a completely randomized design consisting of four feed treatments, namely, control and treatments with selenoprotein supplementation of 2.5, 5, and 7.5 g kg feed with four replications. Shrimps (1.5 g) were reared for 70 days and challenged for 14 days by the bacteria (10 CFU mL). Shrimps used in the digestibility performance evaluation (6.1 g) were reared until sufficient quantities of feces were collected for analysis. Shrimp supplemented with selenoprotein exhibited superior digestibility, growth, and health performance compared to the control ( < 0.05). The use of selenoprotein at a dose of 7.5 g kg of feed (2.72 mg Se kg of feed) was considered the most effective for increasing productivity and preventing disease attacks in intensive shrimp culture.
硒蛋白是一种饲料添加剂，可克服凡纳滨对虾集约化养殖中的氧化应激。本研究评估了不同剂量添加硒蛋白对凡纳滨对虾消化率、生长和健康性能的影响。所采用的实验设计为完全随机设计，包括四种饲料处理，即对照组以及添加量分别为2.5、5和7.5 g/kg饲料的硒蛋白处理组，每组有四个重复。将体重为1.5 g的对虾饲养70天，并用哈维氏弧菌（10⁶ CFU/mL）攻毒14天。用于消化性能评估的对虾（体重6.1 g）饲养至收集到足够数量的粪便用于分析。与对照组相比，添加硒蛋白的对虾在消化率、生长和健康性能方面表现更优（P < 0.05）。在凡纳滨对虾集约化养殖中，饲料中添加7.5 g/kg的硒蛋白（相当于2.72 mg Se/kg饲料）被认为是提高生产力和预防疾病侵袭最有效的剂量。
