- Combined and interactive impacts of octacosanol and Saccharomyces cerevisiae on growth, physiological responses, and disease resistance in whiteleg shrimp (Litopenaeus vannamei). Shehata, Akram Ismael El Basuini, Mohammed F Shija, Vicent Michael Alhoshy, Mayada Taher, Abdelnasser Zheng, Xianyuan Zhao, Yongzhen Zeng, Digang Li, Shengkang The development of functional feed additives represents a promising strategy to enhance shrimp performance and resilience in sustainable aquaculture. This study investigated the individual and combined effects of octacosanol and Saccharomyces cerevisiae on growth performance, physiological status, antioxidant capacity, immune response, and disease resistance in Litopenaeus vannamei. A total of 360 shrimp were randomly assigned to four dietary treatments in triplicate and fed for 60 days: a control diet, octacosanol (12 mg/kg), S. cerevisiae (4 g/kg), and a combined treatment (12 mg/kg octacosanol + 4 g/kg yeast). Disease resistance was further evaluated using a waterborne immersion challenge with the pathogenic Aeromonas hydrophila, with survival monitored over 10 days. All supplemented groups exhibited significantly improved growth performance, with OCTA×SC recording the highest final body weight, weight gain, and specific growth rate, alongside the lowest feed conversion ratio, relative to control (p
