- Dietary Saccharomyces Cerevisiae and Pseudomonas Aeruginosa Enhance Growth Performance, Nutrient Utilization, Intestinal Morphology, and Hemato-Biochemical Profile in Red Tilapia (Oreochromis sp.). Ntakirutimana, Remy Rahiman, K M Mujeeb Kunjappan, Jishnu Lovejan, Megha Farhath, Aishath Ali Jijina, M P Khana, A R Nikhila Nandhakumar, K Neethu, K V Bigirimana, Anatole The search for effective probiotic alternatives to antibiotics in aquaculture has increased in recent years. This study evaluated the dietary supplementation of Saccharomyces cerevisiae and Pseudomonas aeruginosa on growth, feed utilization, intestinal morphology, and health of red tilapia (Oreochromis sp.) over a 60-day feeding trial. Fish were fed diets containing three graded levels of S. cerevisiae (1, 2, and 4 g kg⁻¹ feed) or P. aeruginosa (1, 2, and 3 mL kg⁻¹ feed), and compared with a control group. Both probiotics enhanced performance and physiological responses compared with the control. The highest inclusion levels (4 g kg⁻¹ for S. cerevisiae and 3 mL kg⁻¹ for P. aeruginosa) yielded superior growth rate, feed efficiency, and intestinal villus development, accompanied by improved muscle protein content and stable hematological profiles. No adverse effects were detected in water quality or fish health. These findings highlight the potential of S. cerevisiae and a non-pathogenic P. aeruginosa strain as promising probiotics for red tilapia culture, demonstrating complementary effects on nutrient utilization and physiological condition.
