Stunting is a major chronic nutritional disorder that requires effective nutritional interventions to improve growth and metabolic outcomes. This study aimed to analyze the potential of eel (Anguilla bicolor) oil supplementation as a lipid-based nutritional intervention to enhance growth and biochemical profiles in stunted male Wistar rats. A completely randomized design experiment was conducted using 35 male rats, which were divided into seven treatment groups based on different supplementation doses. The observed variables included body weight, body length, hemoglobin concentration, liver function (SGOT–Serum Glutamic Oxaloacetic Transaminase and SGPT–Serum Glutamic Pyruvic Transaminase), kidney function (urea and creatinine), and insulin growth factor-1 (IGF-1) level. The data were analyzed using One-Way Analysis of Variance followed by Duncan’s post hoc-test with a significance level of 0.05 The results showed that eel oil supplementation significantly improved body weight, body length, and hemoglobin concentration (p<0.05), whereas liver enzyme activity and creatinine levels showed no significant differences among groups (p>0.05), indicating maintained organ function in rats. Elevated urea levels observed in stunted rats decreased following supplementation. These findings indicate that eel oil supplementation improves growth-related indicators without adversely affecting liver and kidney function, suggesting its potential as a promising lipid-based nutritional intervention for stunting prevention.
