Abstract: The study was carried out to identify the impact of probiotics on proximate composition and amino acids of cage reared tilapia Oreochromis niloticus for 120 days. Cage farming was done under four treatments as T₁ (biozyme), T₂ (rapid grow), T₃ (miracure probiotics) and T₄ (control), and each having three replicates. Proximate compositions and amino acids of fish were determined. Proximate composition and amino acid profiles varied significantly (p<0.05) between probiotic treated and nontreated fish. Higher amount of moisture and ash content observed in nontreated tilapia whereas comparatively higher protein and lipid content found in treated than nontreated. Among 14 recorded amino acids, essential amino acids were threonine, methionine, isoleucine, leucine, histidine, lysine, arginine and valine. Nonessential amino acids were aspertic, serine, glutamic, glycine, alanine and tyrosine. Comparatively higher amount of essential and nonessential acids secured in treated tilapia than nontreated tilapia. Therefore, results of the study imply that probiotics may use in tilapia farming to enhance protein and lipid content, which help to increase taste and good smell of fishes.
