Ninety-six frogs were housed in 12 boxes and fed diets containing sunflower, olive, corn, or soybean oil for 61 days. A commercial feed (40% protein) was supplemented with 2% of each oil source. At the end of the experiment, animals were analyzed for biometric data, blood and liver biochemistry, meat composition, and fatty acid profiles. The hepatosomatic index (HSI) and visceral fat index (VFI) were similar across treatments, though frogs fed soybean oil showed a higher intestinal quotient (IQ) than those fed olive oil (P<0.05). Liver histology was unaffected by diet, but significant differences were observed in moisture, protein, and lipid levels (P<0.05), while mineral content remained constant. Frogs fed olive oil exhibited higher concentrations of total saturated, monounsaturated, and polyunsaturated fatty acids. This study recommends sunflower and olive oil as beneficial dietary inclusions to optimize growth and fatty acid profiles in juvenile bullfrogs, contributing to sustainable aquaculture practices.
