【 摘 要 】

The present work aimed at evaluating the effects of replacement of fish silage on the bullfrog tadpoles diet. A total of five diets was tested as follows: D0- 100% fish meal (FM); D1- 50% FM and 50% acid silage obtained from tilapia filleting residue (AFR); D2- 100% AFR; D3- 50% FM and 50% acid silage obtained from whole freshwater fish (AFF) and D4- 100% AFF. All treatments were carried with four replicates and a completely randomized design. The parameters analyzed for both performance and body composition of the tadpoles showed that the best results were obtained with diets D0 , D1, and D3. The results did not differ statistically among themselves, which indicates that fish meal can be replaced, up to 50%, by acid silage from tilapia filleting residue or whole freshwater fish.
