Feeds formulated with alternative ingredients for bullfrog tadpoles (Lithobates catesbeianus)

Several foods are available for the formulation of rations in Brazil; however, effectiveness a few these has been evaluated diets bullfrog tadpoles (Lithobates catesbeianus). This study aimed to evaluate alternative (worm meal, peeled banana, pumpkin, and avocado) with different levels crude protein ether extract nutrition obtain best animal performance water quality. In 60 days long experiment, total 480 (stage 25 Gosner table, 1960) an average weight 0.107 ± 0.004 g, were used. The experimental design was completely randomized (DIC) factorial scheme (2x2) four treatments [rations 320 g/kg (CP) 90 (EE); 380 CP EE; T3:320 110 EE] each consisting replicates. To verify normality data, results zootechnical performance, quality, proximate composition subjected Shapiro-Wilk Bartlett tests. Analysis variance (ANOVA) then performed, means compared using Duncan's test at 5% probability. verified not influenced by suggested diets. diet formulated based on easily acquired ingredients can offer EE bullfrog.
