ABSTRACT: Culture of Rana tigerina and R. catesbeiana was carried out. The objective of this investigation is to study the effects of diets varying in protein concentrations on frogs at various stages. Tadpoles were fed with diets containing 35%, 39%, 43% and 47% protein while froglets were fed with diets containing 21%, 25%, 29% and 33% protein. Both R. tigerina and R. catesbeiana tadpoles fed with diet containing 35% protein concentration achieved the best results with regard to feed conversion (2.00 in both species of frogs). For froglels, diets containing 21-33% protein resulted in relatively similar feed conversion values (2.3-2. 5 in R. tigerina ; 1.7-1.9 in R. catesbeiana).
