Study on Feedstuff Composition of Tadpole Period of Rana chensinensis

Four diets were used and the infuluence of different nutritional structures on the growth and development of tadpole of Rana chensinensis was studied. The results showed that tadpoles fed diet I had the fastest growth rate and took the shortest time to complete metamorphosis Tadpoles fed diet Ⅲ had the largest mean body weight and length after metamorphosis, being 0.317 g and 1.45 cm respectively; The growth rate was the slowest and the time needed for metamorphosis was the longest (39.2 days) and mean body weight was the lightest (0.254 g) when tadpoles were fed diet Ⅳ.Survial rate and metamorphic rate were not different significantly between diets.
