ABSTRACT This study aimed to assess the growth performance of bullfrog (Aquarana catesbeiana) tadpoles subjected to different management practices and diets. Two distinct feeding management strategies were evaluated: broadcast feeding and the use of a trough. Regarding the diet, two formulations were tested: the first involved feed with 28% crude protein (CP) for the initial 30 days, followed by feed with 36% CP for the subsequent 30 days; the second treatment consisted of a commercial feed designed for tropical carnivorous […]

The objective of this study was evaluate the influence of feeding bullfrog tadpoles on commercial feed containing 28% crude protein (CP), on their digestive enzyme performance and activities. The experiment lasted 60 days, at the density of one tadpole/L in boxes containing 30 L water. A hundred and twenty tadpoles at the 25 Gosner stage averaging weight and length was 0.046 g and 6.22 mm, respectively, were used. Survival rate, length, final weight, weight gain, feed consumption, apparent food conversion, […]

The relationship between the quality of dietary crude protein and health of bullfrog juveniles (Lithobates catesbeianus) was evaluated by necropsy and histopathological examination of animals. The histopathology results showed that animals fed different feeds, regardless of CP levels, presented lymphocytary hepatitis, colitis and flattened microvillosities; kidneys with areas of tubulonephrosis and renal tubule calcification; myocarditis and cardiac muscular fiber dissociation. Such injuries suggested a degenerative nutritional process, with development of inflammatory processes spread to all the organs. These findings suggested […]
