The weight gain and feed conversion of frogs feeding in the
vibrating feeder tray was higher than that of animals feeding
in the linear feeder after day 60 of the study period. In ninety
days of experiment, weight gain (240.48 ± 16.49 g), feed conversion
(1.10 ± 0.01) and the specific growth rate (4.85 ± 0.15%/day)were significantly higher for animals feeding in vibrating feeder
trays compared to those receiving ration and housefly larvae in a
linear feeder. No significant differences in food intake or survival
were observed between treatments (Table 1)
