摘要

The intestinal evacuation and maximum daily consumption of two formulated diets with different lipid content (6 and 10%) was examined in juvenile grass carp at 28°C. Fish were fed formulated diets to satiety and removed at 1 hour interval for intestine weighing. The study showed that both diets were evacuated from intestine in 12h and the process of evacuation was expressed by linear regression. In the later study of maximum daily consumption, fish were fed formulated diets to satiety four times in a single day. The sum of diet consumption in the day was recorded. The experiment was repeated in 4, 7, 10, 13, 16, 19, 22 day by the same fish. The result showed the maximum daily consumption of two formulated diets is 3.64 ± 0.23 % body weight (416.79 ± 28.84 J/g.d-1) and 3.75 ± 0.16 % body weight (481.73 ± 19.44 J/g.d-1).
