Conteúdo: |
Aspects of digestion in juvenile silver catfish Rhamdia quelen fed with four levels of protein (20, 27, 34 and 41%) were studied. The studied traits were digestive enzymes (nonspecific proteases, trypsin, chymotrypsin, amylase and lipase) and weight gain. The experiment lasted 60 days; 160 juvenile catfish with initial body weight of 32 grams were transferred to the experimental system of 500L tanks with re-circulated and thermostatized water. The average weight of silver catfish increased with dietary protein and 41% of crude protein (CP) was accepted as the best one. Gastric protease activity increases with the CP level. The intestinal alkaline protease reached the peak at 27% CP and the highest activities were observed in the anterior section of the gut (AS). The trypsin peak was observed at 34% CP in the AS and medium section of the gut (MS). Amylase and lipase activities were inverse to the dietary CP and the highest values were observed in AS. In conclusion, the digestive enzymes of catfishes are responsive to the dietary protein level. The dietary CP required for highest weight gain of juvenile silver catfish is 41%. |
