| Abstract | The present study was conducted to investigate the utilization of
cooked soybean as dietary protein source in pelleted feeds for the Nile
tilapia ( Oreochromis niloticus ). Dehulled, dry soybean seeds were
boiled at 100 °c for one hour to inactivate the activity of the trypsin
inhibitor. More than 80% of the trypsin inhibitor activities present
in soybean seed were inactivated by boiling. The boiled and unboiled
soybean seed were dried and ground into meals. These two meals and
defatted soybean meal wholly or in combination were included as
ingredients in feeds. The experimental diets contained 30% crude
protein with graded levels of trypsin inhibitor activity achieved by
varied combination of boiled and unboiled soybean. The fish were fed
a fixed daily ration (5% of body weight, on a dry weight basis) for
70 days. A recirculating water system was adopted and natural food
production was eliminated by housing the entire growing units under a
covered shelter. Significantly different growth responses ( P |
