| Summary: | This study was designed to evaluate the use of chicken intestine as a protein
source for red tilapia juveniles (Oreochromis sp.). This study comprises two
experiments. In experiment I, the effect of feeding two types of food each
respectively containing boiled chicken intestine and raw chicken intestine on the
growth of red tilapia juvenile, Oreochromis sp., were studied. The results showed
that the food containing boiled chicken intestine give better growth for the fish
compared to the one containing raw chicken intestine when used in a 100%
substitution for fish meal.
Based on the results of experiment I, the boiled chicken intestine was selected
for experiment II and was incorporated into isonitrogenous (40% protein) and
isocaloric (450 kcal GEI100g) diets to replace 25%, 50%, 75% and 100%
substitution levels of the fish meal protein in the control diet. The test diets were
fed to triplicate groups of red tilapia juveniles, twice a day, for 70 days. The
results showed that increase in the proportion of boiled chicken intestine in the
diets resulted in growth retardation.
Percent total length gain was highest for fish that were fed with the control diet,
followed by those fed with the diet that substituted 50% of the fish meal with
boiled chicken intestine. Percent body weight gain, similarly, was highest for fish
fed with the control diet, followed again by fish that were fed with the diet that
substituted 50% of the fish meal with boiled chicken intestine.
The results showed that red tilapia juveniles fed with the control diet gave the
best growth compared with fish that were fed others diets. Nevertheless, boiled
chicken intestine could still be used as a main protein source to replace up to
50% of fish meal. Beyond and above the 50% substitution of fish meal with
boiled chicken intestine clearly, resulted in stunting growth. |
