Effects of boiled Jatropha kernel meal as a substitute for soybeans meal in diet of African mud catfish (Clarias gariepinus) fingerlings
A feeding trial was conducted in the laboratory for 8 weeks to evaluate the growth response of C. gariepinus fingerlings using boiled Jatropha kernel as the protein source in place of soybean meal. Four experimental diets (40% crude protein) were formulated, three of these diets contained boiled Jatropha kernel meal at varying levels of 0% 10%, 20%, and 30% while the diet without boiled Jatropha kernel meal served as control. Fish fingerlings were fed weekly at 5% body weight. It was discovered that the percentage weight gain was significantly different (p<0.05) among the controlled diet and the experimental diets; specific growth rates were also significantly different (p<0.05) among the controlled diets 3 and 4, but different in diets 1 and 2 with diet 4 (30%) of boiled Jatropha kernel having the highest value. The highest weight gain was recorded in diet 4 containing 30% of boiled Jatropha kernel meal (75.57g), while the least is at 10% inclusion (52.47g). The soybean meal protein increased with increasing boiled Jatropha kernel substitution. Based on the results of this study, it could be concluded that C. gariepinus could tolerate 30% inclusion of boiled Jatropha kernel meal in the diet in place of soybean meal.
