Growth response of Heterobranchus longifilis (Valenciennes, 1840) fingerlings fed raw and boiled Mucuna cochinchinensis seed meal
Feeding trial was conducted in static water to assess the growth of H. longifilis fingerlings fed different I inclusion levels of mucuna seed meal (MSM). Raw and boiled MSM were used in the diets at 10%,20%, 30% and 40% inclusion levels and the performance of fish fed these diets was compared with fish fed afishmeal-based diet which contained 40% protein. All diets were prepared to be isonitrogenous andisocaloric A two by five factorial experiment with three replicates using ten fish of average initial weight1 .46g was carried out. Daily fish ration of five percent body weight was administered two times for eightweeks. The specific growth rate in diets 1 (control) and 6(10% boiled MSM) were similar and significantly(P<0.05) higher than the other dietary groups. The significantly lower growth performance of fish fed dietscontaining higher inclusion levels of both raw and boiled MSM might be due to incomplete elimination ofthe antinutritional factors present in MSM by boiling. Other methods of processing MSM to improve itsnutritive value should be investigated. (7 page document)
