Summary: | This study was carried out to evaluate the influences of maggot formulated feed on growth, digestibility, feed
utilization, and body composition of local snakehead Channa gachua. Five practical diets with iso-nitrogenous (40%
protein) and caloric level (3.5 kcal g-1) were determined as 10%, 20%, 30% 40%, and 50% substitution of maggot
to fish meal protein. Results demonstrated that replacement of 30% protein from maggot in the diet produced in the
highest specific growth rate (4.41 %BW day-1). These results were in line with feed conversion ratio (FCR) and protein
utilization (PER) at increasing dietary maggot level from 10% to 30%. Feed digestibility also attained the maximum
level at 30% of maggot substitution. Thirty percent protein substitution from maggot meal exhibited the highest
growth performance, nutrient utilization, and digestibility than other treatments. Dietary inclusion levels of maggot
meal in diet above 30% remarkably influenced the growth, FCR, PER, and digestibility of C. gachua. Regarding
feed price concern, the application of maggot meal may potentially be profitable for snakehead’s fry culture. |
