Growth Performance, Nutrient Utilization of Nile Tilapia Oreochromis Niloticus Fed Housefly Maggot Meal (Magmeal) Diets

Year 2008, Volume: 8 Issue: 1, - , 01.02.2008

Abstract

A 56 day study was carried out to evaluate the growth performance and nutrient utilization of Nile Tilapia fed diets containing housefly maggot meal (magmeal). Three isoenergetic diets respectively containing 31.20%, 34.0% and 36.10 % crude protein were formulated. Fishmeal was replaced partially with magmeal. Results of the study showed a good overall growth performances and status of experimental fish. Standard growth rate was between 2.58 ? 3.08; food conversion ratio ranged from 1.12 ? 1.45; Protein efficiency ratio was between 2.21 ? 2.47, while hepatosomatic Index and condition factor were ranged from 3.08 - 3.14; and 2.47-2.89 respectively. Fish survival was 100%. These recommend the suitability of magmeal in diets for Nile tilapia fingerling. However, the apparent crude protein digestibility of diet 3 (65.71 %) containing highest magmeal dietary inclusion level, decreased significantly compared to diet 1 and 2 (76.26 %, 77.04 %). This may be due to the effect of elevated ash concentration of magmeal used in the diet formulation.
