چکیده
A 56-day feeding trial was undertaken to assess the ef-fects of housefly maggots (HM) forms (dried and fresh) as protein sources on growth, feed efficiency, body indices Oreo-chromis niloticus finger-lings. control diet (T0) contained 300 g/kg fish-meal (without HM). Two practical diets with same formula were prepared dried HM (T1) fresh (T2) where 66 % fishmeal replaced. Di-ets fed triplicate groups tilapia (mean ini-tial weight: 10.26 ±0.12 g). There no difference in survival, condition factor, conversion ratio, efficiency ratio. Fish T0 T1 had sig-nificantly increased (P < 0.05) mean final weight (50.25 ±1.39 - 52.24 ±1.03 g), specific growth rate (2.84 ±0.03 2.88 %/day) gain (389.70 ±7.63 402.78 ±8.16 %) compared T2 ones (46.30 ±2.03 g; 2.67 ±0.07 %/day 356.70 ±7.76 respective-ly). Viscerosomatic hepatosomatic index fish significantly higher than those T0. The present findings indicate that form maggot has given best results terms live form. However, did not affect efficien-cy parameters.

This study was conducted to evaluate the effect of different levels of dietary supplementation of Saccharomyces cerevisiae on growth performance, feed utilization and body biochemical composition of Oreochromis niloticus fingerlings. Four diets containing supplementation at levels of 0, 0.5, 1 and 2 g kg−1 were fed to fingerlings of Nile tilapia (5.01±0.21 g) in four replicate tanks twice ...
