| Abstract | Present study was carried out to produce enriched cassava by
using a simple technology and use the product as a fish
feed. Two different fermentation period with and without
sulfuric acid treatments were designed to find the favorable
end product of enriched cassava. Five diets were formulated
varying in the content of enriched cassava , fish meal and
soybean meal. To evaluate enriched cassava as a feed
for Orechromis niloticus. A feeding trial was conducted in
a recirculating water system for 56 days.
It showed 42 hrs fermentation period without sulfuric
acid resulted in a favorable end product of enriched
cassava when compared to end product of treated sulfuric acid
with 64 hrs fermentation period. End product of 42 hrs
fermentation resulted no significant different in feed conversion
ratio and protein efficiency ratio with control. Results indicate
that It is possible to replace soyabean meal by 25% of enriched
cassava and fish meal may not be necessary if enriched cassava
used as a protein source with other plant protein sources. |
