Abstract

Feeding trial was conducted to investigate poultry by-product meal, blood meal
and feather meal, in feed for juvenile tilapia (Oreochromis niloticus). A control
fish meal feed and four experimental feed where fish meal was replaced at a
fixed 66% with poultry by-product meal, blood meal, feather meal and enzyme
treated feather meal were formulated. All the feeds were fixed to have a target
protein of 30% and 8% fat to make the experimental diets iso-nitrogenous and
iso-caloric. At the end of the 10 week feeding trial, poultry by-product meal
substitution registered better growth performance and feed utilisation than the
other diets and also the control diet with fish meal. Among the feeds with feather
meal and enzyme treated feather meal substitution, feed with enzyme treated
feather meal substitution performed better than the feather meal substituted
feed. Feed with blood meal substitution registered the poorest growth with almost
negligent feed intake. Results of the present study indicate that a feed with 66%
replacement of fish meal protein by poultry by-product meal can result in better
growth and FCR in Nile tilapia.
