Nutritional Quality Evaluation of Feeds Developed from Secondary Raw Material from Fish Processing Industry

Abstract

Fresh head waste of sardine, threadfin bream,
anchovy and tilapia was converted into fish meal
after cooking and pressing. Whole sardine was used
as control sample. Quality analysis of the prepared
meal revealed that the protein content was lower for
sardine waste (43.1%) and higher for tilapia (62.3%).
The fish meal prepared was used as the protein
source for preparing feed along with other ingredients.
Isoprotenous feed prepared was administered
in Wistar strain male albino rats for a period of 31
days and Feed Intake (FI) Protein Efficiency Ratio
(PER) and Feed Conversion Ratio (FCR) was
estimated. Feed intake was more in threadfin bream
waste feed and anchovy waste feed (135.1 g/31 days)
which was significantly different from other feeds.
The acceptance of feed developed from the waste of
fish shows more or less similar to control feed
indicating that the waste can be utilized for the
development of feed for different animals thereby
resolving the problem of environmental pollution.
