The trial reported herein investigated the use of maggot meal as a replacement for fish meal in a cassava products-based layers diet. Old laying hens (/* weeks in lay) made up of two hybrids (Isa Brown and Black Nera) were randomly allotted to five iso-energetic and iso-nitrogenous experimental diets such that each dietary treatment was replicated three times with two birds/replicate. All the diets contained whole cassava root meal (WCRM,-3*.,ῌ.,..0 g/kg) as source of energy with soybean meal (SBM) and cassava leaf meal (CLM) (plant protein sources) supplying /*ῌ and ,/ῌ of the total dietary protein respectively. The experimental treatment consists of fish meal (FM) and maggot meal (MM) as animal protein sources supplying the remaining ,/ῌ of the total dietary protein. Additionally, in diet + (FM and MM supplied ,/.* and *ῌ of dietary animal protein respectively), diet , (FM and MM supplied +2.1/ and 0.,/ῌ of dietary animal protein respectively), diet-(FM and MM supplied +,./* and +,./*ῌ of dietary animal protein respectively), diet. (FM and MM supplied 0.,/ῌ and +2.1/ῌ of dietary animal protein respectively) while in diet / (FM and MM supplied * and ,/.*ῌ of dietary animal protein respectively). The diets were fed over an eight-week period. Average daily feed intake, weight gain and feed conversion ratio were not significantly a#ected (P῍*.*/) by dietary treatment although breed of laying bird significantly a#ected (Pῌ*.*/) these indices. Hen-day egg production was significantly influenced (Pῌ*.*/) by dietary treatments. Of all egg quality characteristics investigated, only shell thickness and shell weight were significantly (Pῌ*.*/) a#ected by dietary treatment and breed. In conclusion, the results of this experiment indicated that maggot meal holds promise as a replacement for fish meal in cassava root-cassava leaf-based diets as it could replace /*ῌ of the dietary animal protein supplied by fish meal without deleterious e#ects on egg production and shell strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
