Maggots were
produced massively through house fly (Musca
domestica) breeding using poultry manure as substrate. The houseflies were
attracted using rotten fowl and were fed with a semi-solid food mixture
(powdered milk, liquid milk and ground sugar). After copulation the female
flies laid eggs in a tray containing moist poultry manure. They 20hr-old larvae
were introduced to a larger poultry substrate tank inside the maggotry for
further good and development. Larvae passed through three instars of
development and finally become bigger and matured .production of maggots were
affected negatively by climate condition (harmattan) .the 4-5 day-old matured
larvae were harvested and killed with hot water of about 1000c for
10 seconds. The maggots
processed and sundried for 2-3 days after which they
were packaged in an airtight container and stored. Little quantity of the
sundried maggots was ground into powder to form maggot meal. Maggot meal sample
was divided into two samples such as big larvae sample (BLS) and small larvae
sample (SLS). Samples were duplicated. The density, proximate composition and
gross energy were determined. The result of the analyses showed that big larvae
were higher in crude protein than the small larvae. An economic analysis was
carried out using the gross margin analysis method to estimate the cost
effectiveness of maggot production. This includes the gross margin or profit,
gross income or output, total variable cost and cost per kg unit of production.
The analyses showed that maggot production is viable, profitable and relatively
low in production cost.
