An organic fertilizer production system for producing organic fertilizer from livestock or domestic animal droppings using Musca domestica larvae (common fly), comprising: - a first breeding processing storage unit to feed or grow hatched larvae in eggs, - a plurality of second breeding processing storage units arranged below the first breeding processing storage unit, - a third plurality of breeding processing storage units arranged below the second plurality of units of breeding processing storage, said cattle droppings being decomposed with the enzyme of said larvae while the larvae are fed into each breeding unit storage unit, and excrete or produce an organic fertilizer base material, - a section of collection to collect said material or organically produced fertilizer base, and - a larval collection section for the collection of the grown larvae, the resulting collected larvae being, as well as said produced organic fertilizer material carried out of the system； characterized in that: - said first breeding processing storage unit has a drop portion adapted to drop the grown larvae onto said plurality of second breeding processing storage units covered with cattle droppings, - each second storage unit for Breeding processing has a fall portion adapted to drop the grown larvae onto said plurality of third breeding processing storage units covered with livestock feces, - said first, second and third breeding processing storage units are adapted to perform the above processing several times to the final breeding processing storage unit, collecting, the larval collection section, the larvae that are dragged out of said final breeding processing storage unit, in which the first, second, third and last united Rearing processes are adapted to allow said larvae to crawl out of said rearing process storage units.Un sistema de producción de fertilizante orgánico para producir fertilizante orgánico a partir de excrementos de ganado o animales domésticos usando larvas de M
