The Poultry Waste Management System

Abstract

Wastes Management System is a set of measures to collect, transport, recycle, reuse or dispose of wastes, as well as control over implementation of these processes. In agriculture, the system primarily aims at environmental safety of production by recycling agricultural wastes. Disposal of organic animal wastes is main task of the system. Fresh bird excrement from poultry farms is unsafe for human, being the 3rd class environmental hazard. Proposed by us technology of bird excrement utilization is new, having no analogues in Russia. Based on process of excrement bioconversing by Black Soldier Fly's larvae (Hermetia illucens L.), it solves a number of problems: environment protection from toxic poultry farming's wastes (bioconversion speed: 3.7...7.6 kg/m2/day), production of ecologically clean fertilizers - zoohumus (output: 11.3...14.8% per 1 kg of wastes), and obtaining high-protein food additive for poultry (1.9...3.5 kg of larvae/day/m2). The system is profitable and of low costs: adding Fly's larvae to the poultry's food, consumption of combined feeds can be reduced by 49%; 360 kg of zoohumus per 1m2 is produced by recycling 3 tons of excrement by larvae; selling larvae as high-protein food additive is 28 times as much in contrast to selling excrement as granular fertilizer.
