Onyshchenko O. Development of a technology of microalgae suspension production as ecological safe source of micronutrients for poultry production

New approach for developing and introduction of the technology of green microalgae culturing, which is promising for increasing of level of ecological safety and sustainability for poultry farms of different size and type is developed. Proposed method of culturing is based on principle of optical density stabilization and introduction of biogens aliquots in accordance to actual needs of the culture as primary calculated, which provides high rates of actual productivity when system is scaled up. Counting model for determination of actual culture needs for biogens during culturing cycle is developed and verified experimentally and logistical full-scale culturing system model for supporting of the culturing in accordance with stated principles is proposed. Technological basis of biogens transformation is the system is studies, rational technological conditions for implementation for small and big poultry farms are described and potential of decreasing of environmental press produced by the facilities after implementation of the proposed scheme of waste to products transformation is introduced. Relations in boundaries of technological scheme of poultry farm, which define the effectivity of capture of biogens originating from litter and exhaust in case of biogas digesting and microalgae culturing stages presence are determined. Presented model allowing to project rates of environmental press decrease, which are created by small and large poultry farms, after main influence factors.
