Quality and safety of a plant growth stimulant obtained from poultry by-products

   Poultry farming is one of the most efficiently developing agricultural industries thanks to the high level of technology and automation of enterprises. However, the intensive pace of development in poultry farming leads to several problems; one of the most important among them is the need to dispose of poultry waste. Large poultry farms can produce up to 100 thousand tons of manure annually, which belongs to the 3^rd class of environmental hazards. Recycling manure allows enterprises to avoid penalties and receive additional economic benefits from selling organic fertilisers. Mechanochemical methods are one of the most accessible and effective ways to process livestock waste. Their essence lies in using chemical reagents for disinfection and processing raw materials.

   The object of the study was a new drug with the properties of a growth stimulant, antidepressant, and antistressant obtained by mechanochemical processing of dry bird manure in an acidic environment.

   The safety parameters were analysed in two accredited laboratories: agrochemical and veterinary. The agrochemical laboratory studied such indicators as the mass fraction of dry and organic matter, the activity of hydrogen ions (pH), the mass fraction of nutrients, the content of toxic elements and the presence of radionuclides. The veterinary laboratory analyses included such groups of indicators as parasitic cleanliness, sanitary-bacteriological, and sanitary-parasitological indicators. It has been shown that the leading indicators of the quality and safety of the drug in the working solution meet the requirements for organic fertilisers. For the medication to work effectively, when preparing a working solution, the consumer must strictly follow the instructions and observe safety precautions when working with a substance with a low pH level.
