Perspectivity of Using Different Commercial Preparations for Acceleration of the “Growing” Process of Chicken Droppings

Abstract

In connection with the necessity to speed up the composting process and preserve the nutrients in chicken droppings, this paper considers the possibility of its processing with the help of the biologically active additive “Mefosfon”, the preparations “Gorynych”, “Tamir”, “Udachnuy”, “Doctor Robik” and hydrogen peroxide . The object of the study was the droppings-free chicken manure of the III danger class of “Yaratel’ poultry farm of “Ak Bars Poultry Production Company” branch. The experiments were carried out in the open air in 50 liter insulated polyethylene containers for 2/3 filled with chicken droppings for 45 days (July-August 2018). The doses of the drugs being applied were determined by the instructions for their use or by the results of previously conducted experiments. Control served as a litter without drugs. When conducting model tests, the temperature of the substrate was monitored, the smell level of the test substrate, the initial and final humidity of the chicken manure, the presence of pathogenic microflora in the resulting product were determined. Recycled chicken droppings in all experimental variants and control belonged to the IV class of danger to the environment. Microbiological analysis carried out at the end of the experiment showed that, in the variant containing “Mefosfon” preparation, the content of enterococci and coliform bacteria was the lowest and amounted to 4% and 2%, respectively, of the final content in the control samples, indicating the promise of using “Mefosfon” to reduce the time of maturation and neutralization of chicken manure.
