چکیده
The increase in the population on planet leads to an volume of food production. high demand for poultry products a rapid number broiler chickens both world and Ukraine, at same time waste, especially droppings litter. Intensive uncontrolled use fresh as organic fertilizer agricultural plants has economic ecological disadvantages. Therefore, there is need store (ferment) certain period (up 20 months) order it safely crop Bacteria play important role course enzymatic processes during its storage. It scientific interest determine bacteria with litter (cereal straw) stored different times cold season. content microorganisms was determined chickens. Samples were taken January air temperature 1.3 °C under conditions experimental farm Bila Tserkva National Agrarian University from 2 days after unloading houses, which 4 9 months barns. CFU Bacillus spp., Staphylococcus Streptococcus spp. Escherichia coli indicator KMAFAnM unloaded houses 3.5x108. Until 4th month storage droppings, increased. For storage, index decreases by 58.7 compared obtained composting. A group represented following species: subtilis (dominant), mesentericus, megaterium mycoides. Colonies sown periods dry, wrinkled surface. They colorless light velvety color. edges colony this bacterium wavy. lowest rate found houses. that largest. In months, 10 lower months. mainly aureus saprophyticus. 4.6x107. largest greater than beginning 28.8 53.1 relative Research detection had negative result regardless droppings. not detected.

Microbiological Safety of Chicken Litter or Chicken Litter-Based Organic Fertilizers: A Review
Chicken litter or chicken litter-based organic fertilizers are usually recycled into the soil to improve the structure and fertility of agricultural land. As an important source of nutrients for crop production, chicken litter may also contain a variety of human pathogens that can threaten humans who consume the contaminated food or water. Composting can inactivate pathogens while creating a so...
