The modernized domestic complex of LLC "Belgrankorm – Veliky Novgorod" is engaged in the production of embryos, eggs, meat, its processing and freezing and facilitates productivity of chickens, safety of a livestock, body weight gain, achieves the reduction of rearing terms by 5 days and the decrease of feed expenses on 1 kg of production.The duration of the incubation period of eggs in the cabinets of the incubation shop is 18 days. During the following incubation phase (from 18th to 21st days) toxic substances, gases and decay products accumulate in the cabinets. They also get into the body of embryos and hatched chickens, as well as maintenance personnel. Modernized poultry farm facilities enable embryos to be transported by mobile method for three days (from 18th to 21st day) directly to poultry houses (buildings) for hatching of chickens and their subsequent rearing. This can significantly reduce the amount of toxic substances, gases and decay products, energy and financial costs and improve environmental and biological safety. On the 18th or 19th day, egg embryos were exposed to ozonation for 5 min by the "Rios–20" apparatus with a capacity of 20 g/m3. With the current technology, hatching of chickens directly in the housing (poultry house) occurs on the 21st day, when they jump out of their lofty perches in special conveyor belts, quickly find their "working" places, identify their drinking bowls (nipple), feeders and litter (with grain). Broiler chickens of cross "Hubbard" were reared.
