Safety of replacing young poultry of egg direction in the growing conditions on different technological equipment

An experiment to study the safety of replacing young birds of the Loman LSL cross-country egg-laying bird was carried out in the Pyshminskaya Poultry Farm Closed Joint-Stock Company in the Tyumen Region in the period from 2018 to 2019 on the equipment of Techna of domestic and Big Dachmen equipment of imported production. The content of chickens in the amount of 45,000 heads in each group was studied until they reached 120 days of age. The experiment involved early maturing chickens of the four-line cross Lohman LSL of the German company Lohmann Tierzuht. The birds of this cross are used in the creation and breeding of new and highly productive lines and crosses in the Russian Federation. Objectives: to identify the best option for keeping young poultry on the basis of a comparative analysis of technological equipment and determining the efficiency of growing chickens on the equipment Techna and Big Dutchman. A comparative analysis of the microclimate parameters on different equipment was carried out according to such indicators as temperature, relative air humidity, air movement and ammonia content in the air. The effectiveness of different methods of keeping poultry was determined by the percentage of young animals leaving in three batches, ready for transfer to the industrial herd shop. It has been established that on German equipment the air speed exceeds the standard values by 160 %, the temperature by 11 %, and the relative humidity is 18 % higher than the standard values. On Techna equipment, the microclimate parameters are as close as possible to the normative indicators. The content of ammonia in the amount of 0.06 % was found on the German equipment, while the content of ammonia was not detected on the domestic equipment. The safety of poultry on the Techna equipment was higher than on the Big Dutchman equipment, by 0.21 %.
