Comparative Development Indicators ofPartridge Chicks (Alectoris Chukar) During Cell Breeding

The paper presents experimental data on the negative impact of negative biotic and abiotic factors on the development of stone partridges (Alectoris chukar) in vivarium conditions, the identification of optimal terms and conditions for growing young partridges in cages in vivarium conditions and in aviaries.In the first 30 days after the transfer of partridges to aviaries, the average daily gain of both cell and aviary was almost the same. From day 31 to day 41, the gain in weight of the partridge mass contained in the vivarium incages was 5.8–12.0 g lower than that found in the enclosures.All partridges from 31 to 41 days had the same rate of weight gain, but from 31 to 41 days, the gain in partridges in the vivarium increased compared to the weight gain in aviary. Thus, the influence of negative conditions on the development of young partridges of domestic fauna was revealed.It was experimentally established that the life span of partridges for the 13 and 25-day growing periods reached 96% and 97%, respectively. At the same time, the life span of partridges where, along with heating, was also irradiation of the room with ultraviolet and infrared radiation for a 13-day period of cultivation, reached 100% of the value.
