Despite the difficult conditions of martial law, Ukrainian poultry farming remains one of the most stable branches of the agricultural sector and is gradually restoring production capacity, including enterprises engaged in the production of incubation eggs.
In Ukrainian poultry farms, crosses of chickens imported from abroad are used to produce chicken eggs. The reproductive potential of poultry is one of the determining factors for the effective development of the poultry industry, as it directly affects the volume of egg production, the restoration of the livestock and the economic efficiency of farms.
The reproductive ability of poultry is determined by a set of indicators that characterize its potential for reproduction and obtaining healthy young. The main evaluation criteria include egg production, egg fertilization, hatching of chicks and their survival. The purpose of the work was to investigate the reproductive ability of chickens of the parent flock of different ages of the cross "Novogen Brown" in the conditions of LLC "Slovyany".
As a result of the conducted research, it was found that the egg production indicators of the “Novogen Brown” cross-breed hens in the conditions of LLC “Slovyany” were lower than the standard level. At the same time, for 420 days of life, 218 eggs were obtained per initial layer, and for 510 days – 282.2 pcs. For 72 weeks of life (504 days), the potential egg production according to the standards should reach 298.6 eggs per initial layer. The level of egg fertilization varied within significant limits – from 62.00±0.63 to 93.80±0.32% and depended on the age of the parent stock. The hatchability of young birds was also characterized by significant fluctuations: the highest level was 88.86±0.42% (age of chickens 314 days), while the lowest was 62.00±0.63% (age of chickens 502 days). The survival of chicks during rearing during the first 10 days after hatching did not depend on the age of the parent flock and was 97.4–98.0%.
