Breeders of edible eggs, using various crosses of chickens, try to reduce the cost of production. In this regard, interests of hen crosses that produce egg products with low feed costs and low cost. One of these egg crosses of hens is “Lohmann brown light”. At the same time, domestic poultry farms successfully use the “Lohmann Braun classic”cross poultry. The aim of the study was to evaluate the egg productivity indicators of laying hens of the industrial herd of crosses “Lohmann brown classic”and” Lohmann brown light”. The study was carried out in the conditions of LLC Poultry Farm “Varaksino” of the Udmurt Republic. For the research, 2 groups of hens were formed, consisting of 6 batches each. As a result, hens of the studied crosses were characterized by approximately the same viability and level of livestock preservation – 94.1 – 94.3 %. Crosses of hens “Lohmann brown classic” and “Lohmann brown light” had minor differences in quantitative and qualitative indicators of egg production. Thus, egg production for the initial and average laying hens in the groups was at the level of 348.2 – 350.5 and 353 – 355.2 eggs, respectively. The amount of egg mass from the cross “Lohmann brown classic” hens was 22.9 kg, and from the cross “Lohmann brown light” - 22.6 kg. On an equal background of feeding, there were no differences in the cost of feed for the production of 10 eggs (1.29 – 1.31 kg) and 1 kg of egg mass (2.03 – 2.05 kg) in the studied hen crosses. |
