Object of study: improving assessment methods at forming highly cross stud poultry egg Isa Brown. Objective: improved methods of assessment during the formation of highly stud poultry egg cross Isa Brown. Methods: General zootechnical methods, methods of scientific knowledge (observation, comparison, measurement, experimentation); methods of empirical level (analysis, synthesis, simulation); special techniques (forecasting, data preprocessing, measuring relationships). Theoretical and practical results, in theoretical terms - expanded range of knowledge on methods of forecasting egg productivity of individual biological characteristics of birds of hematological parameters, morphological characteristics eggs. In practical - use methods of distribution of birds on balance group enables to increase egg production by 3.7 ... 4.1 pc. the average laying hen, egg weight by 4.7 ... 8.4 g and 3.4 provide ... 26.2 thousand. UAH additional revenue per 1000 goal. productive herd. Novelty first time proved the impact of differentiation on the basis of replacement chicks "live weight" and "length shank" to enhance the egg and experimentally proved the possibility of improving existing evaluation methods and highly directional selection bird egg cross when forming herds. Developed further provisions on the need for a differentiated approach to the layers of cell battery for maintaining certain bird which equilibrium groups, classes M and M M M + - upper tiers, poultry M0M0 class - upper and middle, classes M + H + and M + M - lower. The degree of implementation, the results are used in PJSC "Chornobaivske" Belozersky district, Kherson region when forming herds of highly cross. Scope - poultry.
