Abstract: The results of studies concerning the development of methods of early assessment and selection of ostriches to increase egg production are submitted. Found that, in general, over 14 weeks, blacked-neck ostrich egg production was 32.8 ± 1,27 eggs on average per layer, and blue-necked – 28.4 ± 0,32 eggs. Thus, the black-necked ostrich egg production was higher by 4.4 eggs. It was found a great correlation between the number of eggs laid by ostriches during the first four weeks of laying season and for the whole season (r=0.68-0.71). This is the reason for development of evaluation methodology and selection of ostriches in the case of selection for laying capacity increase. The using of a new technique provides a shorter interval between the generation ostriches for 1 year and the growth rate of breeding to increase their egg production by 0.2 eggs per year. In the event of a system is provided by the new method of accelerating the breeding process to increase the ostrich egg production by 0.2 eggs per year, or one egg in a single generation.
