Selection of Japanese quail for the high egg production under hypodynamy

A line of Japanese quail resistant to hypodynamy (14 days of exposure during the egg-laying period) was selected from the parental population, using the criterion of best egg-laying, and bred to the fourth generation. The level of egg-laying increased in each successive filial generation, reaching i...

Description
Summary:A line of Japanese quail resistant to hypodynamy (14 days of exposure during the egg-laying period) was selected from the parental population, using the criterion of best egg-laying, and bred to the fourth generation. The level of egg-laying increased in each successive filial generation, reaching in the fourth generation 52 percent of the control on the 14th day of exposure, compared with the 16 percent in the parental population. The selection also had a positive effect on the adaptability to hypodynamy with respect to increased weight and rate of growth of quail chick, as well as to diminished fearfulness. The study was conducted in the framework of research on adaptation to the specific conditions of space flight (weightlessness and limited space).
