Effect of day and night rhythms on the ratio of different chicken eggs components at the start of lay
New data on the ratio of eggs’ different components of chicken grown in new day-night rhythms is given in the article. At the start of lay, the average mass of yolk of experimental birds was 0.84 % higher, the mass of albumen decreased by 0.93 %. The proportion of egg shell increased by 0.1 % in experimental eggs. Direct positive correlation between total egg mass and yolk and albumen masses has been established for experimental birds.
