Reproduction work at the newest populations out-of Russian White birds was directed in order to increasing alive weight, eggs lbs and you can egg development.
EGG-Chicken Breeds MOSCOW (Moskovskaya)

The step 3-method get across chickens have been bred inter se. Selection was accomplished getting egg manufacturing, stability and you will fleshing.
For the earliest stage away from choice inbreeding was applied. The common inbreeding coefficient throughout the outlines is just about 20% and genetic resemblance grounds are forty five%. The fresh multiplication out of traces are based on class mating out of cocks having selected half-sibs or sibs.
Because of the 1967 brand new breeding head, including the fresh lines An effective, B, C and you may D, designated over seven one hundred thousand direct. On top pencils the newest eggs yield hit 220 and champion levels introduced 260-280 egg annually.

Ages at sexual maturity is 170 days. The common annual production are 180 eggs out of 58 g; egg-shell is white. Virility regarding egg was 95% and you will hatchability ninety%. Survival speed of your own young stock was 95% as well as people 90%.
