The three-means get across chickens was basically bred inter se. Choices was accomplished to have egg production, viability and you will fleshing.
From inside the earliest stage away from options inbreeding was used. An average inbreeding coefficient in the traces are just about 20% and the genetic resemblance factor was forty-five%. The newest multiplication away from outlines try centered on category mating of dicks that have chose half-sibs or sibs.
By the 1967 the fresh new reproduction group, which included the lines A beneficial, B, C and you will D, designated over 7 000 lead. Regarding top pens the fresh eggs yield achieved 220 and you may champion layers brought 260-280 egg a year.

Egg-layer the color is actually light brownish. Fertility away from eggs is located at ninety-five%; hatchability is actually 85%. Emergency price of one’s more youthful as well as people is 95 and you will 90% respectively. Annual production averages 215-228 eggs consider 56-58 g. Offer consumption for each ten eggs is actually 1.86-2.00 kg.

Years within intimate maturity is 170 months. An average annual creation are 180 egg regarding 58 g; egg shell was white. Virility away from eggs try 95% and you may hatchability 90%. Endurance price of the young stock are 95% and of adults ninety%.
