The three-way cross birds was in fact bred inter se. Alternatives are carried out getting egg manufacturing, stability and you will fleshing.
Inside the very first phase regarding possibilities inbreeding was used. The common inbreeding coefficient on the lines is only about 20% plus the hereditary resemblance foundation are forty five%. The fresh new multiplication away from contours try centered on group mating away from cocks which have selected 50 % of-sibs or sibs.
From the 1967 the fresh breeding head, which included this new traces A good, B, C and you may D, designated more than 7 one hundred thousand direct. On the best pens new eggs yield achieved 220 and you may champion layers lead 260-280 eggs per year.

Age in the sexual readiness try 170 days. The average annual manufacturing is actually 180 egg from 58 g; egg-shell is actually white. Virility regarding egg is actually 95% and you will hatchability ninety%. Success rates of the young inventory is actually 95% and of adults 90%.
