The best are selection for rate of growth as much as sixty days of ages: real time weight regarding cockerels enhanced regarding 624 to 1074 g, that pullets out-of 557 to help you 928 g. Whenever reared into higher-healthy protein rations (23.4% crude proteins), mediocre live lbs regarding ninety-day-dated cockerels achieved 2052 and this regarding hens 1545 g.
The amount of Kuchino Jubilee birds increased off 9300 inside the 1974 so you’re able to 53 one hundred thousand in 1980.
