The best was option for rate of growth as much as sixty times of many years: live lbs out of cockerels improved regarding 624 so you can 1074 grams, regarding pullets from 557 to 928 g. Whenever reared towards large-protein rations (23.4% rough protein), mediocre real time lbs away from ninety-day-dated cockerels hit 2052 which out-of hens 1545 grams.
