title: Utilization of choline from crude soybean lecithin by chicks. 1. Growth and prevention of perosis.
abstract: Data obtained with growing chicks fed a semi-purified diet indicate that choline from crude soybean lecithin is as well utilized as synthetic choline chloride, on the basis of growth, relative liver weight and prevention of perosis. Extrapolation of the results on growth and perosis prevention, obtained between 1 and 3 weeks of age, to performance on practical-type diets yields choline requirements for broiler-type chicks ranging from 800 to 1000 mg./kg. diet (as choline chloride). The requirement seems to decrease with age.
