The Value of Choline Additions to a Corn and Soybean Oil Meal Chick Ration Containing Distillers’ Dried Solubles ,

The Use of Crystalline Riboflavin and of Supplementary Choline in Starting and Growing Rations for Turkeys

“…Among the many reports which testify to the growth-promoting function of choline in turkey rations are those of Jukes (1940aJukes ( , 1940bJukes ( and 1941a. The similar function in chicks has been reported by Jukes (1941b and1941c), Hegsted et al (1941), Bethke (1941 and, Jukes and Welch (1942) and Marvel et al (1944 and1945). The recent work of Boucher (1946) suggested that the addition of one pound of choline per ton of the practical ration used enhanced growth to fourteen weeks.…”

Soybean Oil Meal in Poultry Rations

“…Recent work by Berry et al (1943) and Marvel et al (1945aMarvel et al ( ), (1945bMarvel et al ( ), (1945c indicates that soybean oil meal is adequate in protein quality, but deficient in some of the vitamins supplied by animal products. Bird and Groschke (1942) reported that the efficiency of feed utilization was greater when combinations of soybean oil meal, corn gluten meal, and some animal protein were fed, than when corn gluten meal was omitted.…”

The Effect of Selection of Chicks Upon Variability in Growth Data

“…The possibility of a biased conclusion being drawn from small samples has been pointed out by Schroeder and Lawrence (1932) and more recently by Hill, Slinger and Motzok (1944). One method of selecting chicks to be used for experimental work is to start with a relatively large number in each group and then at a given age, reduce the size of the groups by using "the median chick plus a predetermined number on either side of the median (Marvel et al, 1945). The conclusions then are drawn on these selected groups.…”
