“…Hill (1948) reported that various samples of soybean oil meals affected the growth response obtained in chicks with supplements of whey, fish meal and fish solubles. It was, therefore, decided to conduct an experiment in which a purified soybean protein, sodium proteinate, 2 was used as a substitute for soybean oil meal.…”

“…Vitamin supplements were added as shown at levels sufficient to meet or exceed recognized requirements without dependence on the crude feedstuffs in the diet. Fishmeal, dried whey, and dried brewers' yeast were employed to meet the needs of chicks for certain unidentified vitamins required for rapid early growth (Hill, 1948;Combs 1950;Heuser and Norris, Menge, Combs, Hsu and Shorb, 1952).…”

T HE energy requirement of growing chicks has been studied in two widely different ways. One method is illustrated by the studies of Mitchell, Card and Hamilton (1931) who estimated the net energy requirements for maintenance and growth from the determination of basal metabolic rate and changes in body composition. Data of this kind have been of limited usefulness because of the lack until relatively recently of net energy values for poultry feedstuffs.The other method was used by Robertson, Miller and Heuser (1948) and Panda and Combs (1950). They studied the relationship between productive (net) energy of the ration and early growth rate to determine the minimum energy level per unit weight of the ration necessary to promote the maximum rate of growth. Both of these groups concluded that the minimum productive energy level required for maximum early growth rate was approximately 800-850 Calories per pound of ration on the basis of the productive energy values of poultry feedstuffs as reported by Fraps (1946). The experiments to be described in this paper were undertaken to obtain further information on the minimum dietary energy level necessary for maximum early growth rate of chicks.
