Ackerson, C.W., Ham, W.E. and Mussehl, F.E. (1940). The utilization of food elements by growing chicks. IX. The nitrogen of urea (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No.120)
1. The effect of replacing one-third of the concentrate of a ration for growing chicks with a mixture of starch and urea that contained an amount of nitrogen equal to that contained in the concentrate withdrawn from the ration was studied with two lots of chicks. 2. All chicks of both lots consumed equal amounts of nitrogen during the experiment. 3. Conclusions were based on increases in body weight and content of nitrogen, calcium and phosphorus at slaughter.
