(4) Steers receiving larger amounts of nitrogen stored larger amounts. 



(5) The amount of nitrogen consumed had no effect upon the percent- 

 age of protein in the increase in live weight. 



(6) Differences in the ration and in the age of the steers had no effect 

 upon the percentage of protein in the increase of live weight. 



(7) An average of the results for eight steers for 37 weeks shows that 

 14.71 per cent of the increase in live weight was protein. 



(8) The amount of protein and energy consumed had no effect upon 

 the percentage of the protein retained. 



(9) It is indicated that a smaller percentage of the protein is retained 

 as the age of the animal increases. 



(10) An average of the eight steers for 37 weeks shows that 22.37 

 per cent of the protein digested was stored in the body.
