AGRICULTURAL EXPERIMENT STATION. 77 



and the other, 1:9.7. One pair ate 1884 pounds of digestible pro- 

 tein in the same time the other pair ate 1070 pounds. 



(2) One steer of each pair was slaughtered and analyzed at the 

 end oi seventeen months feeding, the remaining steers being fed for 

 ten months longer, when they were killed and analyzed. The chem- 

 ical analysis included the entire bodies, excepting the skin and the 

 contents of the stomach and intestines. 



(3) At the end of fifteen months feeding, the pair of steers fed 

 on the ration richer in protein had gained 221 pounds of live weight 

 more than the pair fed the ration less rich in protein. The later 

 growth with two steers showed a difference in favor of the ration 

 less rich in protein. 



(4) The relative weights of organs and parts of the body was 

 practically the same with the steers of the same age, independently 

 of the ration. 



(5) The kind of growth caused by the two rations, viz: the pro- 

 portions of water, protein, fat and ash, was not materially different 

 with the steers of the same size. 



This is true whether we consider the entire bodies, the dressed 

 carcasses or the edible portions of the carcasses. 



With steers fed for the same time, the composition of the entire 

 bodies, the proportion and composition of the carcasses, and the pro- 

 portions and composition of the edible parts were practically alike. 



(6) The older pair of steers, viz: those fed for ten months longer 

 time, contained a smaller proportion of water and a larger propor- 

 tion of fat than the younger animals. 



(7) The older animals furnished five pounds per hundred more of 

 water-free edible material than the younger animals. This is equiv- 

 alent to a difference of twelve pounds of fresh, edible meat.
