Digestion Experiments With W ethers. 31 



The per cent of protein in the second cutting is less than 

 in the first cutting, but the digestion coefficient is greater, which 

 tends to balance the actual amount of protein available to the 

 animal. In all Wyoming forage grown at high altitudes, we 

 have found the ether extract abnormally low and the percent- 

 age of crude fiber and protein in general high. This seems to 

 hold true for alfalfa, as may be noted by comparing with the 

 analysis given by Jenkins and Winton, Bulletin II, U. S. De- 

 partment of Agriculture.
