In comparing the growth from Jan. 4th to Feb. 23d on hay and 

 grain with that made from Feb. 24th to Mar. 27th, on hay, ensi- 

 lage and grain, we find a more rapid gain during the latter period. 

 We also find that in the second period the animals each ate about 

 a pound a day more of digestible matter than in the first period, 

 which is sufficient to account for at least a part of the increased 

 growth, as the ratio of food to live weight was somewhat larger 

 in this period. The ratio of digestible food to growth was practi- 

 cally the same in the two cases. 



In the case of the later periods, Apr. 29th to May 29th, and 

 May 30th to June 27th, in passicg from a ration of hay, ensilage 

 and grain to one of hayand grain, there was a small decrease in the 

 rate of gain, while the amount of digestible material consumed 

 per day remained unchanged. 



In regard to this experiment comparing hay and ensilage in 

 feeding for growth, we are warranted in saying : 



(1.) A pound of digestible matter from the corn ensilage 

 produced somewhat more growth than a pound of digestible 

 matter from Timothy hay. The difference was small, however, 

 amounting in the case of the last two periods, where the more 

 accurate comparison is possible, to an -increased growth of 

 only X5 pounds of live weight for each ton of ensilage fed.
