silage necessitates warm quarters Lot IV was fed in an open shed as 

 compared with Lot III on a similar ration in the basement of a warm 

 barn. Table III shows that during the winter of 1909-10, which was 

 much colder than the average of recent years, the silage-fed cattle in 

 the open shed made much more rapid gains than those in the barn. 

 It should be remembered in this connection that the shed gave ample 

 protection from wind and rain and was well bedded at all times. The 

 gains in all lots were satisfactory for light cattle fed for five months 

 to a high marketable finish.

 A Comparison Between Bulky and Concentrated Rations. 



The summary shows that Lot I, fed a heavy grain ration, made 

 more rapid gains than Lot II, fed a medium grain ration, during the 

 entire feeding period of 140 days. In order to make the same pro- 

 portion of digestible nutrients in the rations of each lot the amount of 

 cottonseed meal was limited to two pounds, per head, daily, in Lot I 

 and 2.25 pounds in Lot II. It will be noted that the total amount of 

 air-dry matter consumed was greater in Lot I. The amount of air-dry 

 matter required to produce one hundred pounds gain is determined by 

 the character of the feeds used, the method of feeding and the con- 

 dition of the cattle at the beginning and at the close of the feeding
