good quality with the exception of the cottonseed meal, which showed 

 by direct analysis that it contained only 33.62 percent protein. The 

 chemical composition of the feeds used was determined by the Depart- 

 ment of Agricultural Chemistry as given in the following table: 



PERCENTAGE COMPOSITION 



Carbohydrates 



Feed Water 



Cottonseed 6.50 



Cottonseed meal 6.14 



Cottonseed hulls 7.99 



Corn silage 71.21 



Alfalfa hay Z.7 



The complete rations fed to the cattle were as follows: Lot I, 

 corn silage, alfalfa hay, and cottonseed meal; Lot H, corn silage, 

 alfalfa hay, and whole cotton seed; Lot III, corn silage, alfalfa, and 

 crushed cotton seed ; Lot IV, corn silage and cottonseed meal ; Lot V, 

 same as Lot I ; Lot VI, cotton seed hulls and cottonseed meal. 

 The comparisons are : 



L Cottonseed meal with whole cotton seed. Lots I and V 

 with 11. 



2. Corn silage with cottonseed hulls. Lots IV and VI. 



3. Whole cotton seed with crushed cotton seed, Lots II 



and III. 



The cattle were divided into five lots of eight head each, care 

 being taken to make each lot as nearly uniform as possible in quality, 

 weight, and condition, and one lot of ten head in which were the smaller, 

 more timid animals culled from the entire number. The feed lots 

 in which the cattle were fed were alike in construction, each meas- 

 uring 48x60 feet with a feed manger 3 feet wide and Z6 feet long. 

 No shed or covering was needed as there were no heavy rains, and 

 the temperature during the test varied from 28° F. to 94° F. 



The animals had free access to salt and water at all times. 



Prior to the experiment proper, all the cattle were fed a liberal 

 ration of alfalfa hay and silage for a period of ten days in order to 

 get the animals to eating well before beginning the actual test.
