The cattle used in the test were two and three-year old cattle, 

 a description of which will be found on page 7. 



In each of two years' trials four lots of 10 steers each were 

 fed the following rations : 



Lot i. Shelled corn, cottonseed meal 2.5 pounds per 1000 

 pounds live weight daily, clover hay, (morning), corn silage, 

 (evening). 



Lot 2. Shelled corn, cottonseed meal 2.5 pounds per 1000 

 pounds live weight daily, clover hay. 



Lot 5. Shelled corn, cottonseed meal 1.25 pounds per 1000 

 pounds live weight daily, clover hay, (morning), corn silage, 

 (evening). 



Lot 6. Shelled corn, cottonseed meal 1.25 pounds per 1000 

 pounds live weight daily, clover hay, morning, corn silage, evening. 



The only difference between the rations of Lots i and 5, and 

 between those of Lots 2 and 6 is in the amount of cottonseed meal 

 fed. A comparison of Lots i and 5 shows the relative value of 

 adding 2.5 and 1.25 pounds respectively of cottonseed meal daily 

 per 1000 pounds live weight to a ration of shelled corn, clover hay, 

 and corn silage. A similar comparison is shown in Lots 2 and 6 

 except that the basal ration consists of shelled corn and clover hay 

 without corn silage. The proportion of cottonseed meal to the live 

 weights of the cattle was adjusted every 10 days according to the 

 weights of the cattle. 



i. INFLUENCE "OF DIFFERENT PROPORTIONS OF COTTONSEED MEAL 

 IN A RATION OF SHELLED CORN, CLOVER HAY, AND CORN SILAGE 



Since the first effect of a ration is usually shown in the appe- 

 tites of the cattle, the average amount of the feed consumed daily 

 per steer by 30 day periods is presented in Table VI.
