II. FATTENING BEEF CALVES ON COTTONSEED MEAL, 

 COTTONSEED HULLS, CORN CHOP, AND CORN SILAGE. 



PLAN OF WORK. 



This test was conducted during the winter of 1912—13. The feed- 

 ing began November 29, 1912, and closed, as far as the corn silage 

 was concerned, March 3, 1913. The supply of corn silage was ex- 

 hausted on March 3, but the calves were not ready for sale, so all 

 were placed in one lot (they had formerly been divided into three 

 lots for the sake of certain feed comparisons) and continued on a 

 ration of cottonseed meal, corn chop, cottonseed hulls, and mixed 

 alfalfa hay until April 29, 1913. when they were sold. 



As these calves were of the same breeding, had been raised in the 

 same way and from the same cows, and were fed in the same lots 

 as those fully reported upon in Part I of this bulletin, it is not neces- 

 sary to enter into a discussion of the objects of the work, of the kind 

 of calves used, of the general plan of the work, of the method of 

 feeding and handling, and of the shelter and lots. 



THE RATIONS EMPLOYED. 



Practically the only material way in which this test varied from 

 the previous one was in the feeds used. In this test corn silage was 

 introduced into the rations of two of the lots and was fed from 

 November 29, 1912, to March 3, 1913, when the supply was exhausted. 

 Each lot of 16 calves was fed the following feeds: 

 • Lot 1. Cottonseed meal ; cottonseed hulls. 



Lot 2. Cottonseed meal, two-thirds ; corn chop, one-third ; cottonseed hulls ; 

 corn silage. 



Lot 3. Cottonseed meal ; cottonseed hulls ; corn silage. 



On March 3, 1913, they were all thrown together as one lot and 

 continued to April 29, 1913, on the following: 



Lot 4. Cottonseed meal ; corn chop ; cottonseed hulls ; mixed hay. 



Corn silage was the only new feed introduced. In the financial 

 statements it is valued at $3 a ton, and the other feeds are valued 

 as on page 7. 



The cottonseed meal this year was fresh and bright, analyzing 

 from 7.5 to 7.7 per cent ammonia. The cottonseed hulls were only 

 fair in quality. The corn chop (made by grinding shelled corn) 

 was of excellent quality. The corn from which the chop was madi 

 was grown upon the farm and was fresh and hard. The corn silage, 

 however, was poor in quality owing to the fact that the fodder ha< 

 become too dry before it was made into silage.
