SUMMARY 



1. The development of the range country changed the center of production 

 of feeding cattle from the corn belt to the west. In view of the present agri- 

 cultural development of the range renewed interest attaches to the breeding cow 

 and her offspring and methods for feeding them in the corn belt. Page 325. 



2. The object of this experiment was to compare feeds readily available on 

 Illinois farms for maintaining beef breeding cows during the winter season. 



Page 326. 



3. Silage, shock corn, and corn stover, respectively, proved to be economical 

 feeds for the maintenance of cows when fed in connection with clover hay and 

 oat straw. Pages 328 and 329. 



4. The average daily gain per cow in lot i was 1.07 pounds. The average 

 daily ration per cow consisted of corn silage, 16.64 pounds ; clover hay 3.5 

 pounds ; and oat straw, 9.56 pounds. Pages 329 and 330. 



5. The average daily gain per cow in lot 2 was .758 of a pound. The aver- 

 age daily ration per cow was shock corn, 8.7 pounds ; clover hay, 3.5 pounds; 

 and oat straw, 10.83 pounds. Pages 329 and 330. 



6. The average daily gain per cow in lot 3 was .41 of a pound. The average 

 daily ration per cow in this lot during the time the cows were confined to stover 

 and oat stray, was corn stover, 21.67 pounds; oat straw, 5.15 pounds; and when 

 clover hay was used, stover, 10.28 pounds; clover hay, 1.56 pounds; and oat 

 straw, 8.19 pounds. Pages 329 and 330. 



7. Under the conditions of this experiment, silage produced 41 percent 

 greater gain in live weight than an equal acreage of shock corn. Page 329. 



8. The cows in this test would not eat as much shredded stover as un- 

 shredded, and clearly preferred the latter. Page 331. 



9. The yield of crops used in this test was 57.9 bushels corn and two tons 

 stover per acre; and for crops purchased, viz., clover hay and oat straw, yields 

 of 1^4 and one ton respectively were assumed. Page 331. 



10. On the above basis approximately one acre of land is sufficient to pro- 

 duce the crops necessary to support a breeding cow 140 days in winter, and this 

 acreage should produce a considerable amount of grain in addition to that nec- 

 essary for the maintenance of one cow. Page 332. 



11. The product of one-third acre -of land is sufficient to maintain a cow 140 

 days in winter, if we regard the surplus srrain produced as offsetting an acreage 

 proportionate to its market value. Page 333-
