Wintering yearling cattle, H. J. Waters {Missouri 8fa. Bui. 75, pp. 53). — 

 Various coarse fodders with and without grain were compared for wintering 

 cattle. The tests with coarse fodders extended over 4 years and included 14 

 lots of 4 to 6 steers each. 



In the first test timothy hay and whole-corn stover were compared and an 

 average gain of 29 pounds per head was noted on the hay and a loss of 2 lbs. on 

 the stover. 



Shredded corn stover and siloed corn stover were included as well as whole 

 corn stover and timothy hay in the second test, which covered 02 days. On the 

 siloed stover and the timothy hay there were gains of 10.8 and 32.2 lbs., re- 

 si)ectively, and on the whole stover and the shredded stover there were losses 

 of 11.8 and 15.6 lbs. 



In a test- covering 74 days, which was practically a duplicate of the above 

 except that clover hay and shredded corn stover 1 : 1 were also studied, there 

 was an average loss on shredded corn stover of 7.7 lbs. per head and gains on 

 the other feeds ranging from 13.8 lbs. on whole corn stover to 77.2 lbs. on siloed 

 corn stover. Good gains, namely, 58.4 lbs. per head, were also noted on the 

 clover hay and corn stover. 



In the fourth test whole-corn stover and clover hay 1 : 1 were again fed in 

 comparison with timothy hay and whole stover. On the clover-hay ration there 

 was an average daily gain per head of 0.09 lb. and on the hay and stover 

 rations losses of 0,11 and 0.76 lb., respectively.
