THE EARTH'S BOUNTY 



the summer and preventing the silo from rot- 

 ting. 



In the double or lined silos freezing may be 

 avoided by checking the ventilation, and by 

 keeping the door in use carefully closed in 

 severe weather. If the top layer of silage 

 freezes, some of the warm silage may be mixed 

 with the frozen silage an hour or two before 

 feeding time, and all the silage will then be 

 found in good condition when fed out. A 

 layer of straw may be kept as a cover over the 

 silage. This will prevent it from freezing, 

 and is easily cleared off when silage is to be 

 taken out. 



If frozen silage is not fed out directly after 

 thawed it will spoil, and soon become unfit to 

 be used for cattle food. Thawed silage will 

 spoil much sooner than ordinary silage that 

 has not been frozen and thawed out. There is 

 no evidence that silage which has been frozen 

 and slowly thawed out, is less palatable or 

 nutritious than silage of the same kind which 

 has been kept free from frost.
