SILOS AND SILAGE.

SILO DOORS. , 



The silo doors should be so arranged that the minimum amount of silage will 

 have to be disturbed when they are taken out. The continuous door has proven 

 to be more convenient than the non-continuous types. In stave silos the doors are 

 very often made of the same material as the silo itself. Sections of the staves are 

 cleated together to form the doors. The advantage of the continuous door suggested 

 the use of the staves without the cleats to fill the continuous opening. In the case 

 of many of the silos constructed by the Department of Agriculture during the past 

 season sections of the tongued and grooved staves were placed one on top of the 

 other as shown in Fig. 10. The advantage is very evident when the silage is taken 

 out. One 6-inch section can be taken out at a time. If rough staves are used, the 

 same system can be followed. In this case, however, it is advisable to use a roll of 

 building-paper. By attaching it to the bottom of the door-space it can be unrolled 

 against the inside of the door as the silo is being filled, thus ensuring that the door 

 is practically air-tight.

EOOF. 



Although not absolutely essential, a roof on a silo has many advantages, 

 especially for winter feeding. During stormy or severe weather the snow is kept 

 out and the silage is prevented from freezing. Fig. 11 suggests an attractive and
