152 BEEF PRODUCTION 



cattle are to be accommodated, viz., the smaller feeders 

 can be moved when it becomes muddy about the feeder 

 and where occasion requires they can, if built strong 

 enough, be moved from one field to another. The 

 height of the floor of the feed trough should be from 

 twenty-four to thirty inches, depending upon the age 

 and size of the cattle fed. 



By referring to the sketch (Figure 17 and 17A), it 

 will be seen that the outside dimensions of the box for 

 storage of feed are 12 feet 2 inches long, 5 feet 6 inches 

 high, and 4 feet 4 inches broad. This box or storage 

 bin has a capacity of approximately 180 bushels. The 

 detailed drawing, or sketch, will show the construction 

 of the hopper bottom, feed troughs, roof, door, etc. 

 The drawing does not correctly illustrate that the hop- 

 per bottom of the storage bin lacks four inches of com- 

 ing out flush with the wall of the bin and that the open- 

 ing left for feed to feed out of the hopper into feed troughs 

 is two and one-half inches wide. This width of the 

 opening and pitch of the bottom of bin should vary with 

 the kind of feed to be used. That is, if broken corn is 

 used a much wider opening will be required; if shelled 

 corn, a narrower one. The opening left in this case was 

 for feeding meal. Six-inch flooring was used for the 

 sides and floor. A shingle roof is of course unneces- 

 sary, but was used in this case, the shingles being laid 

 four inches to the weather. 



BILL OF MATERIAL NECESSARY 



The following is a bill of materials necessary to build 

 the feeder, as illustrated: 



Seventeen pieces 2x4, 16 feet; six pieces 2x6, 16 feet 

 one piece 2x6, 8 feet; twenty-four pieces 1x4, 16 feet 

 two pieces 6x6, 12 feet; thirty pieces 1x6, 12 feet 

 one piece 6 x 8, 18 feet; 1700 shingles. 



Nails, paint, and labor, together with the materials 

 itemized, make this feeder cost from $30 to $35, depend- 

 ing upon the grade and price of materials used. In
