PREPARATION OF FEED 217 



Feed Troughs. The front of the feed troughs consists of 

 one piece 4-inch by 4-inch (two pieces 2-inch by 4-inch). Two 

 pieces 2-inch by 2-inch will be better for young pigs. From this 

 front are placed 2-inch by 2-inch divisions, 12 inches . apart, 

 running up to a 1-inch by 3-inch piece laid along the sides as 

 shown. For general use a trough width of not more than 9 

 inches is recommended. 



Eoof. The roof is laid on 1-inch by 3-inch battens, and 

 covered with ready roofing. The hinging arrangement shown 

 is simple, and prevents leaking at the peak. A prop should be 

 supplied to hold up the door, or roof when filling. It is best 

 to continue the overhang of the cover so that the drip may not 

 affect the troughs in wet weather. 



Side. The width is shown in the drawing. The length will 

 depend on the number and size of the pigs to be fed. A 6-foot 

 feeder (12 feet of trough) is a commonly used size, and will feed 

 up to twenty-five young pigs. 



Cost. Built of new lumber the cost should not exceed $10. 

 Use dressed lumber preferably, and give the exterior a coat 

 of paint 



Provided the requirements enumerated are met, changes in 

 details may be suggested by the ingenuity of the builder.
