3. Trough for Mature Hogs
Figure 3 shows a V-shaped trough for older hogs. Like the one shown for young pigs, it is wide at the ends and is provided with cross pieces. The drawing gives all necessary dimensions. Make out bills of material and stock, and construct.
12. Hurdles for use in stock judging. A hurdle as described in this exercise is a panel of boards made as shown in figure 4. Hurdles are portable and are useful when sorting hogs into groups or when scoring and judging them. Three or four hurdles fastened together at the ends make a very good temporary pen.
4. Hurdle
The materials required are four pieces 1 by 4 inches by 12 feet, one piece 2 by 4 inches by 8 feet, and 2 pounds of eightpenny common nails. To build the panel, cut the pieces as shown in the drawing. Lay the four pieces of 2 by 4 inches on the floor, spacing them 4 feet apart, nail the bottom board, space 2 inches and nail the second board, space 3 inches and nail the third board, and nail the fourth board on the top.
13. Making a collection of feeds. Secure a supply of small bottles and make and label a collection of samples of feeds suitable for pigs.
14. Weighing pigs with steelyards.[5] In the pig project it is recommended that the pig or pigs be weighed each week. Where stock or platform scales are at hand the weighing can be performed easily, but, unfortunately, some boys do not have scales of any kind which they can use for this purpose. In project work boys do not generally feel that they can afford to purchase platform scales, but since the weighing is a very important part of the work, some means should be provided, and steelyards are suggested for the purpose. These are not expensive, costing about $3.00, and with proper arrangement can be used very satisfactorily. For weighing feed they can usually be suspended from joists in granaries, but for weighing the pig it will probably be necessary to construct a horse from which to suspend them. A crate also will be needed for holding the pig while being weighed. The material required for these articles is not expensive and both can be constructed by the boys in the club or class.
Suggestions For Making Horse and Crate[6]
Material. Any ordinary lumber having proper dimensions can be used. If new lumber is purchased, yellow pine will serve the purpose satisfactorily, costing 2½c or 3c per lumber foot. The length suggested for the horse is 8 feet, though this can be reduced by placing the steelyards at right angles to the length of the horse in place of in the same direction, as suggested by the cut. The height should be 7 feet to provide space for fastening the crate to the steelyards. The legs should be beveled at upper ends before nailing to rail and should be spread at bottom so as to measure 3½ feet. Stock required for constructing horse is as follows: One piece 2″×6″×8′ if made eight feet long; two pieces 2″×6″×14′; or 2″×4″×14′ for legs; two pieces 1″×6″×10′ for braces.
