9. Breed directory. Let each pupil make a report on the names of swine breeders in the locality and the breeds raised. This may be made into a breed directory for the community.
10. Making a concrete hog wallow.[4] A hog perspires but little during hot weather and is forced to seek a cool mud wallow if nothing else is provided. This has resulted in the impression that the hog is a dirty animal.
A concrete hog wallow provided with a drain will enable the hog raiser to give his hogs a cool, clean refuge from the heat. If a small amount of crude oil is poured on the surface of the water, it will serve to rid the animals of lice and keep the skin in good condition. If possible, the wallow should be located near the water supply, either a tank or spring. The following sectional view of a wallow is taken from the Cement News published by the Universal Portland Cement Co.
1. Sectional View of a Concrete Wallow
It is recommended that the pool be made rectangular with rounded corners. It should not have a depth of more than 18 inches. The size should be determined by the number of pigs kept. A concrete floor 4 feet wide laid around the pool will prevent rooting and the carrying of mud into the wallow.
2. Trough for Young Pigs
11. Wooden troughs for swine. In figures 2 and 3 are shown two types of wooden troughs that are used extensively by swine raisers. The one shown in figure 2 is designed for use in feeding young pigs. As shown in the drawing it is shallow and is constructed with a flat bottom and wide end pieces. The shallowness makes it easy for the young pigs to get at the feed, and the wide ends make it difficult for the pigs to overturn it. The cross pieces prevent the hogs from lying in the trough. The drawing gives all necessary dimensions. Make out a bill of material and a bill of stock, cut the pieces, and assemble them.
