“Hogging-down” of corn is a practical and efficient method of gathering the crop and feeding the hogs.
Farmers who have tried it are almost unanimously agreed that the method is economical and successful. The most enthusiastic “hogging-down” men are those who have followed the method longest. The animal husbandry section of the Iowa Agricultural Experiment Station has in practical tests convincingly justified this faith of the practical men.
