A Preliminary Report on the Shrinkage Occurring in Sealed and Unsealed Silos

R. R. Snapp and H. W. Bean

University of Illinois

Abstract

Careful records have been kept for seventeen years of the material stored in and removed from the animal husbandry silos at the University of Illinois. During this period nearly 6800 tons of silage have been made, or an average of 400 tons a year. The present equipment consists of six 12' by 40' uncovered silos erected in 1917 and two 14' by 36' covered silos built in 1931. Each is a monolithic concrete structure with a continuous 22'' doorway extending from a point 2 feet above the ground to the top. Doors made of 1'' by 6'' tongue and groove lumber are put in place as the silos are filled and a strip of 36'' felt roofing paper is fitted snugly on the inside of the doors to exclude the air as much as possible. Although a little spoiled silage is encountered along the doorway, it seldom is damaged to the extent that it cannot be fed. All of the silos have concrete bottoms with no provision for drainage. Consequently, no seepage of excess moisture can occur.
