Abstract
The main purpose of the present study was to determine the proper size of tower silo for experiments, from the standpoint of pH, organic acid formation, digestibility and storage lass. 1) First growth of orchard grass and Ladino clover mixture (84% of moisture content) was ensiled in each of 0.5, 2.0 and 15 tons tower silo under the same treatments without preserative. Herbage was cropped by mower bar type's forage harvester in early July 1966. 2) Results are summarized in the following Table 1. 3) In the silage in larger silo was ensiled higher dry matter per cubic meter than in that in smaller one. 4) The silage ensiled in larger silo showed lower pH, and butyric acid and higher lactic acid content and dry matter digestibility than that in smaller one. 5) Also dry matte losses were higher in larger silo than in smaller one. 6) As a result, it is suggested that the 2 tons capacity silo is suitable for observation of silage qualities, storage loss and digestibility from the experimantal point of view.
