Adley (Coix lacryma-jobi L.) foliage was harvested three times a year at the stage of ear emergence and was used for the preparation of wilted silage and pressed cake silage. Pressed cake was prepared by crushing, pressing and dejuicing the foliage. In every harvest, pressed cake silage was low in crude protein, ether extract and crude ash contents and high in crude fiber and nitrogen free extract content compared with wilted silage. Both the wilted and the pressed cake silages from the third harvest were good in chemical quality, while wilted silages from the first and the second harvests were in poor quality. But the poor quality was improved by processing the materials to pressed cake at the time of ensiling. The silages from the three harvests were fed to goats with the same amount of dry matter from wheat bran in two 4 x 4 Latin square trials. In every harvest, DCP content of wilted silage was a little higher than that of pressed cake silage, though the differences were very small. Between the three harvests, the first one was superior to the second and the third harvests in the digestibility of crude fiber. But no systematic and significant differences were found in TDN. As the results, DCP and TDN contents of every mixed ration were similar and were about 10 and 70%, respectively, in dry matter basis. No any abnormalities were found in the ruminal VFA and ammonia concentrations. Plasma cholesterol concentrations of goats were not affected by the dietary treatments
