1. The optimum level of each ingredient for the date-palm leaf silage (DPLS) was determined by chemical composition and digestibility. The result indicate that the under fifty percent of NaOH treated date-palm leaf is the optimum amount.
2. The quality of DPLS ensiled at high temperature (50℃) and fluctuation (15℃-50℃) is leas than that of low temperature (30℃).
3. Major Lactic acid producing microorganism at high temperature is identified as Lactobacillus acidophilus.
4. From the result of short term feeding trial, 40L20M40W DPLS fed group showed better result than 45L25M30W DPLS. TDN, DM digestibility and DM intake of 40L20M40W and 45L25M30W were 52, 53%, 995 g/day and 41, 46%, 557 g/day, respectively.
5. The equipment is consisted of cutting machine, hammer crusher, cyclone, NaOH treating section, and mixing unit. The equipment was transferred to Saudi Arabia, set up and operated. The equipment is in satisfactory operational condition.
6. For the long term feeding trial, over one hundred tons of DPLS was already prepared by the use of the equipment and the long term feeding experimental is being carried out in Saudi Arabia (King Faisal University).
