This experiment was conducted to enhance nutritional value of whole crop corn silage and increase mixture levels of broiler excreta by adding of corn meal. Treatments were included non mixture(control), adding 10, 20, 30% of broiler excreta and adding 10, 20, 30% of broiler excreta and corn meal as a fresh matter basis, respectively. One liter laboratory silos were prepared. The characteristics of fermentation and micro-organisms during the silage process were assessed. The results obtained are summarized as follows: 1. The crude fiber, NDF and ADF contents were high in whole crop corn(P(O.Ol), crude protein and crude ash contents were high in the broiler excreta(P<0.05), and NFE content was high in corn meal (P< 0.05). 2. Crude protein content of silage was increased(I'<O.Ol) with increasing levels of broiler excreta and corn meal, while contents of crude fiber(l'<0.01) and ADF(P<0.05) were decreased. 3. Total $NH_3$-N contents of silage were markedly increased with increasing levels of broiler excreta and corn meal, and was the highest in the 30% broiler excreta treatment(P<O.Ol). 4. The pH of the silage with mixture of broiler excreta and corn meal was higher than that of the control( P<0.05). Lactic acid content was increased in the silage with mixture of broiler excreta and corn meal, especially lactic acid fermentation was very favorable in the silage with mixture of corn $meal$ <0.05), and Flieg's value gains "very good" by showing organic acids. 5. Numbers of total bacteria and lactobacilli were $10^5$ to $10^7$ and $10^5$ to $10^6$ , respectively, and were similar in all treatment. Colliform was all but annihilated in the treatment with mixture of broiler excreta and corn rneal.orn rneal.
