This study was carried out to enhance the nutritional value of whole crop corn silage and the utilization of animal waste as a ruminant feedstuffs. Whole crop corn were ensiled with cage layer excreta and concentrate. Treatments included whole crop corn silage (control), 10% cage layer excreta and concentrate-corn silage (CES lo), 20% cage layer excreta and 10% concentrate-corn silage (CES 20) and 30% cage layer excreta and 10% concentrate-corn silage (CES 30). The characteristics of silage fermentation was evaluated. Digestibility and palatability of the silage were observed through the feeding trial with four male Corridale sheep. The results obtained are summarized as follows: 1. Cage layer excreta-corn silage showed higher contents of crude protein and crude ash than control silage, while crude fibre content was significantlv lower than that of control silage (P(.01). 2. Total nitrogen and ammonia nitrogen content of the cage layer excreta-corn silage was significantly (P< .01) higher than that of control, but CES 10 silage was good in quality. 3. Lactic acid content of CES 10 silage was the highest, but that of CES 20 and CES 30 silage was lower than that of control. CES 20 and CES 30 silage was lower lactic acid content and higher pH than control. Therefore Flieg's score was wrose than that of control silage. 4. The numbers of total bacteria and lactic fermentation bacteria were estimated lo7-10' and 10"1OH, respectively, and there were no significant differences among treatments. Coliform numbers were not detected with CES 10 silage while were detected lo3 per gram in CES 30 silage. 5. Digestibility of crude protein, crude fibre and ADF was improved significantly in the animals fed the cage layer excreta-corn silage compared with animals fed the control silage. DCP and TDN were the highest in the CES 10 silage. 6. The intake of daily nitrogen and dry matter per metabolic body weight was the highest in animals fed the CES 10 silage.lage.
