Fifty-two-day-old guinea grass (Panicum maximum var. maximum cv. Gatton) which received 150 kg N per hectare and IO-month-old leucaena (Leucaena leucocephala (Lam.) De Wit.) were used. There were five treatments viz., guinea grass (T I)' leucaena (T 1)' guinea grass-leucaena(T J, guinea grass-leucaena with starch (T,) and guinea grass-leucaena with formic acid (T ,). Both guinea grass and leucaena were mixed in a grass:legume ratio of 7:3 in T"T. and T,. Samples were stuffed into laboratory silo (1.4-1.5 kg sample) and stored for 42 days. Samples were takenat and after ensiling and analysed for total nitrogen,volatile basic nitrogen as per cent of total N, pH, lactic acid, acetic acid, butyric acid, neutral detergent fibre (NDF), acid detergent fibre(ADF), celhilose, acid detergent ligninADL) and in vitro dry matter digestibility (IVDMD). Guinea grass had significantly lower (PO.OI) nitrogencontent but higher content of fibre compared to leucaena. The IVDMD values (50%) were similar (P0.05) in both guinea grass and leucaena. Combining guinea grass with leucaena significantly (P0.05) raised the nitrogen content of the mixture but slightly reduced the cell wallcomponents. It also raised the IVDMD value (54 per cent)though not significantly. Addition of starch reduced the nitrogen content and the cell wall consistency but increased the IVDMD value (56 per cent). These changes were significant (P0.05). Guinea grass silage had a significantly (PO.05) lower pH and volatile basic acid (VAN) than leucaena. Guinea grass with leucaena starch had the lowest pH but was not significantly different from T1, T, and T,.The lactic acid content of T. was significantly higher (P0.05) than the o1hers. T, has the lowest VBN.
