At harvest LT1 and LT2 yielded 8.7 and 7.5 tonnes DM/ha respectively. In treatment LT1 where the lupins and triticale were
sown separately, 0.73 of the material consisted of lupins with the remaining 0.27 as weeds. The triticale was predominantly
triticale with little or no weeds. In treatment LT2 where the lupins and triticale were sown together, 0.84 of the material
consisted of triticale, 0.13 of lupins and 0.03 of weeds.
The grass silage (A and B) offered in the study was of high quality as indicated by the CP concentration (122 and 160 g/kg
DM), low ammonia-N (52 and 67 g/kg total N) and high D-value (726 and 706 g/kg) (Table 2). The maize silage was of
moderate quality as indicated by D-value of 673 g/kg and ME of 11.2 MJ/kg DM. Starch concentration was 193 g/kg DM. The
legume/cereal silages were poor quality as evidenced by the high concentrations of ammonia-N (182 and 173 g/kg total N),
high pH (5.0 and 4.7), low lactic acid (9 g/kg DM) and low ME (10.4 and 9.0 MJ/kg DM) for LT1 and LT2 respectively
