dc.description.abstract This study measured the chemical composition, aerobic stability, feed intake, in vivo digestibility, nitrogen (N) balance and rumen degradability of spring-sown, whole crop peas (WCP) and intercropped pea–wheat bi-crop silages harvested at three stages of maturity. The WCP was harvested at the pod swell growth stage. The bi-crops were harvested after 14, 17 and 18 weeks of drilling, when the peas and wheat were respectively at the pod swell and early milk (cut 1), dry seed and early dough (cut 2) and early pod senescence and dough (cut 3) growth stages. The forages were conserved in 600 kg bales without additive treatment for 90 days and then analyzed for chemical composition, aerobic stability, rumen degradation, in vivo digestibility and N balance. The voluntary feed intake, in vivo digestibility and N balance of the bi-crops was measured using 6, 9 month-old, Suffolk cross wethers that were housed in separate metabolism crates. The WCP forage was similarly evaluated in a separate experiment. In situ degradation was measured in three ruminally-fistulated cows fed a perennial ryegrass silage diet without concentrate. The level of peas in the forages at harvest ranged from 90 to 170 g/kg dry matter (DM). The pH, DM and starch contents of the bi-crop silages increased (P en
