This study was conducted to determine the effect of feeding grass silage or pea-wheat bi-crop forages differing in maturity at harvest and pea to wheat ratio on voluntary feed intake (VFI), in vivo digestibility, and nitrogen (N) retention in sheep. Two bi-crops drilled at pea to wheat ratios of 25:75 (low pea; LP) or 75:25 (high pea; HP) on a dry matter (DM) basis were grown on each half of 6.5 and 3.5 ha fields and harvested after either 13 (cut 1; C1) or 15 (cut 2; C2) weeks of growth. The 4 resulting forages were ensiled in separate 40 t clamp silos and evaluated against a perennial ryegrass (PRG) silage, as a control, in an in vivo digestibility trial.
