Tannins and saponins
Pea forage may contain condensed tannins, depending on the variety. This would apply to whole crop forage of coloured-flowered varieties, including mature seeds (Rondahl, 2004). Pea straw has also been found to contain saponins (Zaza et al., 2009).
Moulds
Pea forage may be subject to moulding, before harvest or during storage. Pea straw should be stored at a minimum of 87% DM to prevent moulding. If moulding occurs, the straw should not be given to animals (Leclerc, 2003).
Defoliant
When defoliant treatments are applied before grain harvesting, a waiting period of 5 days is recommended before harvesting the straw (Leclerc, 2003).
