Grazing
Timing and type of grazing will influence species selection and vice versa. Livestock type will also be significant due to grazing and browsing habits. Sheep will do well on whereas cattle…. Although many species work well for both cattle, sheep, breeding and growing animals.
​
Cutting
Where leys are grown in arable systems, the aim may be to cut and export the forage. As species composition may vary throughout the season, feeding value and yield will also vary. Where the intention is to both graze and cut, consider grazing early in the season to encourage establishment and tillering by mob grazing where an area is defoliated within ane or two days and then left to regenerate.
Grazing may be possible after cutting but should allow sufficient time for root reserves to build up before defoliating again.

Green manure
Once the sward has finished it’s most productive period, the remaining biomass can be mown and removed, mulched or finely cut and incorporated as a green manure, providing a source of organic matter for following crops.
