Dactylis glomerata is a species of flowering plant in the grass family Poaceae, commonly known as cock's-foot, orchard grass, or cat grass (due to its popularity for use with domestic cats). It is a cool-season perennial C3 bunchgrass native throughout most of Europe, temperate Asia, and northern Africa.

Forage is a plant material eaten by grazing livestock. Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage.
