It is usually found in endophyte-infected species of grass like Tall fescue [1] or Perennial Ryegrass. [2] It is toxic to cattle feeding on infected grass, probably because it acts as a vasoconstrictor .
Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [2]
It is also known as timothy-grass, meadow cat's-tail or common cat's tail. [3] It is a member of the genus Phleum , consisting of about 15 species of annual and perennial grasses.

Another term adopted by the industry is grass-finished (also, 100% grass-fed [7]), for which cattle are said to spend 100% of their lives on grass pasture. The Agricultural Marketing Service of the United States Department of Agriculture previously had a regulated standard for certification as "Grass Fed" meat, but withdrew the standard in 2016.
