What has the State Agricultural Experiment Station at Hoorn contributed to research into the feeding value of roughage.

Work on the digestibility of fresh and dried grass, hay and silage, carried out at Hoorn (mainly in the period 1930-50) is reviewed. An account is given of attempts to formulate relationships between the contents of crude fibre and digestible organic matter in hay and grass, and between the contents of crude protein and digestible crude protein in grass (fresh and dried), hay and silage.-W.J.B.
