Timothy Grass is commonly grown for cattle feed and, in particular, as hay for horses. It is relatively high in fibre, especially when cut late. It is considered part of the standard mix for grass hay and provides quality nutrition for horses. Timothy is a staple food for domestic pet rabbits, guinea pigs,chinchillas, and degus, often making up the bulk of their diet. If the stalk is cut from the tubers before evidence of maturity appears, with nutritin arrested, the proper growth will cease. An effort is made to repair the injury by sending out small, lateral tubers, as shown here.
