Grass or Alfalfa hay ?
By Dallas Mount, University of Wyoming assistant
extension educator, Platte County
Many horse owners spend a lot of time and money
to find the right hay for their horse; however, many of the
less expensive, more available hays may work fine.
Alfalfa vs. Grass:
There is a common misconception that only high-
quality grass hay will work as a horse?s main source of
roughage. There is no reason to think alfalfa hay is harmful
to horses when fed properly. Most alfalfa hay contains
larger concentrations of both protein and energy than
typical grass hay; therefore, alfalfa hay may be a better
buy than grass hay when the two types are the same price.
Because alfalfa hay is more nutrient dense, care should be
taken when feeding alfalfa. Alfalfa hay can cause horses to
founder and develop laminitis due to the excess nutrients
provided by the high-quality hay if too much is fed. If
switching from grass hay to alfalfa, less alfalfa is generally
required to provide the same nutrients present in the grass
hay. The best way to evaluate the amount of hay that
should be fed is to monitor the horse?s body condition.
In General:
To avoid digestive and respiratory problems, always
visually inspect hay for mold, dust, or other foreign material.
When changing feeds, adapt a horse to the change slowly to
avoid digestive upset, such as colic. The more gradual the
dietary change, the less chance for digestive upset.
Feed sampling, laboratory analysis, and ration evaluation
are the best steps to ensure a horse is receiving the
required nutrients. Check with a local Cooperative Extension
Service office for help in sampling and analyzing feed
or to formulate a horse ration.
