| Grass Hay. |
| Introduction |
| Historically, hay was the most common
method of conserving crass. It aims to reduce the
moisture content of the green crop to a level low enough
to inhibit the action of plant and microbial enzymes. Hay
can be made from traditional pastures or meadows, or a
residual hay from a grass seed crop. |
| Origin |
| Around the world. |
| Nutritional Information |
| The quality of conserved grass is
obviously dependent on the quality of the grass used. For
adequate conservation, the moisture content of grass must
be reduced to approximately 15%. The plants inevitably
lose some nutrients from the action of plant and
microbial enzymes, chemical Oxidation, leaching and
mechanical damage. Quicker drying, therefore, reduces the
loss of nutrients from the fresh forage. Nutritional
quality of the hay is obviously dependent on the quality
of the fresh forage (see Grass Fresh), and the losses
listed above plot any residual respiration losses in
storage |
| Colour/Texture |
| Green and fibrous |
| Palatability |
| Good if well preserved. |
| Limits on Usage |
| The nutritive value varies dramatically so
appropriate analysis should be undertaken. Badly made or
stored crops can be dusty and or mouldy. Check for
poisonous weeds if origin of bales is unknown. |

| Handling/Storage |
| Drying can be speeded up by conditioners.
However excessive mechanical damage can promote further
damage. |
