<p>Increased activity such as training, exercise or racing increases the energy requirement. The requirement can be defined within the program as a continuous function which calculates the requirement as a multiple of the maintenance energy requirement. The program provides in addition four pre-defined levels of work:</p>
<table style="width: 460px; height: 174px;" border="1">
<tbody style="text-align: left;">
<tr style="text-align: left;">
<td style="text-align: left;"><strong>Work intensity</strong></td>
<td style="text-align: center;"><strong>Requirement</strong></td>
</tr>
<tr style="text-align: left;">
<td style="text-align: left;">Light work</td>
<td style="text-align: center;">Energy (MJ) = 1.25 * Maintenance requirement</td>
</tr>
<tr style="text-align: left;">
<td style="text-align: left;">Moderate work</td>
<td style="text-align: center;">Energy (MJ) = 1.50 * Maintenance requirement</td>
</tr>
<tr style="text-align: left;">
<td style="text-align: left;">Hard work</td>
<td style="text-align: center;">Energy (MJ) = 1.75 * Maintenance requirement</td>
</tr>
<tr style="text-align: left;">
<td style="text-align: left;">Intense work</td>
<td style="text-align: center;">Energy (MJ) = 2.00 * Maintenance requirement</td>
</tr>

<p><br />It may be difficult to judge the level of work. We recommend that you estimate a level of work calculated backwards from the ration that the horse is receiving currently. The program will help you with this process. Later, adjust the feeding if the horse is losing or gaining weight.</p>
