Feed requirements of horses
On this page
Correct nutrition is important for both health and performance of your horse. The nutritional needs of horses depend on:
- age
- growth
- activity
- health
- environment.
Feed cost calculator
A simple way to determine feed costs is by using the
Feed cost calculator on the DPI NSW website.
By creating a daily feed budget, you can calculate how much feed you will need for your horses, each day, week and month. Then you can estimate how much feed you will need, as well as an approximate cost to feed your horses until the next spring.
To create a feed budget specific to the weight and condition of your horse, there are 6 steps you need to take:
Step 1
Estimate the weight and condition score of each horse (refer to
Condition scoring and weight estimation of horses or use a weight tape).
Step 2
Separate your horses into categories, refer columns 1 and 2 of Table 1:
Table 1. Daily energy and protein requirements for different categories of horses (from Nash, 1999)
Type of Horse | Mature weight (kg) | Daily live weight gain (kg/day) | Digestible energy (MJ DE) | Crude protein (g) |

Step 3
Determine the nutritional needs of each horse using Table 1.
Step 4
Ascertain the nutritive values of common feeds using Table 2:
Table 2. Average nutritive value of common feeds (adapted from Nash, 1999, Kohnke, 1999 and Huntington et al. 2004).

Step 5
Determine how much feed each horse can consume daily.
You can then calculate if certain feeds can be consumed in sufficient quantities to provide the required nutrition.
Horses are able to consume about 1.5 to 2% of their body weight in dry feed (feed that is 90% dry matter) each day. As a rule of thumb, allow 1.5 to 2 kg of feed per 100 kg of the horse's body weight.
However, it is safer to use 1.7% of body weight (or 1.7 kg per 100 kg of body weight) to calculate a feed budget. This is to ensure that the horse can consume the full amount of feed each day.
To calculate how much feed each horse can consume daily, use the following example formula:
weight of horse (kg) x percent of bodyweight / 100
For example, for a 500 kg horse with an intake limit of 1.7 % of its body weight:
500 x 1.7 / 100 = 8.5 kg feed that can be safely consumed each day
Dice al final
Hint 1: Addition of a vitamin and mineral supplement is recommended to ensure a balanced diet.
Por lo que solo el heno (forraje) no es recomendable. Aunque no haga mucho ejercicio físico. Si no come hortalizas/frutas que le aporten todo lo necesario habrá que hacerlo con pienso.
