Calculate your horse’s feed ration
What requirements need to be taken into consideration
in a horse’s feed ration?
How to evaluate your horse’s requirement?
You have to know:
- Your horse’s mean weight: see the page "Estimate your horse’s weight"
- Your horse’s level of work (rest, light, moderate or intense work)
Horses on artificial bedding (shavings, flax, etc.):
No straw in the stable for the horses to feed on (less chewing activity; risk of cellulose deficiency, etc.)
- Provide larger quantities of hay: 7 to 8 kg per day
- Choose a combined feed with a safe formula in terms of protein/cellulose balance (S 100, S 200, S 250)
How to evaluate nutritional content?
Nutritional content in the basic ration excluding combined feeds:
- Type of basic ration (straw, hay, cereals, grass)
- Characteristics (hay quality, grass composition (seasonal effect)
- Exact quantities ingested
Nutritional content to be sourced from combined feeds in order to supplement the basic ration:
=> Please Refer to the technical data sheet for the feed stating its nutritional characteristics and nutrient content.
Typical ration calculation:
Requirements as per the INRA (the French National Institute for Agricultural Research):
Horses weighing 500 kg, undergoing moderate work: 1 to 2 hours a day, walking, trotting, cantering, require:
- 7.5 EFU
- 480 g of EDNM
- 10 to 12 kg of DM
Nutritional content of a theoretical basic ration for a given day:
- 5 kg of hay: 2.2 EFU
- 4.2 kg of DM
- 3 to 4 kg of straw: 0.8 EFU
- 2.6 to 3.5 kg of DM
- Total EFU provided in the basic forage ration: 3.0 EFU
- Total dry matter content: 7.2 kg
Nutritional content required from the feed in 2 or 3 rations:
Provision of daily EFU requirements: 7.5 EFU – 3.0 EFU = 4.5 EFU
With S 200: 4.5 EFU (to be provided) / 0.75 EFU (provided in 1 kg of feed) = 6 kg/day, i.e. 9.2 litres (5.3 kg of dry matter provided by the feed)
Provision of dry matter requirements: 7.2 kg DM + 5.3 kg DM = 12.5 kg of DM
A horse on wheat straw consumes approximately 3 to 4 kg/day, i.e. 0.88 EFU.
One segment of meadow hay = 1.5 to 2 kg, i.e. 0.67 to 0.90 EFU
Density and equivalent values:
- Whole cereals 1 litre = approx. 550 g for oats
- 1 litre = approx. 600 g for barley
- Rolled cereals 1 litre = approx. 300 g
- Pelleted feeds 1 litre = approx. 650 g
- Flaked feeds 1 litre = approx. 450 g
- Mash 1 litre = approx. 380 g
CAUTION: Remember to distinguish between litres and kilos and please weigh so as to avoid any risk of mistakes!
1 kilo of feed, irrespective of type = 88 % dry matter
