Dosage chart: senior horses 15+

Short version: see the overview

From the age of 15, a horse's need for vitamins and minerals increases, because absorption declines and the teeth wear down. That's why senior horses have their own chart with higher figures. The chart covers both Every Day Happy and Peak Performance.

If your horse is 15 or older, use the figures on this page, not the chart for 0-14 years. Find the workload, find the weight, read off the grams per day.

If you don't have a mineral analysis of your forage, feed at Ekstra level. All doses are by dry weight.

Why senior horses need more

1. Reduced absorption and utilisation

With age, the gut becomes less efficient at absorbing nutrients. This means the horse gets less benefit from vitamins and minerals, even with the same feed intake.

2. Dental wear and chewing problems

Senior horses often chew less effectively because of worn teeth, tooth loss or sharp enamel points. This makes it harder to get the most out of the forage, which is otherwise an important source of minerals. The result is a lower intake of micronutrients from the feed.

Good planning makes everyday feeding easier

We recommend that you get to know what matters most for your horse's needs, i.e. the key factors, and how we calculate your horse's workload. The Normal, Ekstra and Maximum doses are just as important for planning. The definitions of light, moderate and hard work are in the guide to feeding amounts.

If your horse is 14 or younger, use the dosage chart for 0-14 years instead.

Don't have a mineral analysis of your forage?

Then we recommend following the Ekstra level in the dosage chart. It's the best way to make sure your horse gets enough of the important trace minerals, even if you don't know exactly what's in the forage.

If, on the other hand, you do have an analysis and the mineral levels are roughly as below, you can safely use the normal dose of, for example, Every Day Happy, Peak Performance or Supreme Minerals:

Mineral in the forage Level that allows a Normal dose
Copper 4-5 mg/kg
Zinc 20-22 mg/kg
Manganese 40-50 mg/kg
Iron 100-110 mg/kg
Calcium approx. 4 g/kg dry matter
Phosphorus 2.0-3.0 g/kg dry matter

As horses absorb only a small proportion of the iron in forage, typically 10-15%, and as many analyses show low values, we often recommend the Ekstra to Maximum level if your forage is low, particularly in iron.

Remember salt every day

Horses have no salt reserves and need salt daily along with the daily dose of Every Day Happy or Peak Performance.

  • Maintenance: 10 g salt per 100 kg of horse per day. For a 500 kg horse, that's 50 g
  • For moderate work, give 15-17 g of salt and for demanding work 22-27 g per 100 kg on top of Every Day Happy or Peak Performance (with Supreme Minerals, 18-20 g and 25-30 g in total). Heat, pregnancy and lactation also increase the requirement.
  • A salt lick alone is not enough. Add loose salt to the feed, and build up from half a teaspoon over 14 days

Stallions

Stallions need a daily dose at least 10% higher than the chart states to be fully covered. We recommend feeding stallions at Ekstra level relative to their workload.

Pregnant and lactating mares and their foals

When the mare is pregnant

Up to the 8th month, she is fed according to how much work she is in. From the 9th to the 11th month, she is fed as a horse in moderate work.

After the mare has foaled

For the first 3 months, she is fed as a horse in hard work, because she needs to produce milk for the foal. After that, she is fed as a horse in moderate work until the foal is weaned and no longer suckling.

If the mare is both pregnant and has a suckling foal

Then she is fed as a horse in hard work for the entire period she is producing milk. Once the foal is weaned, follow the recommendations for the pregnant mare again.

Feeding foals

Foals from approx. 2 to 5 months need approx. 1 gram of feed per day per kg of the foal's body weight. Foals from 6 months and youngstock are fed based on their expected adult weight, at the level for horses in light work or normal turnout.
