The amount of feed your horse/Pony requires:
This recommendation is intended as a guide only and represents the quantity of feed required to provide a balanced diet according to horse/ pony’s ideal bodyweight. If your horse/pony is prone to any clinical conditions or maintains weight easily on less than the recommendation of feed please contact the Care-Line for more advice.
Total Daily Feed Intake
The following table can be used as a guide to estimating your horse/ pony’s total daily feed requirements but regular body condition scoring is a useful and more practical way of assessing whether they may need to increase or decrease their daily intake.
Total Daily Appetite (% bodyweight/ day) Overweight 1.5 Maintenance
Pregnant mares (1-8 months)
2 Medium work 2.25 Underweight
Pregnant mares (9-11 months)
Forage should be the foundation of every horse/ pony’s diet and fed ad-lib (as much as they will eat) where ever possible. For good doers, total forage intake should not be restricted to less than 1.5% of bodyweight (DM) per day. Visit the FAQ’s for tips on how to feed forage.
Height (hh) Approximate weight (kg) Minimum daily forage intake (kg/ day DM including grazing) 10-11.3 150-200 2.5-3 12-12.3 200-250 3-4 13-13.3 300-350 4.5-5 14-14.3 400-450 6-7 15-15.3 500-550 7.5-8
Compound feeds (mixes and cubes) are formulated to provide a balanced diet when fed at the recommended ration in conjunction with suitable forage.
The following table can be used a guide to for calculating the level of feed required to provide a balanced diet for horses at rest or in light work.
Height (hh) Approximate weight (kg) Recommended ration of compound feed (kg/ day) 12-12.3 200-250 1-1.5 13-13.3 300-350 2 14-14.3 400-450 2.5-3 15-15.3 500-550 3-3.5 16-16.3 600-650 3.5-4
Balancer Feeding Rates
With the exception of SPILLERS GRO ‘N WIN®, all SPILLERS® Balancers are designed to be fed at a rate of 100g per 100kg of per day if fed alongside forage alone.
Height (hh) Approximate weight (kg) SPILLERS® Balancer fed alongside forage only (g/ day) SPILLERS® Balancer fed alongside compound feed (g/ day)* 12-12.3 200-250 200 100 13-13.3 300-350 300 200 14-14.3 400-450 400 300 15-15.3 500-550 500 400 16-16.3 600-650 600 500
*As a guide we recommend feeding half the balancer if feeding half of the recommend ration of compound feed.

- Weighing your Feed
Horses are fed by weight not volume. As the density of feeds and forage varies considerably, we would always recommend them regularly. However the following table can be used as a guide.
Approximate Weight Approximate Weight Stubbs scoop (2.5l) Section of hay (small rectangular bale) 2kg Bale of hay (small rectangular bale) 20kg Small bale of haylage 200kg Large bale of haylage 25kg Cubes 1.8-2.3 Mix 1.5 SPILLERS® Fibre 500-600g Chopped Fibre (such as alfalfa/ alfalfa & straw without pellets) 300-400g Molassed chaff 250g
