The table below gives an approximate guide to forage and concentrate feed ratios by weight for horses according to workload.

Workload Hay Concentrate feed
Resting 100% 0%
Light Work 75% 25%
Medium Work 60% 40%
Hard Work 40% 60%
Fast Work 30% 70%

Therefore as an example, a horse weighing 500 kilograms and consuming 2% of its body weight in food (10 Kg) per day would require the following approximate weights of forage and concentrate feed per day.

Workload Hay Concentrate feed
Resting 10 Kg 0 Kg
Light Work 7.5 Kg 2.5 Kg
Medium Work 6.0 Kg 4.0 Kg
Hard Work 4.0 Kg 6.0 Kg
Fast Work 3.0 Kg 7.0 Kg
