This is exactly why we have such a lot of natural foliage and herbs for the boys to browse on ❤️
Horses Are Not Grazing Animals… They’re Specialist Browsers
This might be one of the biggest misconceptions in horse management.
We often describe horses as grazing animals, standing with their heads down eating grass all day. While they certainly graze, their natural feeding behaviour is actually far more complex than that.
Wild and feral horses spend huge portions of their day browsing. They don’t just eat grass. They seek out hedgerows, shrubs, leaves, bark, herbs, flowers, seed heads, weeds and even certain tree species. They constantly move across the landscape, selecting different plants to meet different nutritional and behavioural needs.
Think about a horse turned into a field with a healthy hedge line. How often do you see them reaching through the hedge for hawthorn, blackberry, rosehips or fresh leaves rather than standing in the middle eating grass?
That isn’t boredom. It’s natural behaviour.
The irony is that many of our modern horse paddocks bear very little resemblance to the environment horses evolved to live in. Vast areas of single-species grass provide plenty of calories but very little variety.
Much of the UK’s improved pasture has been heavily selected for agricultural productivity, particularly for cattle production. Ryegrass has become a dominant species because it produces high yields and supports milk and meat production extremely efficiently. The problem is that what works brilliantly for a dairy cow doesn’t necessarily work brilliantly for a horse.
Many improved ryegrass pastures contain significantly higher levels of readily available sugars than the diverse meadow systems horses would naturally encounter. Yet we continue to place animals designed to browse a wide variety of plants onto fields dominated by a single, energy-dense grass species.
Then we scratch our heads and wonder why we are seeing increasing numbers of horses struggling with obesity, insulin dysregulation, laminitis and other metabolic disorders.
Of course, metabolic disease is multifactorial. Genetics, exercise, management and overall diet all play a role. But it does raise an interesting question:
Are we feeding horses in a way that matches millions of years of evolution?
Browsing provides:
🌿 Nutritional diversity
🌿 Natural enrichment
🌿 Increased movement
🌿 Mental stimulation
🌿 Opportunities for self-selection of plant material
🌿 Access to a wide range of plant compounds not found in monoculture grass systems
Perhaps the question shouldn’t be “How much grass does my horse need?”
Perhaps it should be “How much variety does my horse need?”
Because when given the choice, many horses don’t behave like lawnmowers.
They behave exactly as nature intended — as specialist browsers.
