We all know horses love grass – it's their natural diet, after all. But have you ever stopped to think about what kind of grass they're munching on? In the UK, it's so common to see paddocks dominated by just a few rye-grass species. While it looks lush and green, for our equine friends, a monoculture of grass can be about as exciting (and healthy!) as eating plain toast every day.
Here in the UK, we're lucky to have a rich tapestry of native grasses, and embracing that variety in our paddocks can make a world of difference to our horses' well-being, especially when it comes to their gut and hooves.
Common UK Grasses You Might Spot (and why variety is key!):
While Ryegrass often dominates, here are some other common UK grasses you might encounter and why having a mix is beneficial:
-
Perennial Ryegrass (Lolium perenne): Very common in agricultural pastures due to its fast growth and high yield. It can be high in rapidly digestible carbohydrates (sugars), which can be a concern for laminitic or sensitive horses.
-
Timothy (Phleum pratense): A popular hay grass, Timothy is coarser and typically lower in sugar than Ryegrass. It's a good source of fibre and well-liked by horses.
-
Fescues (Festuca species - e.g., Meadow Fescue, Tall Fescue, Red Fescue): These are hardy, persistent grasses that tolerate a range of conditions. They tend to be more fibrous and generally lower in sugar than Ryegrass, making them good for gut health.
-
Cocksfoot (Dactylis glomerata): A robust, deep-rooted grass that's drought-tolerant and provides good bulk. It can be a bit coarse but offers valuable fibre.
-
Bents (Agrostis species - e.g., Common Bent, Creeping Bent): Often found in older pastures and less intensively managed areas. They tend to be finer and contribute to a dense sward.
-
Meadow Grasses (Poa species - e.g., Rough Meadow-grass, Smooth Meadow-grass): Very common and found in most pastures. They are generally palatable and contribute to a varied sward.
-
Sweet Vernal Grass (Anthoxanthum odoratum): Gives off a distinctive sweet scent when dry. It's a low-yielding grass but adds to the botanical diversity.
Happy Gut, Happy Horse!
Think of your horse's digestive system as a finely tuned ecosystem. Their hindgut is teeming with billions of microbes, each playing a vital role in breaking down fibre and extracting nutrients. These microbes thrive on diversity. If your horse is constantly eating the same type of grass, it's like only feeding one type of beneficial bacteria – the others can start to diminish.
A variety of grass species means a wider range of fibres, sugars, and nutrients. This encourages a more diverse and robust microbial population in the gut. What does that mean for your horse?
-
Improved Digestion: A healthy gut microbiome is more efficient at breaking down food, leading to better nutrient absorption.
-
Reduced Risk of Digestive Upsets: A more stable and diverse microbial population can better cope with minor dietary changes and is less prone to imbalances that can lead to issues like colic or hindgut acidosis.
-
Stronger Immune System: A significant portion of the immune system resides in the gut. A healthy gut means a stronger, more resilient horse.
Healthy Hooves
You might not immediately connect grass with hoof health, but the link is absolutely there! Hooves are a reflection of a horse's overall health and nutrition.
-
Nutrient Availability: Different grass species offer varying levels of essential vitamins, minerals, and trace elements that are crucial for strong hoof growth and integrity. For example, some grasses might be richer in silica, which is important for connective tissue.
-
Reduced Inflammatory Responses: As mentioned with Ryegrass, some modern grasses can be high in rapidly digestible carbohydrates (sugars), especially at certain times of the year. For sensitive horses, or those prone to laminitis, this can be a real trigger. A wider variety of grasses, including more fibrous, lower-sugar options like Timothy and Fescues, can help mitigate these risks and reduce inflammatory responses that can impact hoof health.
-
Improved Blood Flow: A healthy gut and balanced nutrition contribute to overall circulatory health, which is vital for delivering nutrients to the hooves and maintaining their condition.
What Can You Do?
So, how can you introduce more variety into your horse's diet, especially if your paddocks are predominantly rye-grass?
-
Consider diverse seed mixes: When reseeding or topping up paddocks, look for seed mixes specifically designed for horses that include a wide range of fescues, bents, timothy, cocksfoot, and even some beneficial herbs like plantain or chicory.
-
Manage grazing: Rotate paddocks to allow different species to flourish. Avoid overgrazing, which can weaken less dominant species.
-
Embrace "weeds": Many common "weeds" like dandelions, plantain, and nettles (once wilted) are actually highly nutritious and beneficial for horses. Of course, always be sure of what plants are in your paddock and remove any known toxic ones like ragwort.
-
Supplement strategically: If paddock variety isn't an option,and lets face it for most of us it isn’t, ensure your horse's diet is balanced with a good quality Balancer that provides any missing nutrients. Look closely at some of the ‘grass chops’ that are available. Some brands, such as Simple Systems, use a variety of different grasses which make adding grass variety into your horses diet so much easier.
By thinking beyond just "green" and striving for "varied" in our horse's grazing, we can make a significant positive impact on their gut health, hoof quality, and overall well-being. Your horse will thank you for it
