The risks of spring grass for horses

As the days get longer and temperatures begin to rise, the grass in the fields starts growing rapidly again. For many horse owners, this is an exciting time: horses can spend more time outdoors and enjoy fresh grass. However, spring grass also comes with certain risks. During this period in particular, it is important to manage grazing carefully to help prevent health problems in horses.

Why can spring grass pose a risk?

In spring, grass grows rapidly and often contains high concentrations of sugars, including fructans. These sugars are produced as grass stores energy through photosynthesis.
Fructan levels in grass can rise considerably, particularly on sunny days followed by cold nights. This means that grazing horses may consume large amounts of sugar in a relatively short period of time. Not every horse can process these amounts equally well. Native and easy-keeping breeds, ponies and overweight horses can be particularly sensitive. Horses with a history of certain health problems may also be at increased risk.

Laminitis: an important risk

One of the best-known and most serious risks associated with excessive sugar intake from spring grass is laminitis. Laminitis is a painful condition in which the connection between the hoof wall and the pedal bone becomes weakened or damaged. It can develop suddenly and, as well as causing considerable pain, severe cases can result in permanent damage to the hooves. Prevention is therefore extremely important.

How can you introduce grazing safely?

Fortunately, there are several measures horse owners can take to reduce the risks associated with spring grass:

• Introduce grazing gradually. Allow horses to graze for short periods at first and gradually increase the amount of time they spend at pasture.
• Keep an eye on your horse’s weight. Overweight horses are at greater risk of developing health problems.
• Take extra care with sensitive horses. Ponies and easy-keeping breeds often require less than larger sport horses.
• Choose the right time for grazing. Sugar levels in grass can vary throughout the day, particularly following sunny days and cold nights.
• Consider using a grazing muzzle or restricting access to pasture. This can help reduce the amount of grass your horse consumes. 

Managing grazing responsibly

Spring grass does not have to be a problem, as long as you are aware of the potential risks. By introducing grazing gradually, monitoring your horse carefully and taking action when necessary, many problems can be prevented. This allows your horse to safely enjoy time at pasture while staying healthy throughout the grazing season.

How should you adjust your horse’s ration when grazing on spring grass?

Grazing has a direct effect on your horse’s overall intake of sugars and energy. It is therefore important to adjust both concentrate feed and forage accordingly. Request personalised nutritional advice to make sure you are not unknowingly providing your horse with too much energy or sugar.
