It’s important to exercise caution though, because overfeeding on grass when it’s rapidly growing can lead horses to founder.

Is laminitis worse in spring?

The reason the risk of laminitis increases in the spring is that as the days get longer, the extra sunlight increases photosynthesis, which results in starch, sugar and, in some plants, fructan production.

How long can horses be on spring grass?

As well as the time restrictions, it is also a good practice to feed horses their normal hay diet before turning them out to pasture during the first several grazing days of the year. This will slow down their eating of the pasture grasses. Once 5 hours is reached, the horses are safe to stay out as long as you like.

Why does spring grass cause laminitis?

In spring, when horses consume the lush grass, the extra starches and sugars ferment in the horses’ gastrointestinal tracts. This fermentation affects the balance of bacteria in the GI tract, which in turn can trigger laminitis.

How do I stop my horse from foundering?

To avoid grass founder:

1. Allow the horse to fill up on hay before turning out on grass for a few hours.
2. Place a grazing muzzle on horses predisposed to foundering to limit their forage intake. Grazing muzzles limit grass intake but allow the horse to exercise throughout the day.

What months are worse for laminitis?

Spring is traditionally known as a peak time for laminitis, but the latest research shows that the second biggest killer of horses and ponies is an all-year-round threat.

Can horses colic on spring grass?

Spring grass, low in fibre is rapidly fermented, and an overload of starch enters the cecum killing off microbes important to digestion. Kapper says, “The first sign you will see is a loosening of the stools.” When excessive fermentation creates a buildup of gas in the gut this is when gas colic can occur.

Can horses eat spring grass?

But why is it so critical to closely manage our horse’s time out on grass in spring? The answer is simple: new spring grass is typically high in particular nutrients called fructans – to which your horse’s digestive tract is unaccustomed after a long winter on hay and which can be hard on the hindgut.

Can spring grass cause ulcers in horses?

Endotoxins and exotoxins could then enter the horses’s system, leading to colonic ulcers, laminitis, and even colic – in any horse.

What should a foundered horse not eat?

How do you manage horses in spring grass?

Methods for Transitioning to Spring Pastures
Once the pastures are ready to graze, begin with short grazing periods for the first few days (15-30 minutes per day). Slowly increase the grazing periods by an additional 15-30 minutes per day until the horse is grazing for 3-4 hours daily.

Whats the best graze time for a laminitic horses?

between 3 a.m. and 10 a.m.
Susceptible horses should graze between 3 a.m. and 10 a.m., when plant sugars are lower. Plants collect sugar in times of stress such as during a drought or when temperatures fall below 40° F. Don’t graze susceptible horses during periods of plant stress.

Can a laminitic horse ever have grass again?

A return to some access to grass will often be possible following laminitis or for a horse with EMS/ID, as long as something – whatever caused the laminitis – has changed.

What time is sugar highest in grass?
