Obesity is a modern issue in horses, leading to a range of problems including laminitis, Cushing's disease, equine metabolic syndrome and other disorders. Laminitis is more prevalent in spring for pastured horses.

A growing body of research indicates that under conditions of stress, the horse’s body is “tricked” into gaining weight just to survive.

Stress points may include:• confinement• social isolation • sleep deprivation• change in environment• travel• excessive training or competing• pain and illness• exposure to toxins• Reduced access to forage for

Modern pastures, developed for high production in livestock e.g. cattle for dairy, or livestock for fattening and breeding is often too rich and high in sugars for many horses.

There is the traditional approach for having a ‘Jenny Craig’ paddock or bare area for keeping horses, which is part of a solution but not all of it.

Care must be taken not to over-restrict forage (grazing and browsing), causing stress, so that fat is placed on the horse just because of the living environment and care regimes- which might have in fact been originally designed to reduce weight gain.

A few tips:

Work out ways to promote the natural grazing behaviour of horses (constantly walking and eating) supplemented with exercise if needed. Property layout will greatly assist, as will equine friends.

Know what plants are in your paddock, and what your horse is eating (promote preferred grasses, remove toxic plants).

Use a multi-vitamin supplement (deficiencies may be identified in part by blood tests available)

Arrange for a soil test to see if deficiencies exist and may be able to be corrected.

Seek professional case management advice from veterinarians and qualified

For obesity prone horses:

Use a yard as part of an Equicentral system, or if need to for part of the season (especially with a horse that has already foundered previously).

Source hay that is low in energy, sugars and starch (less premium, without being old, mouldy or full of weeds e.g. meadow/grass hay)

Use slow feeders and other ways to prolong chewing time + promote walking. Limit grazing muzzles to a few hours.

Obesity is not the only spring flush problem.

Acute and chronic oxalate toxicity in Miniature Horses associated with

soursob (Oxalis pes-caprae) ingestion

• 14 miniature horses in six separate outbreaks presented with clinical signs consistent with acute or chronic oxalate toxicity.

• All animals had access to Oxalis pes-caprae or soursob

• Chronic oxalate toxicity was associated with ill-thrift, stiffness, enlarged heads, kyphosis and neurological signs

• these horses responded to treatment with intravenous and oral calcium.
