Sunbleaching or Sweat?

As a lover of chestnut horses, and a nutritionist, sunbleaching had frustrated me for YEARS!

My gelding Poet, a stunning almost liver chestnut in the spring, would bleach to a homeless looking colour by the end of our hot summers… leaving me wondering if perhaps his mineral balance wasn’t quite right.

That was until one particularly hot summer when Poet and I did an unintentional experiment over our Christmas break… which seemed to show that the sunbleaching that occurs in some horses over summer is a combination of sun and sweat.

Do gastric ulcer medications affect digestion?

A racing client asked me this recently and it reminded me that when I was studying during my PhD tenure, we had looked at the effect of pre-incubating grains in pH 3.7 equine stomach fluid on the digestion of starch from those grains.

And what we found was that starch from grains that were exposed to equine stomach fluid before being digested by small intestinal enzymes was between 17% (extruded rice) and 104% (cracked triticale) MORE digested than starch that wasn’t exposed to the stomach fluid.

What are enzymes?

When a horse eats, much of its feed is made up of LARGE carbohydrate, fat and protein molecules. These large pieces of nutrient can’t be absorbed because the gut is designed to only absorb tiny little molecules. 

Why? Because if big stuff was able to cross from the gut into your horse’s body all sorts of bacteria, toxins and general muck would pass into the body and cause disease havoc!

How to use salty water to keep your performance horse hydrated

Keeping performance horses and particularly endurance horses hydrated can be a massive challenge. And a big part of the challenge is that horses have a rather inconvenient thirst response trigger.

For horses to ‘feel thirsty’ they need a certain level of sodium in their blood. BUT when they drink fresh water, it dilutes their blood sodium and that can switch off their thirst response, even if they are still dehydrated! Which means you can have a dehydrated horse that isn’t actually ‘thirsty’! See … told you it is inconvenient.

Stabling and ‘Slow Work’ Increases the Risk of Bone Injury in Racehorses

Long periods of slow work for racehorses has long been thought of as the best way to ‘leg up’ young horses, preparing them physically for a life of racing.

BUT, three decades of research conducted by Professor Brian Nielsen of Michigan State University and his team and students is telling us, definitively, that we have got it all wrong and that speed is essential for bone health!

Feeding the child’s mount

There are few equines I respect more than an amazing kid’s horse or pony. The patience these creatures have with their precious little cargo is incredible. And their ability to meet their little riders where they are at is something that always staggers me.

Being a reasonably rare commodity, we want to do everything we can to look after our childrens’ horses and ponies to keep them, fit, mobile, healthy and happy for as long as possible.

Here are my 5 best tips for feeding your child’s mount.

Feeding horses for calm behaviour

As a rider, it really is hard to top the feeling of a ride on a horse with beautiful calm, yet responsive energy. And for most of us, there is nothing quite as unnerving or unenjoyable as riding a horse that is completely full of itself and constantly reacting before thinking.

Should you feed more to a horse that feels tired and lazy?

Well… it depends! If your horse is light in condition and possibly losing some weight and feels tired and lazy then yes, feeding more is probably the solution. BUT! If your horse is overweight or gaining weight, more feed is not the answer to overcoming your horse feeling tired or lazy when being ridden.

Horse digestive system: equine gut health

The gut health of our equines plays a significant role in determining how healthy or unhealthy our horses will be. The equine digestive tract is a large and relatively complex system. Your horse’s health depends on how well you look after this digestive system and importantly, how well the microbial population within it remains “balanced”.

Feeding the laminitic horse

Laminitis is horrible. It is distressing and painful for your horse or pony and it is gut-wrenching to watch as their owner. And if you are anything like me, it also creates a feeling of guilt…  the ‘how could I let this happen to my horse’ kind of, keep you awake at night, guilt So, for both our equines and our own sakes, we need to understand laminitis more so we have a better chance of preventing it in the future.

Preventing Gastric Ulcers in Horses

Equine gastric ulcer syndrome (EGUS) is a major equine health problem worldwide. Multiple studies have reported a 90% incidence rate of ulcers in performance horses.

Ulcers negatively and sometimes severely affect a horse’s ability to perform. They cause pain and discomfort. They may reduce your horse’s appetite which in turn limits their capacity to maintain bodyweight and ulcers can lead to the development of vices like windsucking and crib biting.

While gastric ulcers have long been recognised as a major health concern there is an evident lack of understanding in the horse owning community about what causes them and how they can be prevented.

Starch & ulcers: What’s the deal?

You may have heard it recommended that horses with ulcers should be fed a ‘grain-free’, low starch diet. It is believed that any starch may make ulcers worse. Or stop them from healing when the horse is being medicated to resolve ulcers. But is there any scientific basis for what has now become a popular recommendation? Let’s take a look!

Why cereal grains for horses should ALWAYS be cooked

Cereal grains such as oats, barley, triticale, corn, rice, rye, sorghum and wheat are commonplace in horse diets. When fed well, cereal grains form a valuable component of many horse’s rations.

But fed improperly, and they will cause large shifts in your horse’s gut microbial population, causing dysbiosis and a host of serious health and behavioural issues. Issues that can be so severe they will end the performance career of your horse and in the worst cases, even lead to death!
