OVER WEIGHT HORSES AND PONIES - IT'S NOT JUST ABOUT LAMINITIS!!
With all the talk of insulin, laminitis, sugar, non-structural carbs and suchlike I just wanted to post a very important reminder...
Insulin problems and laminitis are not the only reasons we should be keeping our horses and ponies at a healthy slim body weight and condition.
(And some over weight horses and ponies do not have insulin issues or laminitis, regardless of what they eat, possibly because they are not genetically predisposed).
Excess condition i.e. weight from adipose tissue (f4t)/obesity increases the risk of a number of other health issues too, including:
> strangulating lipomas (balls of fat on strings of gut tissue which can literally wrap around the gut, creating a tourniquet, and can cause fatal colic)
> hyperlipaemia, which can be fatal
> disturbed/abnormal appetite
> whole body inflammation, which might contribute towards a range of health issues including osteoarthritis, equine asthma, heart conditions
> arthritis and other joint disease
> exercise intolerance
> potential increased risk of liver, kidney and other organ disease (if we extrapolate from human research)
F4t is an active body tissue, not just a store of energy, and it secretes pro-inflammatory hormones as well as being associated with insulin dysregulation.
Some of you may have read information that you don't need to worry about obesity if you keep your horse on a low sugar diet because it's the sugar intake only that causes insulin issues and laminitis, BUT that info has missed out the VERY important factor that it's not just insulin and laminitis we should be concerned with !!
It may take some years of chronic obesity for health issues to surface, so don't assume that your obese horse or pony is safe because they don't have any obvious health problems right now.
