I'd like to clear up something that was in FHotD today. Here is her quote to shortly sum up my major eye roll-
the sugars upset the normal balance in the horse's digestive tract, resulting in toxins which lead to founder, aka laminitis
First, lets all get this straight since most people are led to believe that founder and laminitis are one in the same. While most google searches will bunch founder and laminitis together, they are actually two completely different things. While I feel that every first time or novice horse owner should know about grass or grain founder, it is also important they aren't led on to believe inaccurate information or that those are the only causes of either laminitis or founder.
Laminitis is the infection and inflammation of the laminae. Founder is the resulting rotation after the laminae breaks away from the hoof wall and the coffin bone rotates down towards the sole. Laminitis does not always lead to founder and there are simple steps you can take to make sure that your horse does not founder. Here is my simple list on how to treat laminitis before actual founder occurs. This is not to say that prevention of laminitis is not key in keeping your horse healthy and sound, these are just tips in case it does happen.
Call your vet immediately as it is important to take action as soon as you notice- knowing the signs or being able to tell a difference in your horse are major role in this
Soak your horses feet in cold water. If you are able to get your horse to stand in ice water. This will help prevent that inflammation that leads to laminae necrosis.
Your vet will most likely suggest a pain killer and anti-inflammatory such as phenylbutazone or ketoprofen. If you have bute on hand, administer according to your horses weight.
If your horse wants to lay down, let him. This will relieve the pressure that is on his feet.
Your vet may suggest to keep with bute for 48-72 hours, make sure your horse is as comfortable as possible.
Encourage movement to allow blood flow if your horse is comfortable enough to walk. No circles or sharp turning.
Make sure your horse is in a area with soft ground to relieve the feet.
Treat abscesses as soon as you can
Gone untreated-laminitis can lead to founder. Grain and grass are not the only reasons laminitis and founder occur.
Road founder also known as mechanical founder occurs when a horse is worked for extended periods of time on hard surface
Laminitis can also happen if a mare retains placenta for over 12 hours causing an infection
Colic can lead to laminitis
Drinking large amounts of water after a hard workout without properly being cooled down
Bedding with walnut shavings in it
Cushings and other insulin resistance
Immune, respiratory, and renal problems
I post this because beginners are often misled and need to be aware that grain and grass are not the only culprits needing to be watched for.
