It is a subject of alot of debate. No two people view each case of ‘maintenance’ the same.
MANY people give horses they are showing anti inflammatories, joint injections and chiropractic so that they can continue to show the horse. And you can’t tell these folks that they are doing something wrong. They will tell you the horse ‘needs’ these things to be ‘comfortable’, when the reality is that they want to show the horse, and so the horse isn’t visibly off on show day, they are going to do whatever they have to do to make that happen.
People vary in how they view this. If the horse is an aged ‘packer’ for a little child to go around and step over crossrails at a local show, people tend to be more tolerant of ‘helping’ and ‘making the horse comfortable’ (only if it’s not beating their kid!). If the horse is for an adult, is moving up, is in a more aggressive program, ,then people tend to not like it.
The harder the horse is working, the more prestige or benefit he is garnering for the owner, the more aggressive a program he’s in, the YOUNGER he is, the more the tolerance goes DOWN.
Taking the emotion out of it, there probably isn’t a lot of difference between the two. There’s a point at which the pony at the local show is being ‘maintained a little bit too much’ too.
Many, many people give various injections, chiropractic, and other medical treatments, including ‘borderline’ things that aren’t exactly viewed as ‘treatment’, such as magical supplements, to many horses that don’t need them, as ‘preventatives’ and feel very, very good that they are ‘helping’ the horse. There is no medical evidence than any of these things help horses, but if you say that, you will be jumped on by a self righteous person who is very happily convinced he is ‘helping’ his horse, and a lot of salesman got him to that point through ALOT of hard work and advertising.
To clarify, adequan is NOT a ‘joint injection’. It is given in a muscle, and it generally improves joint fluid that has been affected by inflammation. In some animals, it does absolutely nothing at all. it simply doesn’t work in some animals.
There is no evidence it is a preventative or improves a healthy horse’s overall athletic career. In the presence of normal joint fluid it probably does nothing at all. It does not make ‘super joint fluid’ and horses in training should not have ‘a low level of joint inflammation’ simply due to ‘wear and tear’ or ‘exercise’ that needs to be ‘fixed’ by adequan. I think adequan is great and even human friends use it on ageing knees that have had multiple injuries and are in generally bad condition. But a little study of what it does and how it works would make anyone doubt it could possibly be a ‘preventative’ or ‘enhancer’ or ‘a little bit of help’ for a healthy horse.
