Colic

[Guinness]

Why is it that frosty grass can bring on a bout of colic? Also, why is it that they get pale gums-something to do with their temperature?
Thanks!

Don't know why frosty frass causes problems, but it does sometimes. As for pale gums, I have always thought that to be a sign of anaemia (often seen with low grade chronic infection)

 

[Guinness]

So is anaemia linked with colic then? I suppose if their digestion is inhibited then not enough iron is absorbed or something...?

I agree my horse had pale gums and had anaemia. We just put him on some blood liquid from our local horse & rider and he was fine. Not sure about the frosty grass

i've always thought that frosty grass causes the same problems as ice-cold drinking water, or ice-cold water added to feeds - it's the shock to the system.
pale gums = anaemia, yes. perhaps because all the red blood cells are being drawn back from the extremities to the gut? we need a vet's expertise on this one, i think!

Frosty grass retains higher levels of fructose and this increased sugar levels can cause acidosis in the gut.

Also - the gums go pale pink - I believe because the blood is being taken to support the essential organs and the gut - Also look out for blood shot or "pink" eyes - another sign of colic.

Thanks!

So I guess thats also why they say not to put laminitic horses out on frosty grass too?

 

[H's mum]

Yes acidosis of the gut has been linked to laminitic changes occuring which is why it's best to avoid frosty grass - Grass which has been subjected to warm wet weather also experiences a higher level of fructose and is another thing to avoid with horses that colic or have laminitis.
