Change of weather/routine, bad diarrhea in horse?

One possibility is that the sudden drop in temperature has caused the fructan levels in the pasture grasses to rise significantly so that even with limited turnout, there is still a potential overload which will cause disruption of the hind gut mircoflora. The grass can appear to be dried up and dying and yet be as dangerous as lush spring pasture if not more so.

The stress associated with restricting turnout time combined with the stress of the climate change can cause hormone fluctuations and metabolic disturbances, and suppression of immune functions which render the horse more vulnerable to infections and diseases.

You haven't mentioned checking vital signs, which should be done. If there is a temperature elevation it can signify advancing dehydration or infection, among other things, and warrants a call to the vet sooner rather than later.

Regardless, if diarrhea like this persists for more than twelve hours a vet should evaluate the horse. The risks of dehydration, electrolyte imbalance, and metabolic acidosis are serious and the horse may need parenteral fluids, electrolytes and bicarb. Realize that anything you feed orally is likely to be unabsorbed and passed in the stool when diarrhea is present.

There is also significant risk for secondary development of serious conditions such as colic or laminitis when metabolic disturbances occur, and all of the risks have to be weighed when deciding when it is time to get the vet involved.

I would notify the vet asap and let the vet advise you as to what to do. Any information you can provide over the phone will be helpful to the vet, such as description of all symptoms you are observing, vital signs, capillary refill time when you apply digital pressure on the gums, presence or absence of tenting of skin when you pinch a fold to test for turgor, amount and appearance of urine being passed and the volume of water the horse is drinking, and everything the horse has eaten and treatments you have administered.

Hopefully none of the worst case scenarios will develop, but it is important to know that they can when deciding whether or not to call the vet.

Honestly, I don't think it's anything to worry about. Monitor it again over the next few days/week, though, and see if anything changes. I have found that my horses (and a good few at work) are having the same problem at the moment, and I really think it's just due to the weather change as does everyone else. Everything gets wet - and so does their droppings! If you do ring the vet - just speak to them about it over the phone and get their opinion. Considering that nothing else has changed besides turnout, I don't think that they will be worried at all.

He may be a little stressed after the vet - it sometimes happens.

As he's been in when he's used to a fair bit of turnout, did you increase his hay to replace the grass (just momentarily before reducing it back to his normal amount)? If not, then you've upset his stomach as he's used to the large amount of grass.

Increase his hay and put yoghurt in his feed (just a cheap, natural unflavoured yoghurt.) It works for my 18 year old Connemara when he occasionally gets a little soft once or twice a year (usually when he comes in full time in winter after being on grass every night in the summer. He can't have extra hay though - he's on a diet and will just gorge himself and give himself colic. Usually it's a week on the yoghurt and everything is back to normal.)

whilst horses rigidity, frequently they get diarrhoea, have faith me my horse is an absolute rigidity-head!!! So my suggestion could be to verify she has adequate water, bandage her tail, so which you do no longer ought to constantly wash all the poo out, and placed some electrolyte (salt replacer) in her feed. it frequently is presented in a powder variety and you basically blend it into her frustrating feed. Its truly solid for changing the nutrition that she is rapidly dropping for the period of the diarrhoea, and it makes them thirsty to drink greater water. If it keeps for greater beneficial than 2 days, then call the vet out. She would go with some time to settle in. Is she now in a solid or a tiny paddock with you, by way of fact horses that are used to numerous room with a huge grassy paddock would feels slightly cooped up in a smaller residing area. basically keep offering the hay, and prefer I reported in the previous, and if the diarrhoea does not supply up after 2 days, then call the vet. BTW whilst became she final wormed, it must be by way of that as properly. wish this facilitates=)

I'm sure he will be fine. My horses get diarrhoea from the grass every now and then so i wouldn't worry about it. If your horse still have it in 2-3 weeks, i would call the vet up and ask them what you can do. :)
