Hi there,
I am new to this forum and have a question regarding the need for increased water intake while soaking hay.
Background: My horse (16 year old Arabian gelding) had a couple of episodes of impaction colic this last December. The first episode required a vet, hydration, and Banamine, whereas the second episode just required encouraged hydration (salt, bits of small dry hay). He also went off his feed for a morning 2-3 weeks after the 2nd episode, but wasn’t ‘colicky’. This was the first time(s) he had ever had colic (we’ve had him since he was a foal), and so it was pretty scary! Since the first episode, we have been increasing his salt intake (now 2 tbsp per day), and are feeding him hay every 2 hours - from 8am to 8pm. He also gets small quantities of beetpulp mash 3 times per day, which includes soaked complete horse feed, soaked vitamins, some salt and ground flax. We also make sure his water is always warm and fresh.
We suspect that these colic episodes were due to dehydration. He had not been using his mineral lick (I suppose he did not like the taste?), we had not been adding salt to his feed (which we definitely are now!), and this was the first year he has had access to pasture during the winter. What we have noticed is that he doesn’t drink has much as he should - very little, while out on winter pasture. We live on Vancouver Island where it is quite wet, and he doesn’t seem to be thirsty on the wet grass. Although I would love if he could be on pasture during the winter, he just isn’t drinking like he should! So, we now only let him graze for a few hours during the day - he’s most happy with his head down, roaming around.
We experience the same problem when we soak his hay - he doesn’t drink as much, putting him at risk of impaction colic again. But on the other hand, the hay we now have is a bit on the dusty side - hence why we have been soaking it. I don’t want him to contract heaves either! However, when he eats it dry, he drinks more. So it is a bit of a catch 22 situation.
Does anyone have any thoughts or suggestions in regards to this?? Thanks!
