my 7 month old colt

Yep k thanks. I have had many underweight horses that do need water to help gain weight but lets not get into that, I do know when to stop bottle feeding him, I stopped last week due to a bad injury to my arm. But thanks anyways:)

I would like to get into that...I'm all about being enlightened with new information. But as I understand the science about why animals (us included) need water is not to aid in weight gain

Water does the following.....
An ideal lubricant to transport feed.......an aid in excretion.......a regulator of body temperature......and regulate pH (acidity or alkalinity) of body fluids.

It does not encourage weight gain in the sense, that if you force more water into a horse it will gain weight. So again enlighten me.

I sense some defensiveness in your posts? Not sure why...you posed a question and people responded, but you fired back with "I knows" and I don't think "so's"...

Also sorry im confused you said you stopped bottle feeding him last week? But yet you only posted yesterday that you were still bottle feeding him?? Sorry just confused.

Again glad he is drinking on his own.

Hes probably afraid of the bucket.

My colt wouldnt eat out of a bucket unless it was a low sided pan for a while.
