Maybe that's because I'm not as up to speed on what it takes to ruin hay,
Thats probably it exactly. Some people automatically turn down perfectly good hay just because it has had a rain on it. That is your option of course, but if you knew about putting up hay you would know that rain on the hay shortly after cutting does not automatically ruin that hay. It doesnt automatically mean that the hay will be moldy, or musty or even than it will smell bad, it doesnt automatically mean that the hay will be low in nutrients and it doesnt mean that it wont be horse quality. It could mean any of those things, if the hay producer doesnt let it cure properly before baling. I would point out that if the hay producer doesnt let the hay cure properly before baling its very possible that the hay will be poor quality/musty/moldy/unsuitable for horses even if it didnt have rain on it prior to baling!!
If the rain comes later, when the hay is dry, as I already said that is more likely to do more damage. If the hay is down and gets multiple rains on it…if the hay is raked (especially if two swathes have been raked into one in preparation for balingbecause then the hay is thicker & will take longer to dry if it gets wet) and then gets rained on, that will cause more problems.
I have fed hay that has had rain on it after cutting & before balingyet I have never fed moldy/musty hay to my horses. I dont even believe in throwing out a moldy batch of hay & letting the horses pick through itI pick out the spoiled part (in the case where theres one spoiled spot in the bale) or throw the bale out completely (in the case where the mold is here & there throughout the bale). When I put out round bales I pull the moldy bottom portion off the bale & haul it out of the pasture rather than leave it there. So yes, I am picky about the hay I feedvery picky compared to many people that I know!
In all honesty, Ive had rained-on-once hay that you would probably not recognize as rained on if someone didnt tell you it had been rained on. And, of course, Ive seen rained on hay that I wouldnt touchjust as Ive seen non-rained on hay that isnt worth having.
We also do not have any horse quality options around here for anywhere close to $2/b
We dont either. Thats why I said I only wished that I could get some at that price! Oh, actually I could get someit was advertised at $2 and I was told I could have it for $1.50 (a friend of mine has it). Its a grass mix hay and while I have no doubt the quality of hay is good the bales wont be real big and Id have to drive an hour to get there, then pick it up out of the field (and I hate that, its a lot of workdid it for years, now prefer to load from a stack. Old age I guess?) and drive home. Since I have only my ½ ton to haul with I couldnt put on a huge load, and what I save in hay price would be made up for in gasI decided I simply dont have the time to mess with that so passed on it. In recent years Ive been paying $4 to $5 per bale for horse quality haybut Ive also looked at hay that was moldy and/or weedy crap that was also priced at $4 and $5 per bale. Just like with horses, a higher price doesn't guarantee quality! I dont go by price & I dont go with the word of the hay seller, unless its a seller that Ive dealt with before and know that he can be trusted to be accurate in his assessment of hay quality.
Should add too, just to leave nothing to assumption…we have a very low incidence of colic, so our hay choices havent been causing our horses any health problems!
As an added thought about alternatives to hay--the one and only time I bought bagged hay it was being sold in a local tack store as an experiment--and that proved to be the crappiest "hay" I've ever bought. It was COARSE and so horribly dusty, and brown colored--the horses didn't want it & it sure wasn't what I wanted to feed! The store never brought any more in, and bagged hay has not been available in our city since then.
