I read about it, researched, etc........because a hay man was growing it across the street from me and I try to get some local hay. In my part of the country we are subject to sporadic showers (heat & only 50 miles from ocean) and fairly high humidity quite often. So you have to use a hay that cures quickly. Bermuda does well here both as pasture and hay (if you raise right type) .
From what I read, can be good hay. Teff does not winter over, so it's planted each year -- but, it also have very fine leaf. Now bermuda has fine leaf but much more of it! The observation I made was that when cutting just prior to seed out, the spires that carry the seed is also quite fine. This makes it a fairly good thing for the small mouths of minis -- finer roughage. However, I like the nice green color of dry orchard (LOVE the western & Canadian hays!!!) Local bermuda can keep decent color if raised/cut/cured right.
Horses seemed to like the taste but, I did not like the brown.
So, when he did the 2nd cut, I checked and it wasn't really better in leaf, so I chose not to get any.
We have gotten timely and adequate rains here and my pastures are beyond what my animals can consume........not always so lucky........but, not enough to have any hayed. So, I cut them
and graze them. Not complaining. (15 acres & 37 minis)
Ahhhh...winter will arrive and I'm saving for hay right now! Good grass & less grain helps with the hay $$
There was an article put out from Texas - the poor winter or whatever the reason - the hay did end up producing arsenic or cyanide - I don't remember which right now - but it killed whole herds of cows. Please do your research thoroughly. I did post sometime ago about this.
I tried the teff hay. One of my mares was very allergic to it. She had hives all over her body and she and another mare lost muscle mass across their shoulders and back. I had 20 bales of the stuff and ended up selling it for 1/2 of what I bought it for just to get it gone. Within 2-3 days of selling the teff hay and cleaning up every scrap I could find the hives went away and they both started looking better.
The Horse.com has a new research study on mature Teff hay that might interest people. The last part is the most interesting. Also the fact that they didn't use early cut Teff, it is I think a cool season hay.
I love teff hay, wish I could get some more, a few years ago my hay supplier was bringing it in from Canada. My horses LOVED it and looked terrific on it. It looked bland in color, but my guys ate it with gusto and their weight was perfect on it. I just got some hay and am not happy with it, too rich and has a bit of alfalfa in it which my guys don't need. Anyway, my 2 cents, clean teff hay can be great.
