Where would one find that tall of green grass right now?!? I looked outside this morning at the "grass" and saw snow
I have a feeling we will be having the short frost covered grass for awhile here. Didn't MD just get snow too? Or was that just wishful thinking that we wern't the only ones cursed with that?
<sigh> at my place
The grass in the sunny spots in the pet cemetary woods was well over two feet tall, when I mowed it on Sunday.
I have mowed the parts of yard twice (three times in the dogs' back yard) and just mowed the two front horse pastures that also serve as part of our front yard.
Part of the three acre section, up by road and that is fenced off from the horses, is ready to be bushogged
Suffice it to say, my IR horse has been in a grazing muzzle since March 2nd.
As far as your horses automatically becoming laminitic from ten hours of free-grazing --- it depends, as others have commented.
I can eat a whole bag of Hershey's Kisses and nothing happens until I look at the scale.
That would be disastrous for a diabetic which, essentially is what metabolic horses are - Type II Diabetics.
So it depends whether or not any one of your horses is predisposed to insulin issues. Ten hours of grazing may or may not push them over the edge.
To be safe, I would keep them off grain, if you're not working them hard and monitor the pulse in the lower legs and heat in the hooves
