Horsey folk clearly like haylage.  We make all our silage as dry as conditions allow and in a good year pretty much all of it is haylage - so perhaps I shouldn't worry about BH feeding it to his Daleses.

I wonder whether the embargo on silage for horses dates back to early days of bagged/wrapped silage, when an additive would be used to start the fermentation?

silage (if actual silage rather than drier haylage) is too acidic and can cause real problems. It can also cause botulism. It will also go off more quickly.

If it is the drier stuff, being used up quickly and the grass isnt cut too low then it might be ok...but I wouldnt risk it with my naglets
