horses ever. Horses have a very ineffecient digestive tract so almost all
seeds pass through and can than sprout and become your next weed problem.
Composting it will hgelp a lot. 

Also check to see what kind of wormer they are using (99.9% od US horse
owners use chemical wormers instead of DE) Ivermectin (a paste given every 4
to 8 weeks orally) can kill most of the microbes responsible for composting
so that should be avoided, though I have used a lot of horse manure from
horses that I had personally administered ivermectin too and had pretty good
compost piles.

The pine shavings can put too much acid into your soils if you tend towards
acid soils. If you live in the midwest the pine shavings would be an asset
for the base soils there.
Pine can also bind up N pretty badly so go easy on the shavings or add some
chicken manure to add more N.

That's my 2¢ on horse poop
