Question about horse manure

[marlingardener]

Cattle have very inefficient digestive systems, much worse than horses. If composted, the manure heats up enough to take care of most of the undigested seeds. The others can be taken care of with a judicious application of a hoe. The manure we use (and compost and age for six months) hasn't resulted in weeds taking over the gardens, but it is steer manure.
I wouldn't think that horse manure would be a weed factory, but there is one sure way to find out. Let us know . . . .

@MaryMary , thank you for your mad research skills!
I think it will be fine. I will post any interesting information to this thread later... We're still a good three months before a safe planting date date here, but I have the weekend off and plan on walking dogs and picking up some horse poop.
