As a general rule, horses won't eat the grass that grows in horse manure anyway - they will avoid it until there is not much else left. That has been my experience as well as what I have read on the topic.
If you are worried about the quality of feed and hoping to improve it by fertilising, it is definitely worth getting your soil tested and then topping up what you actually need in terms of minerals and other nutrients, rather than manuring the paddocks.
If you are instead wondering about the management of the grass, in terms of if you should pick the manure up or just leave it, that depends on the size of the pastures. I would pick it up if the pasture was not massive, but in a large paddock I would leave it for the most part if that makes sense. Also, if you are worried about what to do with it once you have picked it up, see if you can get hold of some old feed bags. Scoop it directly into those bags, and when you fill a bag, ask around to see if any local gardeners want free pre-bagged poop. For a few extra seconds work, you make it far more attractive for someone to come collect it, as they don't want to shovel it themselves.
Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.
