Nightprowler are you using it indoors? Horse shit is excellent, I've known one guy...., ,, that I know,... , that goes for horse shit other everything else, something about it being less concentrated and very hard to burn young plants with. All I know is that fresh horse shit outdoors should take at least six months until most of its organic properties become properly available to the plants, you should mix it with some other soil light in nutrients and wait. I don't think it would do much good going straight from the horses ass to the pot.
