Any excrement that isn't processed by another insect or animal first needs to be composted for some time until worms/beetles, etc can eat through them and destroy the pathogens and baddies. :thumbs:
I'd buy my stuff for now, but don't feel like it's not worth your time to scoop up some of the llama and buffalo manure and compost it with some worms and other things and trying it.. buffalo manure would be close to cow manure really, and black kow is pretty cheap. :thumbs:
I'm not too familiar on llamas diets, so I can't tell you what the manure may or may not have in it.. if it's the same kind of diet as buffalo, the manure itself won't differ too much, IMO.
