We have had good results using horse manure on rhubarb.

Manures generally have little NPK. When you put these or other mulches in the soil, they grab all the N to break the manure down, therefore the plant has little access to N and don't grow much. In future put the manure in a pile and wet it and turn it over regularly to break it down to compost before putting it on the garden. When applying mulch over put it on about 50mm thick. Mulch 200mm thick will take a long time for water to pernitrate through to the soil.
