Chicken Manure

Poultry manure ,chicken in particular, is the richest animal manure in N-P-K (nitrogen-phosphorus-potassium content). Chicken manure is considered to be "hot" and has to be composted before adding it to the garden.Otherwise, it will burn the plants it comes in contact with.

Dairy (Cow) Manure

"Dairy manure may be the single most useful soil-builder around," says Ann Lovejoy, lifetime organic gardener and a writer in Seattle, Washington. "Washed dairy manure from healthy cows is just about perfect for garden use; it can be used as a topdressing and for soil improvement." Dairy manure is preferable to steer manure, which has a higher salt and weed content. Though cow manure has low nutrient numbers, that's what makes it safe to use in unlimited quantities.

Horse Manure

Horse manure is about half as rich as chicken manure, but richer in nitrogen than cow manure. And, like chicken droppings, it's considered "hot". Horse manure often contains a lot of weed seeds, meaning it's a very good idea to compost it using a hot composting method.

Steer Manure

Steer manure is one of the old standbys, but it's not the most beloved bsince it often contains unwanted salts and weed seeds.

Rabbit Manure

Rabbit manure is even higher in nitrogen than some poultry manures. It also contains a large amount of phosphorus, which is important for flower and fruit formation.

N-P-K  2.4-1.4-.60 

Sheep Manure

Sheep manure is another "hot" manure. It is somewhat dry and very rich. Manure from sheep fed hay and grain will be more potent than manure from animals that live on pasture. Remember to compost it before putting any in your garden to prevent the manure from burning your plants.
