Composting of Cattle and Pig Manure

Studies of solid manure treatment on 83 Swedish dairy farms showed that no composting process occurred in the majority of cases while high temperatures could be found in the manure in 27 of 34 piglet producing farms. It was found that at least 2.5 kg of straw per cow and day must be used to get a manure that can be composted without forced aeration or turning of the material. It was also found that the straw should be given as bedding.
