Why interior of a cowdung pile kept for few days is quite warm?

The interior of a cow dung pile becomes warm due to the process of microbial decomposition. As microorganisms break down the organic matter in the dung, they generate heat through metabolic processes. This thermophilic activity is particularly pronounced in the initial stages of decomposition, leading to elevated temperatures within the pile. Additionally, the insulation provided by the outer layers of dung helps retain this heat, keeping the interior warm for several days.
