Measuring the moisture content of the litter layer and determining the amount of straw spread should provide information about the sufficient amount. Furthermore, it is examined how the increasing thickness of the litter and manure layer affects the amount of litter and the moisture content of the litter layer. It is to be expected that the daily amount of litter can be reduced as the thickness of the litter layer increases. Another goal is to clarify the question of how the animals' body weight affects the amount of bedding. Larger and heavier animals consume more food and water and therefore produce more excretions. The connection between body size, feed intake and amount of bedding should be clarified. From this point of view, information about the daily amount of straw per animal can deviate far from the actually sufficient amount.
