Measurements relationship among compost bedded pack barn farms in six European countries during the winter and spring season

Compost bedded pack barn (CBP) is a housing system for dairy cows, which consists of a large area covered with bedding materials where the cows can rest and exercise freely, associated with a feeding area with solid floor. Some vantages of this alternative system are the comfort provided to dairy cows and the possibility to reach higher milk yield. The aim of this paper is to present preliminary results to compose a diagnose of 20 CBP farms measurements in terms of bedded area space per cow, air temperature and relative humidity, pack temperature and pack moisture, collected in six European countries (Italy, Germany, Austria, Sweden; Slovenia; The Netherlands) during the period between November 2017 and May 2018, in order to describe eventual relationship among the farms.
