This work classifies dairy farms that use Compost Barn (CB) as a confinement system for dairy cows in the Mission Region of Rio Grande do Sul / Brazil. The Support Center for the Development of Milk Products and Processes installed in the Technological Park of URI Santo Ângelo aims to provide support to companies and milk producers in the region covered by TecnoURI. It is presented in this article that the study of the evaluation of the Compost Barn (CB) system used by milk producers of cooperatives in the Missions region of Rio Grande do Sul, which presents itself as a promising alternative for the production of raw milk, bringing better quality and welfare for the animals present in this system. This research identifies structural and handling factors that interfere with the quality of composted packaging. The data were obtained on the spot, with measurements of facilities, observations of herds and collection of technical information on dairy farms. In addition to the consolidated variables related to the handling and quality of the packaging, it is reported that the frequency of agitation, resting area per animal, presence of mechanical ventilation in the barn, the type of material used to compose the bedding package and the local relative humidity are factors that influence the main bed variables of the Composto Barn system and can be key points for the success of the CB system in subtropical regions of Brazil. This article presents the results of the study of the evaluation and improvement of the compost barn system of milk-producing members of cooperatives in the Missions region of Rio Grande do Sul, aiming at decreasing the milk CCS, as well as the identification of the microorganisms that cause mastitis. The influence of management on the quality of the bed is evident, mainly regarding the frequency of turning, correct dimensioning of the bed area, and the presence of a ventilation system. However, the good functioning of the system depends to a large extent on the adopted daily managements, which still need to be studied for a better understanding of the composting process, a key factor for success in production.
