Milk production is increasingly modernized as a result of the growing demand for food
around the world. Improvements in livestock facilities are observed, with a large increase in the
use of feedlot systems such as the Compost Dairy Barn. Increasing milk production in
confinement systems has also raised concerns such as the management of wastes (water, faeces
and urine) from the system, which has become one of the most important issues in the intensive
dairy farms. The aim of this work was to estimate the amount of manure present in compost dairy
barn systems in order to size the manure storage. The study was conducted at four compost dairy
barns in southern Minas Gerais, Brazil. These compost barns had different bedding materials and
dimensions. In each farm, data on milk yield and quality (daily production, fat and protein
content), animal weight and amount of feed ingested by the animals were collected. Total-day
manure delivered by the cows in the feeding alley and milking parlour was piled up together and
weighed. Based on the results, it was observed that, in the compost dairy barns, only part of the
total manure produced per day was delivered in the milking parlour (1.6 and 2.0%) and in the
feed alley (27.6 to 49.3%). These results are very important for designers for the proper manure
management system design of the dairy farms.
