Basic Unit Cost Simulation From Free-Stall Design to Dairy Cattle Confinement Using Different Construction Techniques

Abstract

ABSTRACT:The ascendancy of milk production in Brazil is due to mainly to the adoption of confinement systems, however, construction quality of these systems impact on milk production. This study aimed to simulate the Basic Unit Cost (BUC m -2 ), referring to a free-stall design with capacity for 80 animals and different construction techniques, with a database for various budget analysis and investment plans. A budgetary spreadsheet was modeled, allowing simulating the BUC m -2 for different combinations of roof pillars (metallic, wood or reinforced concrete), covering structure (metallic or wood), coverage model (with or without ridge vent), roof tiles (aluminum, cement or ceramic) and masonry (concrete block, ceramic or solid brick). The techniques used were compositions generated by Price Compositions tables for Budgets (TCPO, 2014). The results relating to 2014 and expressed in unencumbered values showed the maximum variation of 29% in the BUC m -2 , establishing a range of R$ 523.96 m -2 to R$ 675.98 m -2 for the free-stall construction.

Representativeness of the field of rural buildings and ambience in Brazilian journals / Representatividade do campo dos edifícios rurais e do ambiente nas revistas brasileiras

“…In the last few years, food production has significantly increased, as well as the regulatory requirements of the producing countries and of all sectors that commercialize agricultural products [1][2][3][4][5][6] , searching for a cleaner and more sustainable production, with less impact on the environment and meeting animal welfare guidelines [7][8][9][10] .…”

“…The impact that a rural production building can cause on the production process itself, on the product and the workers, is very expressive. Especially in animal production, the quality of the physical environment 2,3,11,12,[21][22][23][24][25][26][27][28][29][30] (rooms, population density, construction materials, the ease of nutritional and sanitary management) and the quality of the indoor environment (pollutant gases, particulate materials, microorganisms, temperature and relative humidity, ventilation 11,[31][32][33] ) are distinctive factors in the quality of the process and product.…”
