Family farm Kuštrin is specialized in milk production. Dairy cattle are kept in a technologically old-fashioned tied-in housing system. The farm is considering renovating and adapting the barn to provide better conditions for dairy cows and young stock because the conditions in the current barn are not animal-friendly and people find it hard to work there. This bachelor’s thesis explores various housing systems for dairy cows and young stock, and analyses important functional areas in the barn construction. The second part of the thesis examines the current farm conditions and presents a proposal to renovate the barn to make it more comfortable for the animals and facilitate work for the family members. This proposal would convert the barn into a free-stall housing system. The plan envisages a barn for thirty-five dairy cows and thirteen heifers twelve to twenty-eight months old. An additional structure would be built next to the current barn and connected to it in the most functional way, possibly to provide room for calves and young stock up to one year old. The manure alley floor will be made from solid concrete and cleaned with alley scrapers. A fish-bone milking parlour (a 2 × 3 layout) will be used for milking. The thesis also proposes a setup for young stock.
