In cattle farming, planning a barn is a decision a farmer makes only once every few decades, so it is worth thinking through the space for each animal, air circulation, and the paths to feed and water well in advance. PATURA has compiled functional dimensions for this, proven in barns across Europe, and Kancler Sistem Pro, as its Slovenian partner, turns them into concrete solutions for local farms.
Step 1: start from animal comfort
A high milk yield over a cow's longer productive life is only possible if comfort in the barn is genuinely provided. That means:
- space designed for animals with broad shoulders
- a cool barn with fresh air circulation and no draft
- comfortable lying on rubber mats or bedding
- well-accessible drinkers
- non-slip walking surfaces without sharp edges and good manure removal
- adequate lighting and animal care with brushes
- a quiet area for passageways and for cows around calving
Step 2: dimensions of lying stalls
For a dairy cow barn, the following guideline dimensions apply: lying stall length 2.70-2.80 m (2.30-2.50 m in a double row), width around 1.25 m, depth to the brisket board around 1.85 m. The stall-to-animal ratio should be 1:1. The walking area for lying should be 2.50-3.00 m wide, the alley at the feeding place 4.00-5.00 m, the cross alley around 2.50 m, and the cross passage with a drinker 3.00-4.20 m.
Step 3: the feed place and the manger
The feed place to animal ratio should be between 1:1 and 1:1.2, with a feed place width of 0.65-0.80 m. The manger should be 50-55 cm high, or 15-20 cm measured from the feed table, and the neck rail height should be around 1.25 m. These figures are not arbitrary: the feed table has to be raised relative to the standing area, because on pasture an animal shifts one leg forward while eating, which it cannot do in a barn, giving it a shorter reach to the feed.
Step 4: young cattle grow, so dimensions change
For young cattle, dimensions need to match the animal's age and weight. For animals aged 4 to 6 months (130-200 kg), the lying stall should be 75 cm wide and 150 cm long; for 7 to 12 months (200-350 kg), 95 cm and 180 cm; for 13 to 18 months (350-500 kg), 105 cm and 200 cm; and over 18 months (over 500 kg), 120 cm and 230 cm. The feed place width grows in step, from 40 cm for the youngest animals to 70 cm for adults.
Step 5: choose the barn type for your kind of production
Bull fattening commonly uses a barn system with concrete slatted floors, where the animal-to-feed-place ratio is 2:1 and a group should not exceed 16-18 animals. The lying area per bull ranges from 2.00 m² at a weight up to 350 kg to 3.00 m² above 650 kg. An 80-90 cm wide passage behind the pens is also recommended for safely moving animals.
For suckler cows, a different layout makes sense: a deep, tread-through bedding system with a lying area depth of 4.00-7.00 m and a lying area requirement of around 4.50 m² per cow plus 1.20-2.00 m² per calf. The alley at the feeding place should be 3.00-4.00 m wide, and the slope of the lying area 5-8% (or 6-10% at a shallower depth). For larger groups, it is advisable to divide the space with intermediate telescopic partitions to prevent animals from pushing each other. Support posts in the area where animals tread down manure are not recommended, since they obstruct manure flow.
When raising cows with calves, it is important to include in the plan a separate area for calves that they can use right after birth and that adult animals cannot access. The same applies to the calving area and the area for dry cows, which should be planned separately from the rest of the herd by sex and production stage.
Checklist for barn planning
- The lying stall-to-animal ratio is 1:1, and the feed place-to-animal ratio is 1:1 to 1:1.2
- The feed table is raised relative to the standing area, and the manger is high enough that feed does not fall onto the table
- Lying stall and feed place dimensions match the age and weight of the animals, not a single size for the whole herd
- The barn allows fresh air circulation without draft
- Intermediate partitions are planned for larger groups to prevent animals pushing each other
