Feeder & Drinker Space & Give Every Animal a Place at the Trough
Sizes mangers
Total space = animals × space each; divide by feeder length for the feeders needed, and feeder ÷ space each for animals per feeder — so the whole group can eat at once.
Size your feeder line
Next: install 10 feeder(s) so all 40 animals can eat at once — aim for one trough place per head when feed is restricted, to stop bullying and uneven growth.
Space-per-animal depends on species, body size and feeding system. With ad-lib feeding you can share more animals per place; with restricted/once-a-day feeding, give every animal its own space.
Feeding space — key facts
- Total space
- animals × space each
- Feeders needed
- total ÷ feeder length (round up)
- Animals per feeder
- feeder ÷ space each (round down)
- Dairy cow
- ≈ 60–75 cm at manger
- Sheep / goat
- ≈ 30–45 cm each
- Why it matters
- all eat at once, even intake
- Same for water
- use space at the drinker

A place at the trough for every animal
When feed is rationed or fed once a day, every animal must be able to reach the trough at the same time — or the timid ones lose out, intake turns uneven, and growth and milk suffer. The fix is simple linear space: multiply the group by the space each needs, then size the feeder line to match. Too little space breeds competition and injury; the right space lets the whole group settle and eat.
This tool returns the total trough space, the feeders needed and the animals one feeder serves from the group size, space per animal and feeder length — rounding feeders up and animals per feeder down so the answer is buildable. Use it for mangers, feed bunks, water troughs and poultry drinker lines alike. Pair it with the Brooding Temperature and Cost of Gain tools to plan the full setup.
Stop bullying at the bunk
Enough length for every animal to eat at once.
Buy the right number
Feeders rounded up to whole, buildable units.
Even out intake
No timid animal pushed off restricted feed.
Feed or water
Same maths sizes drinker lines too.
Frequently Asked Questions
How is feeding space worked out?+
First the tool totals the space the group needs: total space = number of animals × space each. Then it sizes the line: feeders needed = total space ÷ feeder length, rounded up to a whole feeder. So 40 animals at 30 cm each need 1,200 cm of space; with 240 cm feeders that is 1,200 ÷ 240 = 5 feeders.
How many animals can share one feeder?+
The tool divides the feeder length by the space each animal needs and rounds down: animals per feeder = feeder length ÷ space each. A 240 cm feeder at 30 cm per animal serves 8 animals at once. Rounding down means nobody is squeezed out of a place at the trough.
Why does feeding space matter?+
Too little trough length means timid animals get pushed off feed, intake becomes uneven, and the slowest fall behind in growth or milk. Adequate space lets the whole group eat at once, which is especially important on rationed or once-a-day feeding. Generous space also cuts aggression and injury at the bunk.
How much space does each animal need?+
It varies by species and size — dairy cows often need 60–75 cm at the manger, growing cattle 40–60 cm, sheep and goats 30–45 cm, and poultry only a few centimetres per bird. Enter the figure for your stock; the tool does the rest. Ad-lib feeding can use less space than restricted feeding, where all must eat together.
Is it the same for feeders and drinkers?+
The geometry is identical — total demand divided by the length of one unit — so the same tool sizes a water trough or a drinker line. Just enter the space each animal needs at water rather than at feed, which is usually smaller. Water access still matters: too few drinkers limits intake and, in dairy, milk.
Does it round up the feeders?+
Yes. Feeders needed is always rounded up to the next whole feeder, because a partial feeder cannot serve a fraction of the line — you have to install the whole thing. That is why 1,250 cm of demand over 240 cm feeders gives 6 feeders, not 5.2. Animals per feeder rounds down for the same practical reason.
Can I use it for poultry?+
Absolutely. Poultry feeders and drinkers are sized exactly the same way, with a small per-bird allowance — for example a few centimetres of pan or trough edge per bird. Enter your birds, the space per bird and the feeder length, and the tool gives the number of feeders or drinker lines to install.
What units does it use?+
Space and feeder length are in centimetres, which keeps the arithmetic simple and matches most husbandry guidelines. If your figures are in metres, multiply by 100 before entering them. The outputs — total space in cm, feeders needed and animals per feeder — read straight off.
