ARP reference table
The kilos of beef per hectare and per year come from the ranges published by the Asociación Rural del Paraguay for each zone, both on native rangeland and on sown pasture. We use the midpoint of each range.

The numbers every producer needs to run
Stocking rate, fattening, weaning, kilos per hectare, budget, ROI of a cycle and supplementation. Pick the calculator you need: the result updates on its own as you enter your own numbers.
All seven calculators share the same approach: technical reference parameters for Paraguayan cattle ranching, explained below each result. None of them replaces a field survey.
What it can yield
- Production per hectare
- — kg of beef per ha and per year
- Total production
- — kg of beef per year
- Estimated stocking rate
- — cow equivalents per hectare (EV/ha)
- Head it sustains
- — in cow equivalents
- Estimated gross income
- — annual production × price per kilo. Does not deduct costs.
What the batch produces
- Estimated final weight
- — kg per animal, at the end of the days indicated
- Kg gained per animal
- — kg produced per head
- Total batch production
- — kg of live weight gained
- Kg produced per hectare
- — only if you entered the batch area
What you'll wean
- Pregnant cows
- — based on the diagnosed pregnancy rate
- Weaned calves
- — after deducting the pregnancy-to-weaning loss
- Weaning rate
- — calves weaned over mated cows: the indicator that matters most for the profitability of a breeding herd
The indicator that matters most
- Kg of beef per hectare
- — kg/ha/year: the metric that sums up the real efficiency of the ranch
- Where it places you
- —
Reference, using the same ARP table as calculator 01: less than 50 kg/ha/year is unimproved native rangeland; 50 to 130, mixed or moderate pasture; more than 130, sown pasture with good management.
What's left
- Total income
- — kg sold × price
- Total costs
- — sum of the four line items
- Margin
- — income minus costs, before taxes
- Margin per kilo
- — USD per kg sold
- Margin per hectare
- — only if you entered the area
Estimated return
- Estimated final weight
- — kg per head at the end of the cycle
- Total investment
- — cattle purchase + operating costs
- Sale income
- — head × final weight × sale price
- Profit
- — income minus investment
- Cycle ROI
- — profit over investment
- Annualized return
- — the cycle's ROI, brought to an annual basis
This is a simplified estimate, not a financial internal rate of return. It does not include financing, taxes, transport losses or price variation during the cycle.
How much supplement you need
- Per animal, per day
- — kg of supplement (as-fed) per head
- Per batch, per day
- — kg/day for the whole batch
- Total for the gap
- — kg accumulated over the days indicated
- In metric tons
- — to quote the purchase or stockpile
01The assumptions
What numbers the stocking rate calculator is built on
We prefer to show the assumptions rather than sell a precision the tool doesn't have. The other six calculators show their own calculation note below the result.
Cow equivalent
165 kg per cow equivalent per year
A cow equivalent is, according to the ARP, a 400 kg cow that raises a calf to 160 kg at weaning, or a 410 kg steer that gains 500 g per day. That is where the reference annual production per animal comes from.
Mix
Weighting by area
If you enter 60% sown pasture, the result weights 60% of the pasture yield and 40% of the native rangeland yield. It's a simplification: on a real ranch, water, paddock layout and pasture condition all have an effect.
This is a reference estimate, not a project. It does not replace a field survey: real stocking capacity depends on the condition of the pastures, on the watering points, on the paddock layout and on the infrastructure. And one clarification that matters to us: we do not calculate margin or profitability because in Paraguay there is no national reference cost of production per kilo —the ARP itself acknowledges it as a pending task—. The real cost is calculated on the numbers of each establishment.
From the number to the ranch
The fine calculation is done standing in the paddock.
We go to your ranch, survey pastures, watering points and infrastructure, and hand you the report with the real stocking capacity and the three improvements that pay off most.
