See how many birds fit per square meter and how many kilos of live weight that represents.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
Load in kg/m² for densities of 8 to 18 birds/m², with the flock's average weight; the highlighted bar is yours.
Kilos of live weight per square meter at different average weights; the dot is your batch.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Live weight load, in kg per m², for different densities, with the average weight entered.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Enter the number of birds housed, the average weight, the usable floor area, and, if you wish, the target density of your system. The calculator shows the density in birds and in kilos per square meter and the area needed for the target.
20,000 birds, average weight of 2.4 kg, 1,200 m² of usable area and target density of 16 birds/m².
Density = 20,000 ÷ 1,200 = 16.7 birds/m². Live weight = 20,000 × 2.4 ÷ 1,200 = 40 kg/m². Area for the target = 20,000 ÷ 16 = 1,250 m².
It depends on the system, the certification, and the region. Check the current legislation and the requirements of the integrator or the certifier.
Because live weight load is what puts pressure on ventilation, litter and welfare. Two farms with the same number of birds can have very different loads.
No. Use the usable rearing area. Including corridors or fixed areas makes the density look lower than it is.
Yes, starting from the target density. For this, the reverse calculation gives the area needed for the batch's number of birds.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor. Material and fuel properties vary: check with the manufacturer or with analyses of your process before deciding. By using the site, you agree to the Terms of Use.
