See how many kilos of feed the batch consumes per kilo of live weight gained, and what that costs.
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.
Feed cost per kg of live weight for conversions of 1.6 to 2.0; the highlighted bar is yours.
Cost per kg live weight for feed prices of R$ 1.00 to R$ 2.50; the point is your price.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Feed cost per kilo of live weight for conversions of 1.6 to 2.0 and different feed prices.
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 birds housed, the batch mortality, the initial and final average weights, the feed consumed in the cycle, and the feed price. The calculator shows the conversion, the live weight gain, and the feed cost per live kilo.
20,000 birds housed, 4% mortality, initial weight of 0.045 kg and final weight of 2.5 kg, 81,000 kg of feed and a price of R$ 1.60 per kg.
Live birds = 20,000 × 0.96 = 19,200. Gain = 19,200 × 2.5 − 20,000 × 0.045 = 48,000 − 900 = 47,100 kg. Conversion = 81,000 ÷ 47,100 = 1.72. Cost per kg live weight = 1.72 × 1.60 = R$ 2.75.
Because it is the weight sold. The calculation uses the batch's live weight gain, minus dead birds, and not the weight of a single bird.
No. Deduct the leftovers that stayed in the silo or along the feed line. Without that weighing, the conversion comes out optimistic.
High mortality, poorly stored feed, excess heat, and density above the adequate level. Each one increases the feed per kg gained.
Yes, as a starting point. Adjust for the line, the season and the health history.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods.
