How much each kilo gained costs for the batch, and how much feed conversion weighs in that calculation.
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.
Share of each cost in the price per kilo gained.
How much the cost of the kilo gained rises when the feed price changes.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Cost per kilo gained for combinations of CA and feed price, with the other costs per animal and the weight gain 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 animals' initial and final weights, the days of rearing, the feed consumed per animal, the feed price, and the other costs per animal. The calculator shows the feed conversion and the cost per kilo gained.
Initial weight of 25 kg and final weight of 110 kg in 90 days; 245 kg of feed per animal at R$ 1.40/kg; other costs of R$ 25 per animal.
Gain = 110 − 25 = 85 kg. CA = 245 ÷ 85 = 2.88. Average gain = 0.94 kg/day.
Feed = 245 × 1.40 = R$ 343; total = R$ 368. Cost per kg gained = 368 ÷ 85 = R$ 4.33.
It depends on the phase, the genetics, and the diet. Compare with your system's history and with the reference for each phase.
Because feed is usually the largest part of the cost. Each extra 0.1 of CA increases the cost per kilo gained.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods.
