How much feed each dozen eggs takes, and what it 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.
How much the feed for each dozen costs at different laying rates, with the price you entered.
How the cost per dozen follows the feed price, with the lay rate entered.
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 dozen for combinations of lay rate and intake per bird, with the feed price 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 laying hens, the daily feed intake per bird, the laying rate of the batch, and the price of the feed. The calculator shows how much feed each dozen eggs takes and the cost of that feed.
500 laying hens, intake of 110 g/day per bird, 85% lay rate and feed at R$ 2.50/kg.
Feed per egg = 110 ÷ 0.85 = 129.4 g. Per dozen = 129.4 × 12 = 1.55 kg. Cost = 1.55 × 2.50 = R$ 3.88.
The batch lays 425 eggs per day and consumes 55 kg of feed per day.
Because the bird eats almost the same amount and lays less. So each egg takes more feed.
It is only the feed cost. The total cost includes birds, labor and facilities, and must be added up to compare with the market.
