See how many kilos of dry matter the batch eats per kilo 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.
Kg of dry matter per kg gained for gains of 0.8 to 1.6 kg/day; the highlighted bar is yours.
Feed cost per kg gained at different dry matter prices; the point is yours.
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 kg of weight gained for different daily gains and dry matter prices, with the intake 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 dry matter intake per animal per day, the average daily gain, the cycle length, the number of animals in the batch, and the price of the diet's dry matter. The calculator shows the conversion, the total feed for the batch, and the cost per kg gained.
Intake of 8.4 kg MS/day, gain of 1.2 kg/day, 120 days, 100 animals and MS at R$ 0.89.
Conversion = 8.4 ÷ 1.2 = 7.00 kg MS/kg. Lot feed = 8.4 × 120 × 100 ÷ 1,000 = 100.8 t of DM. Gain = 1.2 × 120 × 100 = 14,400 kg. Cost per kg = 7.00 × 0.89 = R$ 6.23.
Depends on the category, diet and gain. Lower values are better. Compare your lot with the farm's own history and with the nutritionist's target.
Because conversion on an as-fed basis depends on the diet's moisture. On a dry matter basis, the comparison between batches and diets is fair.
Yes, using the batch average for the period. If the batch has mixed categories, separate the calculations.
It turns feed conversion into cost. With the same intake, a diet that is more expensive per kg of DM can have a higher cost per kg of gain, even with good conversion.
