Overview used equations in the gross margin analysis.

Description	Equation
Total feed used by delivered animals (kg)	$\left(\frac{\text{Cycle duration}\cdot FCR\cdot ADG}{\text{1,000}}\right)\cdot \text{number of broilers slaughtered}$
Total revenue	$\text{Meanweight}\cdot \text{number of animals slaughtered}\cdot \text{producer price}$
Total feed costs	$\begin{array}{l}\left(\text{Total feed used by delivered animals}\cdot \text{feed price per kg}\right)+\hfill \\ \left(\frac{\left(\frac{\text{Cycle duration}\cdot FCR\cdot ADG}{\text{1,000}}\right)\cdot \left(\text{number of animals slaughtered}-\text{number of animals at set}-\text{up}\right)}{\text{2}}\cdot \text{feed price per kg}\right)\hfill \end{array}$
Total costs day-old chicks	$\begin{array}{l}\text{Number of day}-\text{old chicks at set}-\text{up}\cdot \text{day}-\text{old chick price}\\ \text{Total revenue}-\text{total feed costs}-\text{total costs day}-\text{old chicks}\end{array}$
Total feed profit	$\text{Total revenue}-\text{total feed costs}-\text{total costs day}-\text{old chicks}$
Total other variable costs	$\text{Number of day}-\text{old chicks at set}-\text{up}\cdot \text{other variable costs per day}-\text{old chick}$
Gross margin	$\text{Total revenue}-\text{total feed costs}-\text{total costs day}-\text{old chicks}-\text{total other variable costs}$
Gross margin per 10,000 animals at set-up	$\frac{\text{Gross margin}}{\text{Number of day}-\text{old chicks at set}-\text{up}}\cdot 10,000\text{day}-\text{old chicks at set}-\text{up}$
