Key livestock formulas
| Feed Requirement | daily feed = body weight × intake % × (1 + wastage) |
|---|---|
| Feed Conversion Ratio | FCR = feed consumed ÷ weight gained |
| Animal Weight | weight (lb) = girth² × length ÷ species constant |
| Livestock Water | daily litres = animals × per-animal need × weather factor |
| Stocking Rate | stocking rate = total livestock units ÷ hectares |
| Pasture Requirement | hectares = daily demand ÷ (pasture growth × utilisation) |
| Feed Cost | cost = Σ (kg per day × price per kg) × (1 + wastage) |
| Average Daily Gain | ADG = (current weight − start weight) ÷ days |
