Production is yearly average across a full lactation — actual output peaks 6–10 weeks in-milk and tapers to dry-off. Milk pounds (not gallons) is the industry standard: a gallon of cow milk weighs 8.6 lb; sheep milk is heavier at 8.5 and fattier.
Cheese yield varies by style. Fresh cheeses return 15–20% of milk weight; hard cheeses drop to 8–11%. Butter yield tracks butterfat directly — Jersey and sheep milk make more butter per gallon than Holstein.
annual_gal = head × gal_per_day × lactation_days × (1 + seasonal)
annual_lb = annual_gal × lb_per_gallon
butter_lb = annual_lb × fat_pct × 0.82
