List each cow once on the Cows tab — name or tag, breed, status (milking, dry, in-calf) — and her total litres and milk income roll up. Each day, per cow, enter the morning and evening litres, how much you sold and the price per litre on the Milk Records tab. The day's total and sale value are worked out for you.
The Dashboard shows litres today and this month, milk income this month, and your average litres per milking cow — the yield figure that tells you which cows earn their feed. Set today's date to keep it current. Yellow cells for typing; the rest is locked. Opens in Excel or Google Sheets — record each milking at the shed on your phone.
