Calf Milk Feeding Calculator
Work out the daily whole-milk allowance for a young calf based on its body weight.
Young calves are fed whole milk at about 10% of body weight per day, split into two feeds, alongside clean water and starter feed from week two. Over-feeding milk causes scours; introduce good calf starter early to develop the rumen and allow earlier weaning.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Calf Milk Feeding Calculator
Getting calf feeding right in the first weeks sets up a healthy, productive future animal — and milk fed to calves is milk not sold, so the amount matters financially too. The standard guideline is to feed whole milk at about 10% of the calf's body weight per day, split into two feeds, while introducing clean water and calf starter early to develop the rumen for earlier weaning. This tool gives the daily and per-feed milk allowance from the calf's weight.

Frequently asked questions
How much milk should I feed a calf per day?+
About 10% of its body weight per day for the first weeks — so a 35 kg calf gets roughly 3.5 litres, split into two feeds. Adjust down as starter intake rises toward weaning.
When can I wean a calf off milk?+
When it is reliably eating about 1–1.5 kg of calf starter daily (often around 8–10 weeks). Early starter intake develops the rumen and allows earlier, cheaper weaning without a growth check.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
