How Much Does It Cost to Rear a Calf?
Calf rearing is one of the highest-cost periods in a beef or dairy enterprise — and one of the most variable. Whether you're running a replacer system or feeding whole milk, knowing your true cost per calf is the starting point for improving margin across the herd.
Quick answer
Rearing a calf to weaning typically costs £200–£450 all-in. Feed costs alone (milk + concentrate) are usually £100–£220 depending on system and days to weaning. Labour and overheads add another £100–£240 depending on your setup.

Why labour costs vary so much
Labour is often the most undercosted item in calf rearing budgets. Farms running individual pens with twice-daily feeding and manual recording can easily spend 15–20 hours per calf to weaning. Automated calf feeders reduce that to 3–6 hours per calf — a significant saving on large batches. Always cost labour at a real replacement rate, not zero, even if it's family labour.
Whole milk vs replacer: the real comparison
The cheapest option depends on your farmgate milk price. At current prices (30–35p/L), 7 litres of whole milk per day costs £2.10–£2.45/day. Quality milk replacer at 750g/day costs approximately £1.35–£1.60/day. Over 70 days, replacer saves £35–£60 per calf in direct feed cost — but whole milk can support faster early live weight gain in high-BCS systems. If your milk price rises above 40p/L the replacer case strengthens further.
