Costs per kilogram of milk
Ensuring that the calf benefits from a good-quality rearing period will ensure healthy animals in the future that produce the best possible yield.
Calculations show that:
1. Calf housing represents only 0.6% of the total cost of milk (0.22/34.5 EUR cents)
2. Calf housing represents only 4% of the total rearing costs (€2,000/€48,000).
- 100 dairy cows, with 9,000 kg of milk per cow
- 60 youngstock animals, with calving age at 24 months
- 30% replacement
- Depreciation of calf housing: 15 years
- 10% annual costs (7% depreciation, 3% interest on total amount invested)
Basic principles of calculation
- 105 calves born annually, of which 100 live births.
- Keep 30 calves for replacement, housed in igloos (up to 3 weeks) and
- in group igloos (up to 12 weeks)
- Keep 70 calves for fattening, housed in igloos (up to 3 weeks)
- The following is required: 15 igloos and 3 group igloos
- 15 igloos with accessories (costing €500) €7,500
- 3 group igloos with accessories (costing €2,500) €7,500
- Lay concrete paving in farmyard (150 m2 at €30 per square metre) €4,500
- Rainwater drainage €500
Total investment: €20,000
Interest and depreciation per annum: 10% = €2,000
At an annual milk production of 900,000 kilograms, this is: €0.222 per 100 kg of milk, i.e. 0.22 EUR cent per kilogram of milk,
despite the farm's total annual rearing costs being around €48,000 (30 heifers x €1,600 per heifer)
