Heifers: Big girls XL
The 2009 ADHIS data showed that many Australian herds would benefit from better grown out heifers. Heifers are not realising their full potential for milk production and are calving later.
On most dairy farms the heifers won't cover their rearing costs until they reach their second lactation. If they don't get there they still owe you money when they are culled.
Having a feed plan for your heifers is as important as it is for your milkers.
Heifers need high-quality supplements for at least 6 months of the year.
- Critical times for feeding supplements are post weaning and when there is a shortage of quality pasture (this is usually for at least 6 months of the year in most Australian dairy regions).
- Use high-quality supplements containing at least 11.5 MJ ME/kg dry matter and 16% crude protein.
- You'll probably need a cereal plus a legume.

Weighing heifers is the best way to keep track of their progress.
Use the Growth Target Rule of Thumb to work out the target weight for your heifers.
Growth Target Rule of Thumb
Assume all your calves are the same age as the oldest in the group, as they will all be mated at the same time.
Holstein-Friesian target weight (kg) = age (months) x 20 + 40
Jersey target weight (kg) = age (months) x 15 + 35 |
Draft as you weigh and then preferentially feed heifers below the target weight.
For more information:
Use the reminder card to work out the target weight for your heifers and pin it up in the dairy.
Wither height and girth weight charts
If you don't have scales you can use a girth tape or wither height measuring stick available from rural merchandisers.
Check the wither height and girth tape charts and wither height table.
Rearing heifers off farm
You may decide to rear your heifers off farm. To make sure that both parties are clear about the expectations and responsibilities document these in an agreement or contract.
Here is an example contract that shows the information to include in contract or agreement.
