Well grown heifers
- Have improved milk production
Heifers reaching target liveweight will produce 8.5kgMS more in their first lactation than if they are 10% below target liveweight. - Have greater lifetime productivity
Heifers reaching target liveweight will have 5% better 6wk in-calf rates and 1.5% lower empty rates. This equates to $35 economic benefit per heifer compared to heifers 10% below target liveweight. - Have reduced replacement costs
Using InCalf data for a mob of 50 heifers, the potential gain to move them from 10% under target liveweight to achieving targets is $3875 at a $5/kgMS milk price.
This section highlights some of the key aspects to rearing heifers from weaning through to first calving. It will help you choose a heifer replacement strategy, set relevant growth targets, monitor performance and manage relationships.

Heifer growth should be measured by liveweight, the only objective measure of dairy heifer performance. Weight performance is also useful to inform working relationships between stock owners and the heifer grazier.
