Heifer Rearing

HEIFER REARING

It is of major importance that heifers obtain a successful rearing program. Various studies have shown where farmers have carried out a successful rearing program:

  • Cows remained in the herd for longer (≥ 5 lactations)
  • Cows showed lower incidences of calving problems
  • Cows produced more milk per subsequent lactations

NB. That calving down at 24 months is a main driver of the above points and similarly, nutrition has a major role on achieving this target. Therefore, in order to get heifers calving down at 23 – 24 months of age they need to be growing at certain weights through their life.

Below is a table of what weight heifers should be at different ages up to 24 months of age.

*Target Breakdown:
HF
HF*J
3 month heifer BW (kg) 116 100
3 month heifer BW (kg) 116 100
6 month heifer BW (kg) 175 150
12 month heifer BW (kg) 290 250
15 month heifer BW (kg) @ breeding 350 300
Pre‐Calving BW (kg) approx. 24 months 525 400
Mature BW 580 500
