Feed a balanced diet to ensure sufficient growth.
Most farmers feed according to a well-designed plan up to the first few weeks after weaning and carefully monitor the results. Once the calf reaches the age of 5 months and the transition to a diet including forage was managed successfully, there is a tendency to feed what is readily available, sometimes without a clear view on the needs of the calf and also to stop monitoring growth and development in a systematic way. After reaching the age of 5 months, a balanced diet should be fed to ensure sufficient growth without excessive fat deposition. A challenge can be to feed enough crude protein.
Check your checkpoints
From weaning to breeding it is important to keep a close eye on the checkpoints. Each goal for Age at First Calving (AFC) has its own measures. Here an overview of checkpoints (Table 1) for a cow-herd with a mature bodyweight (MBW) of 700 kg. This is a normal bodyweight for Holstein Frisian cows.
Other breeds of cows have a different mature body weight (Table 20). This table is set for an Age at first calving of 23 months, for different mature bodyweight:
|Checkpoints @700 kg MBW - Holstein Frisian||AFC 23m||AFC 24m||AFC 25m||AFC 26m|
|Bodyweight at 3 months||126||120||113||106|
|Bodyweight at 6 months||221||209||197||185|
|Bodyweight at 1 year||398||378||357||337|
|Avg. daily gain year 1||975||920||864||808|
|Age at first breeding||13||14||15||16|
|Age at first calving||23||24||25||26|
|Checkpoints @ 23m AFC - Other breeds||700kg MBW||600kg MBW||525kg MBW||450kg MBW|
|Bodyweight at 3 months||126||108||95||81|
|Bodyweight at 6 months||221||190||166||142|
|Bodyweight at 1 year||398||341||298||256|
|Avg. daily gain year 1||975||836||731||627|
|Age at first breeding||13||13||13||13|
|Age at first calving||23||23||23||23|
