5 months until breeding

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.

Revisa tus puntos de control

Desde el destete hasta la cría, es importante vigilar de cerca los puntos de control. Cada objetivo para Age at First Parg (AFC) tiene sus propias medidas. Aquí una descripción general de los puntos de control (Tabla 1) para un rebaño de vacas con un peso corporal maduro (MBW) de 700 kg. Este es un peso corporal normal para las vacas frisonas Holstein.

Otras razas de vacas tienen un peso corporal maduro diferente (Tabla 2). Esta tabla está establecida para una edad en el primer parto de 23 meses, para diferentes pesos corporales maduros:
