A healthy heifer is the future of the herd. Practical information on growth targets, the right time to breed and first calving.
A heifer is a young female bovine that has not yet calved, and she represents the future of your herd. Raising a heifer correctly lays the foundation for a productive, long-lived cow. Poor rearing, by contrast, can lead to a late or difficult first calving and low lifetime production.
The aim is to achieve steady weight gain without allowing the heifer to become either overconditioned or underweight. Overfeeding can cause fat deposition in mammary tissue and reduce future milk production, while underfeeding delays growth.
A heifer should be bred according to her weight and development, rather than calendar age alone. The generally accepted approach is to breed her when she reaches approximately 60โ65% of her mature body weight. Although this varies by breed, it often corresponds to an age of about 13โ15 months and a live weight of about 370โ400 kg.
Target weight varies by breed (local, crossbred, Holstein, etc.). Consult a veterinarian or animal scientist about the appropriate weight and age for your herd.
If breeding takes place at about 14 months, a pregnancy of about 9 months results in first calving at approximately 24 months. This is considered ideal for most farms: very late calving (for example, at 30+ months) means feeding the heifer without a return and increases costs, while calving too early or at too small a size can lead to difficult calving and development problems.
After weaning, a heifer should be raised on a balanced ration based primarily on good-quality forage. Protein and energy should be appropriate for her growth stage, while excessive concentrate feeding and overconditioning should be avoided. Unrestricted access to clean water is essential.
Heifers should be included in the herd's vaccination schedule (foot-and-mouth disease, brucellosis, etc.) and parasite-control program. The brucellosis vaccine in particular is given to female calves within a specific age range, so age tracking is important.
You cannot identify the right breeding time without knowing whether the heifer has reached her target weight. Recording her date of birth, interim weights and vaccinations provides clear answers to questions such as "Which heifer is ready to breed?" and "Which one is due for vaccination?"
