1. Heifer Management Overview Based on PennState Extension Circular 385

2. Introduction Dairy replacements are the foundation of any dairy enterprise. Proper genetics, breeding, feeding, and health management improve herd productivity. This presentation outlines key practices for raising healthy dairy heifers.

3. Genetics and Breeding • Selecting superior bulls based on Predicted Transmitting Ability (PTA). • Importance of Artificial Insemination (AI) over natural service. • Avoiding genetic defects like mulefoot and DUMPS. • Maintaining accurate records for breeding and herd improvement.

4. Feeding Strategies • Colostrum feeding is crucial in the first hours after birth. • Balanced diet with proper protein, energy, and vitamins. • Transition from milk to solid feed after weaning. • Pasture management and grain supplementation for older heifers.

5. Health Management • Vaccination against brucellosis, IBR, PI3, and BVD. • Preventing calf scours and respiratory infections. • Parasite control for both internal and external parasites. • Regular health check-ups and biosecurity measures.

6. Housing and Biosecurity • Individual calf hutches or well-ventilated barns. • Clean, dry, and well-bedded pens. • Avoid overcrowding to reduce disease spread. • Maintain proper ventilation and temperature control.

7. Cost Considerations • Feeding accounts for over 50% of raising costs. • Balancing feed costs while maintaining growth. • Contract heifer raising as an alternative strategy. • Reducing culling rates through effective management.

8. Conclusion • Raising heifers requires a combination of good genetics, feeding, and management. • Proper health care and housing are essential for reducing mortality. • Cost control and efficient resource utilization improve farm profitability. • Implementing best practices ensures a productive and sustainable dairy operation.
