Introduction:

The early postpartum period in dairy cows is critical for ensuring long-term health, productivity, and reproductive efficiency. This study aims to explore the effects of reducing milking frequency from three to two times daily during the first ten days post-calving on metabolic status, calcium levels, overall health, and milk yield. Addressing the gap in current research, this study hypothesizes that a temporary reduction in milking frequency can stabilize blood calcium levels, thereby reducing the risk of metabolic disorders such as hypocalcemia, improving appetite, and energy balance.

Methods:

A controlled experiment will be conducted on Holstein cows, selected based on age, parity, and lactation history to ensure a representative sample. Cows will be divided into two groups: the experimental group will be milked twice daily for the first ten days post-calving before transitioning to thrice-daily milking, while the control group will be milked thrice daily throughout. Metabolic health indicators, including blood calcium levels, ketone bodies, and energy balance, will be monitored, alongside milk yield and reproductive health markers.

Expected Results:

It is anticipated that cows in the experimental group will show a more stable metabolic profile, with fewer incidences of hypocalcemia and other metabolic disturbances. This stabilization is expected to lead to improved appetite and energy status, reducing the risk of ketosis and other metabolic disorders. Additionally, the study expects to observe a positive impact on milk yield stability and reproductive health compared to cows milked thrice daily from the onset.

Discussion:

The findings of this study could have significant implications for dairy farming practices, offering a potential strategy to enhance cow health and productivity through management of milking frequency. By demonstrating the benefits of reduced milking frequency on metabolic health and productivity, this research could inform guidelines for post-calving cow management, potentially improving dairy farm sustainability and animal welfare.

Conclusion:

This research aims to contribute to the understanding of how milking frequency affects dairy cows' metabolic health and productivity in the critical post-calving period. By providing evidence-based recommendations, the study seeks to improve dairy management practices, supporting the industry's efforts towards optimizing animal health and productivity.
