How Often Should Metabolic Testing Be Done for Dairy Cows?
Regular metabolic testing is crucial for maintaining the health and productivity of dairy cows. It helps in early detection of metabolic imbalances and allows for timely intervention.
Recommended Frequency of Metabolic Testing
- Transition Period: Test cows 2-3 weeks before calving and again 3-14 days after calving to monitor critical metabolic changes. Samples to assess hypocalcemia should be taken 24-72hrs post calving. Many cows have low blood calcium levels within 24hrs of calving, but it is the cows ability to return to normal blood calcium levels at 72hrs post calving which is the most significant indicator of subclinical hypocalcemia in the herd
- Early Lactation: Conduct tests during the first 2-4 weeks of lactation to assess energy balance and detect issues like ketosis.
- Regular Monitoring: For high-producing herds, periodic testing every 3-4 months can help maintain optimal health and productivity.
Benefits of Regular Testing
- Early Detection: Identifies subclinical metabolic disorders before they manifest clinically.
- Nutritional Management: Provides insights into the effectiveness of feeding programs and allows for necessary adjustments.
- Health Monitoring: Helps in maintaining overall herd health and optimising milk production.
Key Indicators to Monitor
- Energy Metabolism: NEFA, BHB, (and glucose) levels.
- Protein Metabolism: Blood urea nitrogen (BUN) and total protein.
- Mineral Balance: Calcium, phosphorus, and magnesium levels.
- Liver Function: Liver enzymes (AST, GGT).
