E165 Ketosis: The Silent Threat to Dairy Herd Success

Key Points: 1. Ketosis affects up to 40% of fresh cows, costing farmers $289 per case. 2. For a 100-cow herd, annual losses can range from $5,800 to $11,560. 3. Ketosis occurs when fresh cows can’t get enough energy from feed, forcing them to break down body fat. 4. Subclinical ketosis is often undetected but still impacts milk production and cow health.Detection Methods: 1. Blood testing (BHB levels) 2. Milk testing through DHI services 3. Urine ketone strips 4. Activity monitoring systemsEconomic Impact: • Costs are 50% higher for older cows compared to first-calf heifers. • Ketotic cows are 4.3 times less likely to get pregnant on first breeding. • High-risk operations could lose up to $7,606.87 annually from ketosis-related issues.Treatment Options: • Mild to moderate cases: 300ml propylene glycol once daily for 3-5 days. • Severe cases: IV dextrose treatment (500ml of 50% dextrose) followed by propylene glycol. • Vitamin B12 shots: 1.25 to 5mg per cow daily for 3-5 days. • Temporarily reducing milking frequency can aid recovery.Success Stories: • A 1,000-cow dairy in Wisconsin reduced ketosis rates by 5%, saving $14,500 in the first year. • University of Guelph research on reduced milking frequency showed promising metabolic improvements.Key Takeaways: 1. Early detection and prompt treatment are crucial for managing ketosis. 2. Monitor fresh cows closely, especially in the first week after calving. 3. Develop a solid transition cow program with your veterinarian and nutritionist. 4. Have treatment protocols ready before you need them. 5. Every day of delayed treatment costs money in lost milk production.https://www.thebullvine.com/management/ketosis-the-silent-threat-to-dairy-herd-success/
