Negative Energy Balance (NEB) is one of the most underestimated health challenges in modern dairy cow management. Occurring primarily in early lactation, NEB can lead to (sub)clinical ketosis, reduced milk yield, and increased risk of secondary disorders such as displaced abomasum and metritis. The economic impact is significant, yet often hidden. Detecting NEB early and reacting promptly is critical—not only to safeguard cow health and welfare but also to protect farm profitability. Proactive monitoring and timely intervention can prevent costly complications and keep your herd performing at its best.
Cows suffering from (sub)clinical ketosis due to negative energy balance can now be treated without human intervention. When MilkGenius detects a risk, it triggers BouMatic’s liquid feed dispenser system to deliver extra energy supplements directly to the cow’s feeding trough.
MilkGenius now brings farmers a powerful combination: automated NEB treatment and intelligent mastitis detection. Together, these groundbreaking features form a strong tool to safeguard herd health and improve productivity. Discover how the new mastitis detection function can make a real difference for your farm
Nearly every dairy cow experiences a Negative Energy Balance (NEB) around calving. It occurs when the energy required for milk production and maintenance exceeds the energy intake from feed. In some cases NEB causes sub-clinical ketosis, which is difficult to detect because your cow doesn’t show obvious clinical signs. But the condition can have several significant impacts:
Decreased milk production in the early lactation. This drop in production and thus not reaching the production peak will also affect the production in the rest of the lactation.
Health problems and decreased immunity: cows are more susceptible to metabolic disorders such as clinical ketosis and fatty liver disease, which can further compromise their health. The weakened immune system increases the risk of other illnesses and infections such as leg problems, mastitis, displaced abomasum, etc.
Increased veterinary costs for consults and treatments.
Poor fertility: sub-clinical ketosis can lead to reduced reproductive performance, making it harder for cows to conceive and maintain pregnancies.
Scientific research has proven that sub-clinical ketosis can result in a total cost of up to €262 per affected cow*, which can result to an even higher total cost than cost associated with mastitis. Another study** indicated that sub-clinical ketosis ranks as the number one disease globally in terms of annual losses, costing approximately USD 18 billion each year.
Managing NEB effectively is crucial for maintaining the health, productivity, and profitability of dairy herds. Knowing the ratio of fat-to-protein promotes early detection of sub-clinical ketosis. Ensuring a balanced diet at the right time with adequate energy intake can help mitigate these negative effects.
