Negative Energy Balance (NEB) is a common occurrence affecng at least 80% of dairy cows. NEB is a result of insufficient energy intake (usually caused by a depression of appetite) relative to requirements resulting in lipolysis, and to some extent, proteolysis to compensate for the energy deficit. High producing dairy cows need to mobilize body reserve to be able to sustain their milk production. In early lactation, until energy intake assures the requirements, dairy cows, especially high producing breeds, enter a state of negative energy balance (NEB), losing high amounts of body condition. Modern high-yielding dairy cows enter a state of negative energy balance (NEB) around calving when the energy demand for maintenance and lactation exceeds that of dietary energy intake. Cows with excessive body tissue mobilization at this stage may take up to 20 weeks to regain a positive energy balance status.


NEB is believed to have an influence on several productions and physiological parameters in dairy cows. It would, therefore, be of paramount importance to identify animals at risk of this condition and take mitigating action.

Dairy cows in negative energy balance have an increased risk to develop clinical or sub-clinical ketosis. Ketosis in dairy cows will have a negative impact on dry matter intake, health, fertility, and production of the lactating cow.

Metabolic changes in cows associated with the onset of Negative Energy Balance appear to be the most responsible factors for the coordinated detrimental effects on metabolic health and reproductive performance. Negative energy balance during early lactation is related to decreasing feed intake prepartum and provides the major nutritional link to low fertility in lactating dairy cows. Finally, negative energy balance delays early ovulation and recovery of postpartum reproductive function and exerts carryover effects (Body Condition Scores, oocytes, uterus) that reduce fertility during the breeding period.
