In dairy cows, an abrupt increase in milk production after calving imposes high metabolic and thus nutritional requirements on the cow. When dry matter intake does not meet increased energy requirements, a status of negative energy balance (NEB) develops.
Metabolic profile | Metabolic and high level functional changes | Endocrine changes | Functional changes |
---|---|---|---|
Negative Energy Balance | Impaired synthesis and secretion GnRH and LH |
|
|
Emergency energy production from adipose tissue and proteins |
|

Increased Metabolic Rates | Increased metabolism of oestradiol and progesterone in the liver |
