Milk fever is a metabolic disorder caused by insufficient calcium, commonly occurring around calving.
Milk fever, or hypocalcaemia, is when the dairy cow has lowered levels of blood calcium.
Milk fever generally occurs within the first 24 hours post-calving, but can still occur two to three days post-calving. It can be either clinical or subclinical.
Clinical milk fever includes both “downer” and “non-downer” cows with less than 1.4mM blood calcium.
Milk fever increases the risk of other metabolic diseases and infections, such as ketosis and metritis, and approximately 5 percent of downer cows do not recover.
Sub-clinical milk fever includes cows with less than 2.0mM but more than 1.4mM blood calcium.
Milk fever, or hypocalcemia, has been a problem of fresh cows for over two centuries.
Effective nutritional management during the dry period and early lactation has decreased clinical cases of milk fever to rates lower than 1 percent.
On the other hand, subclinical cases have been reported to affect as many as 73 percent of animals of third and greater lactation.
Milk fever cases should be treated with 500 milliliters of 23 percent calcium gluconate IV and followed by the administration of two oral calcium bolus given 12 hours apart.
It is important to emphasize that oral calcium bolus should not be administered if cows do not respond to the calcium IV treatment
