What is milk fever?

Milk fever is most commonly found in dairy cows and is a metabolic disease that is caused by low calcium blood levels. Milk fever can lead to a shortened life span and reduced milk production with one in twenty cows suffering from milk fever dying.

Signs of a case of clinical milk fever can develop rapidly within 2-4 hours and if left unaided, the cow could potentially die within 10-24 hours. 

Subclinical milk fever occurs when calcium levels appear below 'normal' and may not show extreme indicators of milk fever. Typically, a cow with subclinical milk fever will see a drop in milk yield, poor weight gain and poor conception rates. Subclinical milk fever can often develop into clinical milk fever. 

Why Does Milk Fever Occur?

The onset of lactation causes a sudden and large demand of calcium requiring an extra 

80g per day from the cow. The cow can adapt to this demand by:

• Drawing on her own reserves from bone and tissue

• By improving absorption from the diet 

• By reducing losses in urine 

There is a balance between lactational calcium demands and the ability of a cow to mobilise her own calcium reserves to meet this demand. The cows ability to maintain this balance and meet demands will influence on whether or not milk fever will develop. 

Signs: Typical signs of milk fever begin with tremors in the muscles of the head and limbs which then leads to the cow staggering and then eventually going down into a sitting position. Finally if left unaided the cow will collapse into a coma and may potentially die.

Other symptoms can include:

• Dry muzzle

• Staring eyes

• Cold legs and ears

• Constipation

• Drowsiness

Causes: Over 80% of cases of milk fever happen within 24 hours of calving. This is because the production of milk and colostrum drain calcium from the blood of the cow. Some cows are unable to replace the calcium quick enough which is the main cause of milk fever.
