Fat Cow Syndrome/Fatty liver disease

                     Fat Cow Syndrome




A nutritional disease of ruminants, fat cow syndrome often occurs as the result of over-conditioning during the late lactation and dry periods. Cows with fat cow syndrome are often first noticed when seen standing amongst other dry cows.


CAUSE OF FAT COW SYNDROME

Also referred to as fatty liver disease, the cause of fat cow syndrome has not been established, but it is believed to develop due to faulty feed management methods that allow for an excessive consumption of unbalanced diets. Progression of the disease occurs in obese cattle before and during parturition.

Disease development is considered to be associated with:

Endocrine changes that occur:After calving with the onset of the production of milk Time  and when feed intake is decreased.

SIGNS OF FATTY LIVER DISEASE

The syndrome has no unique clinical signs, but one distinctive indication is an overly fat cow. Other disease characteristics include, for example, the presence of:

Inappetence

Depression

Lowered milk production

Excessive loss of body condition

Progressive debilitation

Weakness

Nervous

Elevation in temperature

Reduced fertility and poor reproductive performance

Greater incidences of:

Milk fever

Ketosis

Clinical mastitis

Retained fetal membranes

Blood test results that show elevated levels of nonesterified fatty acid concentrations (NEFA) and increased ketones.

DIAGNOSIS OF FAT COW SYNDROME

The signs and symptoms of the disease resemble other diseases, causing fatty cow syndrome to often be misdiagnosed. Diagnosis is usually made when the cow:

Is observed to be off feed

Has died, usually as the result of a different complication.

TREATMENT OF FAT COW SYNDROME

There is no proven treatment for the disease. While there are methods to treat similar diseases in nonruminants, they have not been proven effective in cattle. Steps to take to treat the animal include providing good supportive care and feeding the animal a balanced diet, such as:

High-quality hay with little or no grain in the early stages of the drying-off period

A vitamin and mineral supplement to fulfill nutritional requirements for:

Protein

Energy

Calcium

Phosphorus

Selenium

No high-calcium grain mixes until after calving.

PREVENTION OF FATTY LIVER DISEASE IN COWS

To reduce the incidence of fat cow syndrome, it is recommended to avoid:

Over-conditioning cows by establishing herd management methods to ensure that cows maintain the correct body condition. The ideal body condition score when at calving stage is 2.5 to 3. When drying off, cows should be at this score, and weight should be maintained throughout the dry period

Rapid diet changes

Unpalatable feedstuffs

Environmental stress by minimizing changes that could increase stress. For example , stay clear from making changes to:

Feed rations

Herd mates

Housing

Temperature.

This disease can have an economic impact on a farm. The syndrome not only affects milk production, but the animals often suffer from various metabolic and infectious diseases. Animals that develop fatty liver often end up culled from the herd.
