How does mastitis affect the economy?

The reduction in milk production due to mastitis was the main component of the economic impact (54.9%). The culling of cows with chronic infection was associated with an increase in the economic impact of mastitis and a reduction in the average productivity per cow.

Why does mastitis cause such a large impact in the dairy industry?

Mastitis reduces milk production and milk quality. Mastitis causing pathogens include bacteria (mostly Staphylococcus aureus, coagulase-negative staphylococcus, Streptococcus uberis, Streptococcus dyslactiae, Streptococcus agalactiae, enterococci and coliform bacteria including Escherichia coli) and Mycoplasmas.

What are the losses due to mastitis?

Mastitis losses are due to reduced milk production, cost of treatments, and culling, accounting for 78%, 8%, and 14%, respectively (7).

How does mastitis affect production?

Mastitis reduces milk yield and degrades milk quality, diminishing the dairy industry's ability to compete in international markets. Together, these factors erode the milk income received by farmers.

What is the importance of mastitis?

Mastitis is one of the most prevalent and costly diseases within the dairy industry, impacting both cows' health and milk quality. Awareness of the disease and its economic impact can increase motivations for change. Prevention of mastitis is key to management of the disease.

What is the history of mastitis?

The first whole UK approach to controlling mastitis began in the 1960s. Research done by the National Institute for Research in Dairying at the University of Reading resulted in the 5 point plan, which was aimed at the control of contagious mastitis spread between cows during milking.

What causes mastitis in dairy cattle?

Mastitis in dairy cows is caused by udder infections, usually resulting from bacteria introduced either during the milking process or from environmental contact. Examples include contamination from milking equipment, milking personnel, manure contamination or dirty stalls.

How does mastitis affect milk production in cows?

Toxins released by mastitis bacteria damage milk-secreting tissue and ducts throughout the mammary gland, reducing milk yield and quality. Mastitis can occur at any stage of lactation, including the dry period, but is most likely in the first month after calving and in late lactation.

What causes mastitis in dairy cows?

Mastitis occurs when white blood cells (leukocytes) are released into the mammary gland, usually in response to bacteria invading the teat canal or occasionally by chemical, mechanical, or thermal trauma on the udder.

What is the economic loss from mastitis in the US each year?

Total annual economic losses to dairymen in the United States attributable to mastitis have been estimated at $400 to $500 million, or $23 per cow.

Can mastitis cause infertility?

Mastitis (intramammary infection) causes the deterioration of ovarian follicular responses in cows, resulting in low fertility.

What is clinical mastitis?

Clinical mastitis is an inflammatory response to infection causing visibly abnormal milk (eg, color, fibrin clots). As the extent of the inflammation increases, changes in the udder (swelling, heat, pain, redness) may also be apparent. Clinical cases that include only local signs are referred to as mild or moderate.

What is mastitis in livestock?

Bovine mastitis is an inflammatory response of the udder tissue in the mammary gland caused due to physical trauma or microorganism infections. It is considered the most common disease leading to economic loss in dairy industries due to reduced yield and poor quality of milk [1].

What is environmental mastitis?

Environmental mastitis is an intra-mammary infection of the udder originating from bacteria in the cow's environment. Some common bacteria found in the cow's environment which can cause mastitis include, Streptococcus uberis, Escheria coli and Klebsiella.

Can mastitis lead to death?

If mastitis progresses untreated, abscesses can develop. Abscesses require immediate treatment, which can involve aspiration or surgical drainage. In rare cases, untreated mastitis may cause sepsis. Sepsis is the body's extreme reaction to infection, and it can result in organ failure and even death.
