What is one major cause of decreased milk production in dairy cows?

Mastitis is a significant cause of decreased milk production in dairy cows because it is an infection of the udder tissue that leads to inflammation. When a cow develops mastitis, it can result in pain and discomfort that makes it difficult for her to milk properly. The infection can also lead to a reduction in the quality and quantity of the milk produced. In some cases, the milk may become unsuitable for human consumption due to elevated somatic cell counts, which are indicative of infection and inflammation.

While factors such as lack of water, low-quality feed, and high environmental temperature can also impact milk production, mastitis is particularly concerning because it directly affects both the health of the cow and the quality of the milk she produces. Consequently, effective management practices, monitoring for signs of mastitis, and prompt treatment are essential in maintaining optimal milk production in dairy cows.
