Your cow just gave birth to a healthy calf, you are happy, and everything seems to be fine. However, your cow’s udder looks swollen and tight. Is that normal?
It’s a situation that many dairy farmers have encountered before. A dairy cow showing these symptoms might have udder edema, also known as udder swelling. This condition occurs mostly around calving. The good news is that it is not contagious. However, it can have major implications for your cow’s well-being, milk production, and the risk of developing mastitis is higher.

Mammary oedema is a circulatory disorder, unrelated to any infectious agent (virus, bacteria or parasite). It occurs mainly during the peri-partum period, in the days preceding or following calving, when blood flow to the udder increases abruptly in preparation for lactation. This excess vascular pressure causes an accumulation of interstitial fluid in the mammary tissues.
Udder edema in dairy cows does not spread, as it is a physical condition. Therefore, you do not have to worry about one cow infecting your herd. However, there are risk factors and certain practices that make your cows more prone to developing udder edema.

Udder edema can be very uncomfortable for your cows. It can affect milk let-down and, in the worst case, lead to further conditions like mastitis. However, the risk of udder edema can be reduced by taking the right measures.
By keeping an eye on your cows’ nutrition, encouraging regular movement, and creating a dry and comfortable environment, you’re already one step ahead of udder edema.
