Wet conditions can spawn more mastitis
Spring opens new windows of opportunity for mastitis infections to take hold. Wet, muddy conditions, especially in areas hit by heavy rainfall or flooding caused by snow melting, make it more difficult to keep cows clean. FULL STORY »
Use antibiotics appropriately
Different parts of the scientific and medical communities have been at odds with each other for some time over the use of antibiotics in livestock production and linking that to antibiotic resistance in humans. Even though scientific evidence currently supports continued use of antibiotics in livestock, it is important for producers to make sure they are using these products responsibly and judiciously.

Lowering SCC makes cents
Reducing cost and increasing volume are profit winners for every farm, says Jeff Reneau, University of Minnesota extension dairy management specialist. Since disease is a well-known profit robber, and mastitis is one of the most expensive diseases with which dairies must deal, it makes sense and cents for you to tackle it head-on. “Estimated mastitis losses for the U.S. dairy industry are $1 billion per year,” he says. “Ninety percent of this loss is lost production.

Back to basics: Milking procedures
A key factor for a good milking is the hormone oxytocin. Oxytocin is responsible for milk let-down, and without oxytocin, cows will not be milked out completely or rapidly. Oxytocin is released into the blood in response to various stimuli, and causes contraction of the udder’s muscle cells. Milk is available for removal from the udder because of these contractions. The process of oxytocin release can start with stimulation of the teats, specifically the teat ends, as this is where most nerve receptors are located. The sound of the vacuum pump in the parlor, or even the act of walking to the parlor, can also be stimuli for oxytocin release. Milking procedures either contribute to or depend upon this release of oxytocin. FULL STORY »

California researchers explore new mastitis control strategies.
Eight teams of researchers, educators and students from the University of California and California State University have received funding for projects to produce rapid results on topics as diverse as North Coast job development, improved irrigation practices for the San Joaquin Valley, and new technology to detect, monitor and treat mastitis in dairy cows.

What makes these farms excellent?
“I had the opportunity to learn a lot from the producers as they described how they have achieved such consistently good results,” explains Jeff Reneau, University of Minnesota professor of dairy management. “In reflecting on the comments I heard at each farm, observing the management practices first-hand and studying their DHI records, several familiar themes prevail.” FULL STORY »
Costly Klebsiella ID’d on New York farms
Coliform mastitis caused by Klebsiella species is a problem in New York State and at the Miner Institute. Klebsiella mastitis is particularly troublesome compared with Escherichia coli (another common cause of coliform mastitis) because of the severity of clinical episodes on milk yield and cow health, lack of an effective treatment, increased risk of culling or death, and lack of an effective vaccination program.
