In December 2010, Zoetis announced the availability of an effective vaccine to help control salmonellosis caused by Salmonella Newport. SRP® Salmonella effectively helps control disease and fecal shedding of Salmonella Newport, resulting in reduced disease incidence.

Milk production and herd performance of cattle subclinically infected with Salmonella Newport can improve through greater control of salmonellosis in vaccinated herds. A published study conducted in a dairy herd with no clinical signs of salmonellosis demonstrated that vaccination using the Salmonella Newport Bacterial Extract vaccine resulted in 2.5 pounds more milk per cow per day in vaccinated cattle. There also was a reduction in somatic cell count associated with vaccination.1

Salmonellosis is an economically devastating disease to the dairy industry, and incidence is on the rise. According to the 2007 National Animal Health Monitoring Service report from the U.S. Department of Agriculture, 39.7 percent of all dairies were infected with Salmonella.2 The percentage of operations infected with Salmonella was nearly twice that of 1996, and over that same 10-year time period, the percentage of cows infected with Salmonella has more than doubled to 13.7 percent.

Salmonella is a pervasive pathogen that is hard to keep out of dairy operations. That’s why it’s important to get out ahead of it with an effective management tool such as a vaccine. Want to know how the vaccine works? This video explains it all.
