Your Troubles Could Add Up to Salmonella

It starts as a bad string of events. Pregnancy checks don’t meet goals, milk production drops or a new ration shows no response in the bulk tank. You could call it a bad week, assume something was wrong with the feed or blame the weather. But, a U.S. Department of Agriculture study showed, farms are increasingly at risk for Salmonella.1

“It could be the single factor preventing your cows from reaching their potential,” cautioned Gary Neubauer, DVM, Zoetis.

Subclinical Salmonella symptoms include reduced milk yield, poor reproductive performance, abortions, weight loss and poor feed efficiency. The majority of Salmonella cases are subclinical, with clinical cases representing just the tip of the iceberg. Even if the subclinical indicators are only represented in a fraction of your herd today, tomorrow could bring the devastating clinical signs of fever, diarrhea and even death associated with Salmonella infections.

Salmonella has probably had ample opportunity to infiltrate your herd. Pests, vehicles and people all can carry the bacteria with them from another location. Cleanliness and biosecurity can help prevent Salmonella from sticking around. But vaccinating the entire herd at dry off with SALMONELLA NEWPORT BACTERIAL EXTRACT VACCINE* with SRP® technology may help minimize symptoms and prevent future outbreaks of Salmonella Newport.

If Salmonella enters your herd, cattle with subclinical disease can shed the bacteria through manure and/or milk. The disease most commonly spreads through oral ingestion of infected fecal matter. Some subclinical carriers will be symptom-free, and others won’t shed Salmonella but still can be latent carriers.

“In addition to the symptoms in cows, young calves are particularly susceptible to Salmonella. Calves can develop scours, severe blood infections, fever, pneumonia, arthritis and sudden death as result of an infection,” Dr. Neubauer said.

With more than 2,500 serotypes of the bacteria, Salmonella can appear on your farm in many different ways. Your veterinarian can perform a simple test of manure or the milk line to see if your herd is affected today. In addition to cleaning equipment and putting biosecurity procedures in place, using a whole-herd vaccination can help limit shedding of the bacteria and help prevent future outbreaks. Some cattle can shed Salmonella in their manure for more than a year.2 The pathogen can survive in water or on equipment for long periods of time, as well.
