Because cattle themselves are L. hardjo-bovis carriers and even calves can be a host when born, vaccination is the most commonly used method for control and prevention. The goals of an effective vaccination protocol are to provide long-lasting immunity, prevent clinical signs, and prevent renal colonization and urinary shedding.
“Research shows that there are differences among vaccines, which is why it’s so important for producers to work with their veterinarians to examine which one is right for their herd,” says Higdon. “Because of these new USDA approvals, dairy and beef producers now can use both Master Guard and Titanium vaccines with the confidence they will aid in preventing disease caused by L. hardjo-bovis.”
Both Titanium and Master Guard vaccines are available exclusively from AgriLabs distributors. The newly labeled Titanium 5 L5 HB is packaged in convenient five-, 10- and 25-dose boxes, and Master Guard 10 HB is available in 10- and 25-dose boxes.
“While we are adding “HB” to the names of Titanium 5 L5 and Master Guard 10 to call attention to the new USDA approval, the vaccines themselves remain the same,” says Higdon. “This means that people can continue using the Titanium 5 L5 and Master Guard 10 vaccines already in their refrigerators, knowing the cattle they vaccinate will receive the same protection against L. hardjo-bovis.”
About Master Guard 10 HB
Master Guard 10 HB is a combination modified-live and killed vaccine that provides five-way viral and five-way Leptospira protection in a single dose, while enabling cows to maintain milk production. Master Guard 10’s killed Bovine Viral Diarrhea (BVD, types 1 and 2) and Infectious Bovine Rhinotracheitis (IBR) fractions offer safety at any stage of lactation; its modified-live Parainfluenza3 (PI3) and Bovine Respiratory Syncitial Virus (BRSV) fractions maximize immune response. Now approved to prevent disease caused by Leptospira borgpetersenii hardjo-bovis, Master Guard may be administered to healthy dairy and beef cattle at least 5 months of age, including pregnant cows. Master Guard vaccines are manufactured using continuous Signature Cell Line® production for serial-to-serial consistency and quality.
About Titanium 5 L5 HB
Titanium 5 L5 HB is a modified-live vaccine that provides five-way viral and five-way Leptospira protection. Titanium was the first vaccine to protect against both type 1 and type 2 BVD, and also offers safe, smooth protection against IBR, PI3 and BRSV. Now approved to prevent disease caused by Leptospira borgpetersenii hardjo-bovis, Titanium 5 L5 may be administered to healthy dairy and beef cattle that are not pregnant or nursing. Titanium vaccines are manufactured using continuous Signature Cell Line production for serial-to-serial consistency and quality.
