Comprehensive Guide to Bovine Respiratory Disease and Cattle Vaccination Protocols

What is the largest contributor to morbidity and mortality in cattle?

Bovine respiratory disease (BRD)

What percentage of feedlot calf morbidity is attributed to BRD?

Approximately 75%

What is the estimated annual cost of BRD to the cattle industry?

About $1 billion US dollars

What are the primary stressors that can lead to BRD in calves?

Weaning, transport, comingling, overcrowding, dehydration, and new environment

What is the pathogenesis of BRD?

Stress immunocompromises calves, leading to viral infections that allow gram-negative bacteria to proliferate in the lower respiratory tract, causing tissue damage and potentially death.

What are the main bacteria associated with BRD?

Pasteurella multocida, Mannheimia haemolytica, Mycoplasma bovis, Histophilus somni

What viruses are commonly associated with BRD?

Parainfluenza 3 (PI3), Infectious bovine rhinotracheitis (IBR), Bovine virus diarrhea (BVD; Types 1 and 2), Bovine respiratory syncytial virus (BRSV)

What is the purpose of the Cattle Master Gold FP5 vaccine?

To prevent BRD caused by viruses such as IBR, BRSV, PI3, and BVD, as well as to prevent abortions caused by IBR.

What does the Reprostar VL5 HB vaccine protect against?

It protects against Campylobacteriosis and Leptospirosis, preventing abortions and the birth of weak offspring.

What is the function of the Covexin 8 vaccine?

It protects against bacterial infections from the clostridial family, including tetanus and enterotoxemia.

What is the role of Multimin 90 in cattle processing?

It provides essential minerals such as zinc, manganese, selenium, and copper.

What is the significance of the Inforce 3 vaccine?

It is an intranasal vaccine that prevents BRD caused by viruses BRSV, IBR, and PI3.

What is the purpose of the Presponse HM vaccine?

To provide immunity from bacteria associated with BRD, specifically Pasteurella multocida and Mannheimia haemolytica.

What is the recommended vaccination protocol for calves at birth?

Inforce 3, Cattle Master Gold FP5, Multimin 90, ST-BAC Implant, and Tri-Start.

What does the term 'persistently infected (PI) calves' refer to?

Calves that are born infected with BVD while the cow was pregnant, shedding the virus without showing obvious symptoms.

What are the signs of BVD in calves?

Diarrhea, fever, lethargy, loss of appetite, and respiratory problems.

What is the vaccination schedule for calves 3-5 months old?

Cattle Master Gold FP5, Presponse HM, Covexin 8, and Multimin 90.

What is the vaccination protocol for cows one month before calving?

Cattle Master FP5 L5, Bovine Rotavirus-coronavirus vaccine, Multimin 90, and Deworm.

What is the function of the Bovine Rotavirus-coronavirus vaccine?

It protects against rotavirus and coronavirus, which cause diarrhea in calves.

What is the role of the ST-BAC Implant vaccine?

It helps prevent pneumonia and BRD through a time-release pellet/implant.

What is the significance of using a repeater syringe or vaccine gun?

They allow for precise dosing and efficient administration of vaccines and injections.

What are the common dewormers used in cattle processing?

Cydectin, Ivermectin, Safe-guard, and Valbazen.

What is the importance of colostrum for calves?

Calves receive antibodies from their mother's milk, primarily colostrum, which is crucial for their immunity.

What is the recommended dose for the Cattle Master Gold FP5 vaccine?

2mL SQ for calves.

What does 'SQ' and 'IM' stand for in vaccination protocols?

'SQ' stands for subcutaneous injection, and 'IM' stands for intramuscular injection.
