Why vaccinate for BRD?

Vaccination is an important
risk management strategy to
prevent BRD.

Bovine Respiratory Disease (BRD) is one of the most common
and costly diseases of cattle globally. Due to the intensification
of farming in New Zealand, BRD may now have a larger impact
than what we have seen historically. Most cattle are susceptible
to BRD at some point in their lifetime and it can impact performance.

Why Bovilis MH+IBR?

The only vaccine in NZ with a label claim to aid in the control of BRD

Of the numerous pathogens known to contribute to the development of BRD, Infectious Bovine Rhinotracheitis (IBR) virus is considered one of the most important viral pathogens and Mannheimia haemolytica (MH) is considered to be the predominant bacterial pathogen associated with BRD. 

Bovilis MH+IBR is the only vaccine in New Zealand which helps control both MH and IBR – and is the only vaccine in NZ to have a label claim to aid in the control of BRD.

Proven performance

Since its launch in 2011, Bovilis MH+IBR has been used extensively in the Australian cattle industry where it has been shown to be extremely effective at reducing levels of respiratory disease morbidity and mortality.

In a large Australian feedlot trial1, cattle vaccinated with 2 doses of Bovilis MH+IBR had significantly lower morbidity and mortality rates due to BRD than control cattle vaccinated with other vaccines.

Flexible primary dosing interval

Bovilis MH+IBR has a flexible primary dosing interval of 2 weeks to 9 months between the initial sensitiser and booster shots.

This extended vaccination interval allows farmers the convenience of aligning their vaccination schedule with other planned management practices

Immunity from 14 days following the 2nd dose

Bovilis MH+IBR vaccine provides active immunity 14 days after the 2nd dose.

For this reason vaccination should take place in advance of situations with high potential for BRD to occur. These situations may involve weaning, transport, mixing of cattle, weather extremes, dust, handling and change of diet.

Safe for use in pregnant cattle

Bovilis MH+IBR is formulated for safety in pregnant cattle.

This means farmers can administer the vaccine at any time of year.

When, how?

  • 2mL SC
  • 42 day broach claim
  • Flexible primary dosing interval of 2 weeks to 9 months between the initial sensitiser and booster shots
  • Active immunity established 14 days after 2nd dose
  • Safe for use in pregnant cattle
  • Nil with hold
  • Available in 100mL (50 dose) pack size with draw-off tube

What you need to know?

Bovine Respiratory Disease (BRD) is one of the most common and costly diseases of cattle globally.

BRD is caused by several viral and bacterial pathogens.

Mannheimia haemolytica (MH) and Infectious Bovine Rhinotracheitis (IBR) are two of the most important.2

BRD is a complex, multifactorial condition with a number of animal, environmental and management risk factors predisposing cattle to illness.

When risk factors converge, common viruses (like IBR), then bacteria (like MH), cause disease & spread.

Age of the animal, the pathogens involved, and the stage of the disease can influence the signs.

General signs include:

  • Fever
  • Depression
  • Loss of appetite
  • Dullness
  • Coughing
  • Rapid, shallow breathing
  • Watery, then purulent nasal and/or eye discharge
  • Excess salivation

Most cattle are susceptible to BRD at  some point, and it can impact performance.

Young, BRD-susceptible cattle in intensive situations may experience 25% morbidity3.

  • Increased sickness following stress events (eg, weaning/transport)
  • Reduced live weight gain4
  • Greater variation in mob weights
  • Reduce stress
  • Vaccinate animals against the BRD disease complex

Health risks & diseases

BVD (Bovine Viral Diarrhoea) is a viral disease of cattle which is wide-spread in New Zealand. Affecting both dairy and beef herds, it is estimated that about half of herds are “actively-infected” with BVD at any given time1 and the cost of BVD to the New Zealand cattle industry is around $150 million a year.2

BVD causes pregnancy loss, diarrhoea, milk drop, and reduced growth rates. It also suppresses the immune system, making animals more susceptible to other diseases, such as pneumonia and salmonella.

Research in New Zealand and overseas shows that it pays to control BVD; it is always more cost-effective to do something than to do nothing3. Moreover, a well-executed BVD control plan will help you achieve other farm goals, like improving animal welfare, reducing antibiotic usage, and improving reproductive performance.

BVD is spread by “persistently-infected” or “PI” cattle.  The key to BVD control is therefore to find and eliminate PIs from within your herd, then protect your herd from contact with outside PIs.   This can be accomplished by: monitoring the herd, testing individual animals, improving biosecurity, and strategically vaccinating ‘at-risk’ cattle.

Bovine Respiratory Disease (BRD) is a complex disorder of cattle causing respiratory disease and even death. It is caused by a combination of infectious agents and stress factors (weaning, transport, mixing, weather extremes, dust, handling and change of diet) acting on susceptible cattle in paddock and more intensive systems.

Signs of BRD include:

  • Fever
  • Depression
  • Loss of appetite
  • Dullness
  • Coughing
  • Rapid, shallow breathing
  • Watery, then purulent nasal and/or eye discharge
  • Excess salivation

Due to the intensification of farming, BRD may have a larger impact on New Zealand in the future than what we have seen historically. Most cattle are susceptible to BRD at some point, and it can impact performance.

Neonatal diarrhoea is arguably one of the most common diseases of newborn calves worldwide. The consequences on animal welfare and those managing the calves can be devastating. The cost of mortality, poor growth and performance as well as treatment costs, all need to be considered. The infectious agents that cause neonatal calf diarrhoea are prevalent in New Zealand. In a recent survey 96% of farms in New Zealand had pathogens that can cause calf scours detected1.
