What is it?

Bovilis Nasalgen®-C is an intranasal live vaccine which can be used for active immunisation of calves from the day of birth onward to reduce clinical signs of upper respiratory disease and nasal viral shedding from infection with Bovine Coronavirus (BCoV).

It allows farmers and veterinarians to safely and effectively administer protection against BCoV in a single intranasal vaccination that can quickly reach the site of action. The onset of immunity starts five days after administration, with a 12-week duration. Bovilis Nasalgen®-C is available to use concurrently with Bovilis INtranasal RSP® Live. 

Why use it:

BCoV is quite prevalent in Irish herds, featuring strongly in calves and is much less prominent in older animals. It likes having a partner in that it is frequently co-detected with other BRD viruses such as Bovine Respiratory Syncytial Virus (BRSV) and Parainfluenza-3 Virus (PI3).

BRD is the most significant cause of deaths among calves greater than one month of age. BRD has a huge negative impact on growth and performance of both beef and dairy animals. Therefore, Consequences of the disease can manifest later in life with decreased milk production in the first lactation and decreased daily weight gain. For example, a dairy heifer calf can produce up to 120 kg less in her first lactation while beef animals can take up to 2 months longer to finish.
