Rotavec Corona®

As an experienced veterinarian, it was demoralising for Mara Elton Fletcher to watch a severe rotavirus scours outbreak unfold on her own dairy farm.

Mara and her husband, Hayden, milk 930 cows in Culverden, North Canterbury, and despite having top-quality colostrum management and hygiene practices in place, their herd was hit hard with a rotavirus outbreak, prompting them to vaccinate the entire herd last year with Rotavec Corona.

Rotavec® Corona

Increases antibodies in colostrum and milk

Calves are born without antibodies to fight infection. They rely completely on high-quality colostrum for protection against scours-causing pathogens.
It is critical that calves receive enough of the right antibodies in colostrum, and then in transition milk, to reduce their risk of scours.
Rotavec Corona significantly elevates neutralising antibodies in colostrum and milk for at least 28 days post-calving. 1

Boosts levels of both G6 and G10 antibodies

Cows vaccinated with a single serotype produce antibodies to all serotypes to which they have had prior exposure. This response has been demonstrated by numerous researchers. 2,3,4

Reduced environmental contamination

Faeces from calves fed colostrum from Rotavec Corona vaccinated cows contain less virus. This results in reduced environmental contamination and less likelihood of virus spread to uninfected calves. 5

Save you and your calves the pain and ask your vet about
Rotavec Corona – your proven scours solution.
