We are thrilled to see Waikato move back to Level 2 in the Covid response.

The challenge now is to adapt to life as we move from pandemic to endemic. At SVS Labs we see the appropriate level of measures as including

  • All our staff will be double vaccinated
  • All visitors will be asked if they are double vaccinated
  • We will wear face masks at the point of contact with visitors such as those dropping samples into Specimen Reception
  • There will be signage asking these visitors to wear a face mask
  • We will have our QR code available for scanning

We thank all our clients for the way you have worked with us through lockdown and with these ongoing steps which we are all seeing as part of our new normal.

Bulk Milk Sampling

The national survey of the bulk milk samples as part of response to M. bovis is underway. This is placing a great strain on the systems and resources and does take an understandable priority. We are still getting the samples for our BVD Testing Programme but we are seeing a delay of up to 2 weeks in the timing of these.

We apologise for any inconvenience caused by this and are doing all we can to turn the testing around as quickly as possible once we have the samples.

Thank you very much for your support and understanding in this matter.

BVD Beef Herd Programme

About 80% of beef herds have been exposed to BVD

Very few farms have conducted any monitoring

Most beef farms are in the dark on their status

BVD is having major effects on beef farming profitability through:

  • Increased empty rates
  • Increased time from calving to pregnancy
  • Sickness and poor growth in young stock

Use the SVS Labs BVD Beef Programme at the time of pregnancy scanning.
