Johne's milk test

You can opt to test for Johne's disease as an additional health test at the same time as your herd test. This provides individual cow results to identify infected animals, to allow a management and prevention plan on farm.

If you are a myHERD herd recording customer, these results will flow through automatically into your herd records.

Gain from multiple herd tests

We recommend four herd tests in a season to get sufficiently accurate data to inform decisions around drying off, culling, breeding or animals which need animal health treatments. Adding an extra herd test is a good way to improve performance over time.

We’re on farm for every test

We provide a fully-trained Herd Tester at all Herd Tests, as part of the shed visit fee. The tester will set up the ICAR (International Committee for Animal Recording) approved meters, record volumes & take samples, all at the time of milking, which ensures accuracy of the data collected. Additional technicians are available on request.

For larger sheds/herds, an additional herd tester may be required. The assist can be provided by CRV or the farmer. This depends on size and shed flow/system, but generally 26-28 cups is the maximum for one herd tester.

More milk in the vat

Small samples of 30mls are taken, which means more milk in the vat & more room in the dairy.

We provide actual milk volume which matches your tanker docket, giving you confidence in the accuracy of the reports.

Flexibility around dates & timing

We do our best to offer flexibility when scheduling tests to suit our customers.

Recording with myHERD?

Receive a same day report

A same day production report is emailed to the farmer (*providing they are a CRV herd recording client & records are up to date and during business hours only).

Understand your environmental impact

Following two herd tests, and when recording with CRV myHERD, we can provide a report on your individual cow BV for Milk Urea Nitrogen (MUN).

The CRV Herd Testing Service is compliant with the ISO accredited standard ISO 9001:2015 and the NZ Herd Testing Standard NZS 8100:2015.

Before the milk test, raise vacuum to compensate for vacuum loss once herd test milk meters are installed, as meters typically use 2-3 kpa of vacuum.

The vacuum should be raised to 48kPa for low lines and for rotaries, 50kPa for milk lines above the cow. Switch to ‘Constant’ if available.

This is only needs to happen for the duration of the herd test.
