CRV Herd Testing

Product benefits

  • A technician is provided as part of the service
  • Volumes are recorded on-farm
  • Flexible date scheduling

Herd testing is a valuable way of identifying the high and low performers in your herd.

For individual cows, Herd testing information can recognise:

  • Low producers (for culling or drying off)
  • High producers (for breeding)
  • Mastitis (for treatment or culling)
  • Animals requiring veterinary treatment (if herd testing regularly)
  • Beta-Casein type status (A2/A2)
  • Pregnancy Status

For the herd, herd testing information is used to:

  • Gain an overall picture of production
  • Monitor mastitis status

Fully-trained CRV Ambreed herd testing technicians attend every herd test to set-up meters, record volumes and take samples, which ensures the accuracy of data collected.

Extra technician service

For very large sheds or herds an extra herd tester may be required. This will be dependent upon shed size, but generally 26-28 cups is the maximum for one Herd Tester.

Colour coded reports

CRV Ambreed’s herd test reports are colour-coded, allowing you to see high and low results at a glance.

Text message service

There is also a text service available which can provide you with information needed to address any urgent issues (e.g. highest cell count cows).

Full herd test

A full herd test is carried our during afternoon and morning milkings within a 24-hour period. All cows in-milk must be tested and must be fully identified and recorded.

Contemporary group test

This allows you to herd test all lactating animals within a contemporary group, for example a group of cows of similar age and season of calving that are managed in the same herd.

Once-a-day test

This option is for herds that are being milked once in a 24-hour period. This is a popular option at the end of the season.

Test day model (single sample herd test)

This is a single-sample option for a herd milking twice-a-day. The herd is tested at either the morning or afternoon milking and the sample is then calculated into a 24-hour test result.

Somatic Cell Count test only

A SCC test can be performed over the whole herd or selected cows at either morning or afternoon milkings. No volumes are recorded. Results will be received within 48 hours.

16 Hour Milking

This option is for herds milking three times in a 48-hour period. A single sample is taken and a standard formula is then applied to convert the 16-hour milking into a 24-hour result.

INDIVIDUAL A2/A2 BETA-CASEIN TYPE COW TEST

CRV has the ability to analyse Herd Test milk samples for beta-casein types. This will result in a cow being classified into one of three categories;
1. A2/A2: This phenotype will result in only A2 type beta-casein in the milk.
2. A1/A2: This phenotype will result in an equal amount of A1 and A2 type beta-casein in the milk.
3. A1/A1: This will result in an onlyA1 type beta-casein in the milk.

BVD and Johnes Disease testing

As part of our herd testing service we can now test both bulk and individual samples for BVD and JD in collaboration with Disease Research Ltd (DRL).

 

CRV can pregnancy test during your herd test.

Milk Pregnancy Testing detects Pregnancy Associated Glyoproteins (PAGs) that are only produced by the placenta. As PAGs are produced throughout the whole pregnancy they are a reliable pregnancy marker. After calving it takes time for the PAGs to decline, so testing should not occur within 60 days post calving. It also takes time for PAGs to rise, so farmers need to wait for 28 days after mating.

  • Easy

Add to your herd test. No interruption to milk productivity, samples taken during milking or herd testing

  • Non-Invasive

No stress on the animal, hands off pregnancy detection, one less job to do

  • Accurate

98% accuracy* as early as 28 days after mating

* Laboratory trials on over 400,000 cows have shown the IDEXX milk pregnancy test accurately identifies 98.4% of pregnant cows. Data on file

 

Three Possible Results

  • Pregnant
  • No pregnancy detected
  • Re-Check

A re-check result is when a sample contains too small a quantity of PAGs to ensure that the cow is empty, but not enough to confirm that she is pregnant.

There are several possible causes:

  • A cow has been sampled too early: < 28 days of AI or < 60 days of lactation.
  • A cow has just aborted
