Predi'Bov^® is an ovulation test specifically designed for use on cattle. The timing of ovulation can be determined by using the test (carried out on a few drops of whole blood,) which detects the LH peak which does set off the ovulation 24 hours later.

Predi'Bov^® allows its user to determine and anticipate precisely the optimal timing to carry out an artificial insemination which is 12 hours after a positive test reading.

> An ovulation test for use on farm.

 Predi'Bov^® can be used on cows and heifers and has been tested on several breeds (Holstein, Montbéliarde, Charolaise, Blonde d’Aquitaine ...). Predi'Bov may be used on farm or in stations by anybody involved in the husbandry of the female (farmer, technician, veterinary surgeon). It will detect the LH peak either in a natural cycle or in an artificially induced cycle.

> Simple colour reading, no risk of false positives.

Predi'Bov^® is easy to use, no need for special kit.
Predi'Bov^® gives an answer quickly: it takes only 40 minute to carry out.
Predi'Bov^® is easy to interpret :

• if the stick stays white, there is no LH peak, the female is not ready for insemination
• if blue appears on the stick, the LH peak is happening, the female should be inseminated 12 hours later

In cows, the pre-ovulatory LH peak induces the ovulation 24 hours later and is therefore the most precise predictor of the optimal timing for artificial insemination (AI). Previous research has shown that AI success rates and results in terms of viable embryo production are significantly improved when AI is carried out 12 hours before ovulation, ie 12 hours after the LH peak (Maurel et al 1994, Lafri et al 2002).

The detection of the pre-ovulatory LH peak by using Predi’Bov allows timing the AI at the optimal timewhich is 12 hours after a positive reading of the test.

Predi'Bov® allows to :

• Detect LH peaks in order to do AI at the best possible time in relation to the timing of the ovulation.
• Optimize viable embryo production (up to 2 more embryos per collection).
• Get best value from the investment in semen.

Blood sampling

Just a few drops of blood are needed to carry out a test.

The blood can be collected at the back of the ear (using the lancet provided), at the jugular vein or at the back of the tail (using a heparin coated-vacutainer tubes).

A 3 step process with rinsing phases in-between steps:

• Put 5 drops of blood in tube 1 and insert stick.
  • Leave for at least 15 minutes, then rinse using the pot provided.
• Take tube 2 (with yellow cap), remove cap and screw in the stick.
  • Leave for at least 15 minutes, then rinse using the pot provided.
• Take tube 3 (with blue cap), remove cap and screw in the stick.
  • Leave for at least 10 minutes, and then unscrew the stick for color reading:
    
    
    • If the stick end is BLUE : the test is positive, the LH peak is ongoing. The cow must be inseminated 12 hours later.
      NB : The test is positive whatever the blue color intensity.
      
      
    • If the stick end is WHITE : the test is negative, there is no LH peak. Repeat test according to recommendations.
