Product Description

Induction and synchronisation of oestrus and ovulation in combination with prostaglandin F2 (PGF2α) or analogue with or without progesterone as part of Fixed Time Artificial Insemination (FTAI) protocols.

Treatment of delayed ovulation (repeat breeding).
A repeat breeder cow or heifer is generally defined as an animal that has been inseminated at least 2 or often 3 times without becoming pregnant, despite having regular normal œstrus cycles (every 18 -24 days), normal œstrus behaviour and no clinical abnormalities of the reproductive tract.

Dosage & Administration

Should be administered by intramuscular injection at a rate of 100 µg of gonadorelin (as diacetate) per animal in one single injection (i.e. 2 ml of Ovarelin® per animal). Should be injected during oestrus.

To improve significantly the pregnancy rates, the following timing of injection and insemination should be followed:

  • Injection should be performed between 4 and 10 hours after oestrus detection.

  • Artificial insemination has to be carried out after the injection of Ovarelin® in accordance with the usual field recommendations, i.e., 12 to 24 hours after oestrus detection (an interval of at least 2 hours between the injection of GnRH and artificial insemination is recommended).


  • Meat and offal: zero days
  • Milk: zero hours
