PMSG is a hormone injection used to influence the breeding cycle in cows, sows, ewes and bitches. A veterinary prescription and treatment regime needs to be followed to ensure that treatment is effective.
PMSG is often used in conjunction with hormone-releasing Chronogest sponges. (Click to see them on VioVet.)
All prices include VAT where applicable.
PMSG-Intervet is presented as a white, freeze-dried crystalline plug containing 5000 iu Serum Gonadotrophin (PMSG) supplied together with solvent, which when reconstituted gives a solution containing 200 iu PMSG per ml.
PMSG is capable of supplementing and being substituted for both luteinising hormone and follicle stimulating gonadotrophin of the anterior pituitary gland in both the male and female, stimulating development of the ovarian follicle.
Make up immediately before use.
Reconstitute by dissolving the powder plug in about 5 ml of the solvent provided and then syringe the resulting solution into the solvent vial to mix with the remaining solvent. Administer by subcutaneous or intramuscular injection using normal aseptic precautions.
In conjunction with the use of progestagen treatment when used for oestrus control in non-cycling cattle:
1500-4000 iu - on day 9-13 of oestrous cycle.
Anoestrus post weaning (induction of oestrus is difficult until 40 days post partum):
1000 iu - s.c. or i.m. Fertile oestrus usually follows in 3 - 7 days.
In conjunction with progestagen-releasing sponges when used out of the normal breeding season:
500 iu - s.c. or i.m. at time of sponge removal.
Oestrus induction (subnormal oestrus with non-acceptance):
20 iu/kg - s.c. daily for 10 days. At day 10 injection of 500 iu hCG.
Superovulation in cattle
The product may be used for the superovulation of female donor cattle preparatory to embryo transfer. As an example, the following regime has been successfully applied:
A single dose of the product (1500 - 4000 iu) is injected on day 9 - 13 of a normal oestrous cycle (NB the exact dose of the product required to achieve effective superovulation will depend upon a number of factors particularly the breed, age, reproductive history, general health and nutritional status of the donor female and will be subject to individual variation). Forty-eight hours after the injection, luteolysis is induced by the injection of a prostaglandin analogue. Commonly one and a half times the normal luteolytic dose is administered. Oestrus normally occurs approximately 48 hours after the prostaglandin injection. Insemination is carried out at 60 and 72 hours after prostaglandin injection.
Collection of fertilised embryos (flushing) is carried out 6-8 days after insemination, suitable embryos being transferred to female recipient cattle whose oestrous cycles have previously been synchronised with that of the donor female.
(Experience has shown that oestrous cycles in donor and recipient females should be synchronised within ± 24 hours if reasonable success is to be expected.) A further prostaglandin treatment (commonly 1½ times the luteolytic dose) must be given at the time of collection.
PMSG is a protein hormone which acts on the ovary to stimulate the production of follicles. The number of follicles produced can be influenced by the dose of PMSG administered and this must be taken into account when calculating the dose for a particular flock of ewes. In general, the further out of season that breeding is attempted and the lower the normal prolificacy of the flock, the more PMSG that will be required. An average dose of 500 iu /ewe is recommended as a useful starting point but doses ranging from 200 - 750 iu have been used on occasion. It is therefore recommended that accurate flock records are kept of breed, dose given, time of injection and lambs produced so that in future seasons the amount can, if necessary, be adjusted for optimum results.
Where the possibility of multiple ovulations (due to exaggerated response from prolonged blood concentrations) has not been excluded by clinical examination following administration of PMSG to uniparous species (unless to induce superovulation in cattle), it is inadvisable to permit service or insemination during the first heat produced.
In rare cases, as with all protein preparations, anaphylactoid incidents may occur shortly after injection. Adrenaline injection (1:1000) given intravenously or intramuscularly when clinical signs appear is the standard treatment. The administration of corticosteroids may also be indicated.
Repeated administration can result in reduced efficacy due to immune-mediated antagonism.
Care should be taken to avoid accidental self-injection.
Wash your hands after use.

Below are some recent questions we've received regarding PMSG (Intervet), including answers from our team.
Do the body imune system of ewe form antibodies against pmsg..and for that can I use it again ..if I can how many month I can use it again.
The answer is not clear. The ewe will form antibodies to the product and this will tend to reduce its effectiveness with repeated use, but this does not usually completely prevent it from working at all in future. You should be OK to use it again at a suitable time for you. (Note that occasionally an anaphylactic response would be possible with repeated use and might require treatment.)
