Label: PLUSET- porcine follicle stimulating hormone, porcine luteinizing hormone kit

PLUSET is a mixture of swine pituitary gonadotrophins used for the induction of multiple ovulations (superovulation). The use of standardized concentrations for both gonadotrophins guarantees a consistent quality of the product and eliminates possible variability in effectiveness from one lot to another. In the absence of an International Standard for the porcine gonadotrophin, dosing is carried out using the International Standard for human urine FSH and LH.

Ovarian stimulation with exogenous Follicle-Stimulating Hormone (FSH) allows a greater number of ova to be produced than normally produced in a single reproductive cycle.

The pituitary hormone extract contains variable levels of Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

Clearly in order to obtain proper and effective superovulation which provides satisfactory results involving a high number of living embryos, it is necessary to carry out a treatment that guarantees the activation and progress of multiple follicle maturation in the most "physiological" and repeatable way possible.

Thus, given that it influences the activity of FSH, it is important to have a defined level of LH present.

PLUSET is manufactured in a method chosen to ensure that the defined level of LH content is consistently mantained.

Kinetic studies of FSH and LH in the bloodstream of bovine has shown a half-life of 150  minutes for FSH and a half-life of 40 minutes for LH.

To induce superovulation in reproductively mature heifers or cows. 

Do not use in pregnant animals.

Special warnings

The following recommendations for the use of PLUSET for the induction of superovulation with adequate response should be followed:

a.The donor animal must have had at least one normal oestrous cycle prior to the initiation of PLUSET treatment.

b.The donor animal should not have any signs of clinical illness when treatment with PLUSET begins. Ovarian examination should confirm the presence of a functional corpus luteum and the absence of any pathological conditions such as cystic ovarian degeneration or adhesions around the ovaries.

c.Treatment should be initiated between day 9 and 12 of the oestrous cycle (with day 11 generally giving best results).

d.      A luteolytic dose of prostaglandin F2 alpha or analogue should be given intramuscularly at 60 and/or 72 hours after the beginning of superovulation treatment.

e.Standing oestrus will take place 40-48 h after prostaglandin treatment and animals should be bred 12 h after the onset of standing heat and, again 12 h later with high quality semen.

f.      Following the non-surgical recovery of embryos on day 7, it is recommended to give the animals another prostaglandin treatment to assure a rapid return to heat; if not, animals should be examined 4 weeks after, to ascertain that normal ovarian activity has been restored. Breeding can take place at the first heat after superovulation, which normally is seen after 28 days.

g.The effect of repeated treatments with PLUSET over long periods has not been assessed for all possible schedule treatment  Therefore it is recommended that PLUSET not be administered more than twice for superovulation and that at least one natural oestrus cycle be allowed to occur between the two superovulation treatments.

h.The interval from calving to initiation of superovulation treatment should be at least 3 months.

i.Individually variability of responses depending of age, breed, on reproductive status, could occur.

User warnings

Care should be taken when handling the product to avoid self-injection.  Accidental self-injection may cause biological effects in women and to the unborn child.  In the event of accidental self-injection in women who are pregnant, or whose pregnancy status is unknown, seek medical advice.

Do not use during pregnancy

A slight reduction in milk yield has been observed during superovulatory heat (as in other heats) but the production in general reaches pretreatment levels within 2 weeks.

It is not advisable to exceed the maximum recommended dose. High doses of FSH and LH could be associated with reduced fertilisation rate, resulting in an increase of unfertilised embryos.

Dissolve each vial of freeze-dried product with 10.5 ml of solvent.

Use aseptic technique during reconstitution and when removing aliquots from the vial.  Adequately clean and disinfect the vial closure prior to each entry with a sterile needle.

Mix gently during reconstitution. 

PLUSET is to be given by intramuscular injection only.  

The following treatment schedule is recommended for the induction of superovulation in the cow:                     

The total recommended dose is 800 to 1000 IU in decreasing doses for 4 to 5 days. Considering the variability between animals and taking into account breed, age and reproductive status the dosing schedule should be adjusted appropriately. It is therefore recommended to seek veterinary advice on appropriate dosing patterns. For heifers and beef cows a total dose of 800 IU is recommended. For dairy cows the dose could be increased to 1000 IU taking into account increasing age, parity number and dairy production.

Recommended schedule for 800 IU in 4 days:

Recommended schedule for 1000 IU in 5 days:

* Corresponds to the 11th day of the oestrus cycle.

** A luteolytic dose of prostaglandin F2 alpha should be administered intramuscularly at 60 and/or 72 hours after the beginning of superovulation treatment.
