Improvac 100 ml

Composition

One dose (2 ml) contains: Gonadotropin releasing factor (GnRF) analogue-protein conjugate (a synthetic peptide analogue of GnRF conjugated to diphtheria toxoid) min. 300 mcg

Indications

Induction of antibodies against GnRF to produce a temporary immunological suppression of testicular function. For use as an alternative to physical castration for the reduction of boar taint caused by the key boar taint compound androstenone, in entire male pigs following the onset of puberty. Another key contributor to boar taint, skatole, may also be reduced as an indirect effect. Aggressive and sexual (mounting) behaviours are also reduced.

The onset of immunity (induction of anti-GnRF antibodies) can be expected within 1 week post second vaccination. Reduction of androstenone and skatole levels has been demonstrated from 4 to 6 weeks post second vaccination. This reflects the time needed for clearance of boar taint compounds already present at the time of vaccination as well as the variability of response between individual animals. Reduction of aggressive and sexual (mounting) behaviours can expected from 1 to 2 weeks

Dosage and administration

Improvac is for subcutaneous use. Entire male pigs from 8 weeks of age onwards should be vaccinated with 2 doses of 2 ml at least 4 weeks apart, with the second dose normally given 4 to 6 weeks prior to slaughter.
