The PORCIVET boar spray is used for providing standing oestrus during insemination of sows and gilts. CO2 is used as propellant. From a distance of approx. 60 cm the Porcivet Boar Spray is sprayed directly onto the snout of the sow/gilt. Spray for approx. 1 second and carry out the standing test. If the sow willingly accepts the pressure, she is ready for insemination.
