Тhe method of control and immunological potency of vaccine against PCV2 was developed and used.The terms of usage of demo variant of emulsion-vaccine against PCV2 were improved. The laboratory regulations of preparing and usage instructions for emulsion-vaccine against associative porcine circovirus infections were developed. Porcine circovirus infection being a part of different factorial diseases became widespread in the world (Magar R, e.a., 2000; Allan G e.a., 2002). Clinical features of such a disease have two main forms – as Postweaning Multisystemic Wasting Syndrome, PMWS and as Porcine Dermatitis and Nephropathy Syndrome, PDNS. It is becoming increasingly commonplace for different vaccines to be found out in the word against this very disease (Blanchard P, e.a., 2003; Пейсак З., 2009). But still in Ukraine there is not any developed method permitting to control its immunizing power that could clearly define the level of virus resistance of vaccinated pigs against different agents of this very disease on the territory of Ukraine. First of all it is important to be able to arrange registration of vaccines in Ukraine thus permitting a guaranteed entry at Ukrainian market only efficient medicines for PCVI2. Porcine circovirus infections affect a lot profitability of swine rearing as well as biosafety of human food chain and ecological situation altogether.

Key words: circovirus, pigs, diagnostic method, emulsion-vaccine, biotest, immune resistance.
