Intended Use Vactora Plus is formulated for drinking water vaccination of poultry. It enables a more effective vaccination by constituting more appropriate drinking water. Specifications Free chlorine and heavy metals reduce the efficiency of live vaccines through drinking water vaccination applications. Vactora Plus chemically binds chlorine and heavy metal ions and eliminates their harmful effect to vaccine viruses. pH in drinking water should be between 6,5-7,0 in drinking water vaccination applications. Vaccine viruses lose their aliveness below these limits after one hour. Vactora Plus buffers the pH in drinking water to keep it between these limits and helps to keep the vaccine viruses alive for longer periods. Vactora Plus dissolves easily in water. Therefore, it does not cause precipitates or clogging in water lines. Vactora Plus constitutes a temporary blue colour in the beaks and corps of poultry. Scoring can be done by this way for the vaccinated flock. 20 gr Vactora Plus powder is presented in one sack.
