[Immunoprophylaxis of infectious bovine rhinotracheitis].
The live attenuated vaccine against infectious rhinotracheitis (LAV), the live trivaccine against infectious rhinotracheitis (LT), the concentrated etanolsaponin vaccine against infectious rhinotracheitis (CESV) and the ethanol-saponin vaccine against infectious rhinotracheitis (ESV) can all be used as immunoprophylactic means in the control of infectious rhinotracheitis in cattle. The first two live vaccines are applied to calves in infection foci, and the two inactivated vaccines are used with cows. The comparative testing of CESV and ESV in experimental conditions on calves has shown that the first possesses higher immunogenicity--used in a twice lower dose it produces several times higher level of the neutralizing antibodies against the infectious rhinotracheitis virus. The use of LAV and LT in the practice under the conditions of established infections of infectious rhinotracheitis in calves has given good results. The immunization of calves at the immediate menace of this infection has lowered the morbidity rate, and death cases were no longer observed. The use of CESV and ESV with pregnant cows on a prophylactic basis against infectious rhinotracheitis has also given good results manifested in the full suppression of abortions.
