EFFECT OF VACCINATION AGAINST INFECTIOUS RHINOTRAHEITIS OF CATTLE ON THE LEVEL OF REPRODUCTION
Infectious bovine rhinotracheitis(IBR) is a significant problem for dairy cattle. Live and inactivated vaccinesagainst acute respiratory viral infections, including IBR, are used in thebreeding enterprises of the Ural region. Methods of serological screening ofantibodies using common serological diagnostic tests do not allow to estimatethe origin of antibodies to the causative agent of IBR (vaccine or fieldstrain of the virus). The solution to differentiating field and vaccine strainswas the possibility of using modified monovaccines against IBR. The purpose ofthis study was to assess the effect of vaccination against infectious bovinerhinotracheitis with a labeled vaccine on bovine reproduction rates. The effectof labeled vaccines on cattle reproduction rates in a dairy herd withseroprevalence to a field strain (gE) of 95 % was evaluated. It has beenestablished that with the use of labeled vaccines, the seroprevalence in theherd during the first year decreased, on average, to 53 %, during the secondyear after the start of vaccination, to 14 %. 5 years after vaccination,seroprevalence was at the level of 5%. Simultaneously, reproduction rates wereevaluated. It was found that with the introduction of vaccination againstinfectious rhinotracheitis, the service period for cows was reduced by 13%(from 130 to 115 days), the number of afterbirth delays by 46 % (from 21.9 to15%), the number of stillbirths –by 12, 5% (from 2.7 to 2.4 %). Theuse of monovaccines for the specific prevention of IBR makes it possible tocontrol the appearance of infectious vulvovaginitis in cows and heifers indysfunctional infectious rhinotracheitis in cattle dairy farms. The use of a labeledvaccine makes it possible to evaluate the effectiveness of the prophylaxisbeing carried out and to monitor it at all stages of the rehabilitation offarms.
