Abstract
Introduction. In complex methods on preventive and control of infectious rhinotracheitis and bovine viral diarrhea, the main role belongs to the specific prevention using vaccine. The goal of the work was to conduct production tests of the preventive efficacy of the dry cell-derived vaccine against infectious rhinotracheitis and bovine viral diarrhea developed by the domestic biological industry. Materials and methods. Experimental work was conducted in stock-breeding farms SPK “Lopatino”, Republic of Belarus, vaccine development and virologic studies was organized in OUO “BELVITUNIFARM” and IE “Vitebsk state academy of veterinary medicine”. New vaccine used for immunized pregnant cows and calves at 40-45 days old. They were divided into 2 experimental groups and 1 control. In the experiment, calves from cows of the experimental and control groups were also used. They were also divided into 2 experimental groups and 1 control. Clinical observation continued for 45 days. All the dead and forcedly killed calves underwent autopsy and laboratory tests. Results of research and discussion. The constructed vaccine against infectious rhinotracheitis and bovine viral diarrhea after application to dry cows reduced the overall morbidity of calves by 35.2% and 4.4% respectively, in comparison with calves obtained from dry cows of the control group and from cows who were using imported biopreparation. When immunizing calves at the age of 40-45 days old, the overall morbidity of vaccinated calves decreased by 32.5% and 1.4%, respectively, compared with calves of the control group. Conclusions and prospects for further research. Vaccine against infectious rhinotracheitis and bovine viral diarrhea showed high preventive efficiency and it was recommended to use for specific prevention of these diseases.
