BookPublisher: 1994Subject(s): Department of MicrobiologyDDC classification: 0392,T Dissertation note: The project was designed to find out the prevalence of bovine viral diarrhoea BVD virus antibodies in the sera of local and exotic cattle breeds, randomly selected from four different sources. For this purpose one thousand serum samples were collected and agar gel diffusion technique was used for the detection of antibodies against BVD.
The results of the study revealed that an overall 11.4% cattle population was having antibodies against BVD virus. The prevalence of the BVD in local breed was 14.4% while that of exotic breed was 8.4%. The prevalence rate of antibodies against BVDV was found higher in local cattle breeds as compared to exotic breeds. Various epidemiological factors were considered. Age of the animal was an important factor influencing the prevalence of disease. So regarding the age of the animal high prevalence rates were found in adult as compared to young animals. Maximum number of reactors were found in the adult age group.
The finding of the survey revealed a moderate exposure in cattle population. The occurrence of antibodies against BVD virus in apparently healthy unvaccinated animals was indicative for prevalence of the disease in the country. Therefore it is suggested that a complete survey should be carried out for this problem throughout the country and appropriate control measures for the disease.
