Bovine Johne’s Disease (BJD) is a chronic granulomatous enteritis that affects ruminants worldwide and is having significant impact on the world economy and has been frequently reported from farm and farmer’s herds. An attack of Johne’s disease in a newly established cattle dairy farm consisting of high yielding Holstein Friesian (HF) cows in the Alwar district of Rajasthan was investigated for the first time in India. Since slaughter of cows is prohibited in India therefore management of bovine JD is critical for the success of dairy industry in the country and in this aspect the research paper is significant. Out of a total of 35 fecal samples screened by microscopy, 24 (68.5%) were positive for Mycobacterium avium subspecies paratuberculosis (MAP). Screening of 26 serum and 23 milk samples by ‘Indigenous ELISA kit’ employing semi-purified antigen of native strain (‘S 5’) of MAP, 24 (92.3%) and 14 (60.8%) were positive, respectively. Sensitivity of ‘Indigenous serum ELISA’ with reference to fecal microscopy and milk ELISA was 88.2 and 90.0%, respectively. Screening of blood samples of 14 cows, by specific PCR (IS900), 5 (35.7%) were positive. Genotyping of PCR positive HF crossbred cows using IS1311 PCR-REA showed presence of highly pathogenic ‘Indian Bison type’ genotype. Comparison of 3 tests (milk ELISA, fecal microscopy and IS900 PCR) with ‘Indigenous serum ELISA’ revealed substantial agreement between tests. Study also reported serious economic losses in terms of productivity (reduced quality and quantity of milk), reduced fertility and conception, decreased body weight and growth rate which left the farmer economy devastated due to attack of Johne’s disease in high yielding cattle herd of HF crossbred cows.
