Abstract: The present study was carried out in an organized livestock farm at Jamdoli, Jaipur in Rajasthan state. The farm possesses145 animals which included 30 Non-descript white cattle, 38 Murrah buffaloes, and 36 (20 Sirohi and 16 Beetal) goats. Some animals in this farm i.e cattle, buffaloes and goats showed the clinical signs of poor weight gain, gradual decrease in milk yield. Based on the history of the animals, a detailed investigation was carried out to find the etiological agents responsible for poor performances. Accordingly all the animals above 6 months of age were tested for tuberculosis, paratuberculosis and brucellosis by skin allergic tests and by polymerase chain reactions. The study showed 8.33% Murrah buffaloes were positives for tuberculosis. In the farm animals no positive animals were found for tuberculosis in non-descript cattle and in goat population. The tests for J.D collectively showed 6.66% non-descript cattle, 2.7% Murrah buffaloes & 33.33% goats as positives. Studies on brucellosis showed none of the non-descript cattle, and Murrah buffaloes were found positives & 1% goats as positives. Overall studies revealed 2.9%, 14.7%, & 1% of the farm animals were tested positive for tuberculosis, Johne’s disease & brucellosis respectively. The associated predisposing risk factors for the prevalence of the above diseases were introduction of newer animals without quarantine, procurement of animals without screening for the above diseases, absence of regular screening, close confinement of the animals, intensive production system and problems in the disposal of the infected population because of socio-economic reasons.
