The veterinarians in Livestock Service Delivery face huge challenges while rendering livestock services particularly the challenges faced are huge when the services are offered in rural areas. Keeping this in mind, the study was conducted to identify and analyze the constraints faced by veterinarians in livestock service delivery in Tamil Nadu and propose sustainable solutions. Through the Multi-stage sampling technique, data was collected from 120 Veterinarians. In the first stage, the highly progressive districts and least progressive districts were identified by application of principal component analysis and composite index construction. From each district, 12 veterinarians from the Government Veterinary Centre, 6 veterinarians from Cooperatives, 6 veterinarians from private cooperatives, and 6 veterinarians from private practitioners. The constraints faced were studied through 6 dimensions: Machines, Materials, Men, Policy, and Time and Distance categories. These dimensions of constraints were analyzed through a weighted mean score approach and constraints of serious nature are identified and analyzed. These constraints from various categories or dimensions are also analyzed through factor analysis by the principal component approach. Key findings revealed that human resource constraints, including inadequate manpower, no promotional opportunities, and being burdened with administrative tasks, were the most significant barriers, accounting for 22% of the total variation. Workplace challenges, such as handling outbreaks, waste management, and occupational safety, accounted for 15%. Material constraints, including shortages of drugs and protective gear, and issues related to time and distance were also highlighted. Policy-related issues, such as budgetary constraints further exacerbated the problem. The study concludes that through improved infrastructure and policy reforms, livestock service delivery can be enhanced, and sustainable improvement in veterinary services can be achieved.
