The study proposes to analyse the livestock service delivery system in terms of service constraints farmers face while receiving it. The service providers considered in the study are veterinarians of State Animal Husbandry Department / government veterinary centres (GVC), Veterinarians from dairy co-operatives (public co-operatives), Veterinarians from private milk procurement agencies (private co-operatives) and Independent private veterinary practitioners or veterinarians who do private practice in their own capacity. Persons who are village level workers (VLW) from public or private co-operatives, Animal Husbandry Assistants or Livestock Inspectors from GVC are grouped together as para-veterinary professionals in veterinary/livestock services. A sample of 480 farmers were selected through multi-stage sampling procedure and statistical tools such as weighted mean score analysis was employed to get actionable insights into the challenges faced by farmers in accessing livestock services. The farmers were from four districts of Tamil Nadu, primarily identified by application of principal component analysis and composite index construction. Results revealed that lack of knowledge on animal insurance, service not delivered at preferred time, non-availability of service personnel at government veterinary centre, inconvenient working hours of hospital, lack of knowledge on vaccination, shortage of different drug types and lack of continuous service evaluation as the serious constraints faced in receiving livestock service delivery. The findings offer valuable guidance for enhancing the effectiveness and accessibility of service delivery systems in the livestock sector.
