Until recently, pig farming is taken up mostly as a traditional caste occupation and also by the socio-economically weaker sections of the society which might be due to various religious taboos and beliefs. However, due to various extension and technological interventions, many inquisitive people are coming forward to take up commercial pig farming as a livelihood. Field veterinarians, the middle level extension professionals involved in the service delivery system of livestock farming community, can promote pig farming among various population sectors and aid in the development of piggery and quality production. In order to promote pig farming and also to update and refresh the knowledge of field veterinarians of SDAH a study has been planned entitled as “DEVELOPMENT OF MOBILE APP ON PIG FARMING AND ITS ASSESSMENT AMONG FIELD VETERINARIANS OF ANDHRA PRADESH” A quasi experimental and ex-post-facto research design were adopted for the present study. The present study was conducted among 91 field veterinarians working in SDAH of Andhra Pradesh were selected purposively through stratified random sampling method. The data were collected through well designed questionnaire using both electronic and printed versions and the findings were coded, tabulated, analysed and interpreted.
