This study was undertaken with the goal of improving the Indian dairy sector by enhancing knowledge and skill among dairy farmers on animal health care; thereby enabling increased productivity and minimizing economic loss. The study focused on members of milk co-operative societies of Kannur district, Kerala, India. Though the milk co-operatives were organized institutions, they lacked much needed knowledge and skill enhancement of their member-farmers. Most rural households in Kerala own television sets and DVD players. Hence, an educational interactive video-DVD on dairy health management practices was considered as an appropriate medium to disseminate knowledge on dairy health management practices to them. Sixty dairy farmers owning a DVD player and a television were selected as the sample population for study by means of proportionate random sampling among four milk co-operative societies identified in Kannur block. The findings of the study revealed that the majority of the respondents possessed medium level of knowledge at the pre-exposure stage, while in the post-exposure stage, a majority rose to the high knowledge category. The respondents who had low knowledge regarding various livestock diseases, their causes, symptoms, prevention and control gained considerable knowledge after exposure to the educational interactive video-DVD. The difference observed between the mean scores of knowledge level of respondents in pre and post-exposure stages was found to be statistically significant
