Compact disc-read only memory (CD-ROM) is a popular electronic media which makes learning easy, interesting, multisensory and leaves a long lasting impression on the trainee. Therefore, this study aimed to develop a compact disc-read only memory on scientific calf management practices and to analyze its effectiveness in terms of knowledge gain as well as level of satisfaction among exposed dairy farmers. The study was conducted at Ludhiana where 120 dairy farmers were randomly selected among the various dairy trainings conducted from 2016–17. The CD-ROM was designed and contents were validated in consultation with subject matter specialists from the fields concerned. Suitable modifications were also introduced. Dairy farmers were exposed to it in order to measure their knowledge gain. There was significant (P≤.01) increase in the knowledge score from 5.74 ± 0.14 at pre-exposure stage to 12.68 ±0.14 at post exposure stage. Moreover, 76.67 per cent farmers were satisfied with respect to the suitability of contents of CD-ROM to their needs. The results of the study clearly indicated the importance of prepared CD-ROM in transfer of knowledge about scientific calf rearing practices.
