摘要:A module on disease prevention was created for 4-H volunteer leaders who work with livestock projects in Washington to better prepare them to teach youth about bio-security and its importance in 4-H livestock projects. Evaluation of the module and usage statistics since the module's debut were collected and evaluated. The module increases awareness of disease prevention and provides practical approaches to implementation of bio-security, but is underused by the target audience, possibly due to leaders' lack of computer access, time, or awareness of the module. Promotion of the module and incentives must be explored to increase module usage.
