<![CDATA[Reproductive recording is essential for effective rabbit breeding management, yet manual systems often hinder breeding stock selection at the smallholder level. This study developed a rabbit livestock recording website using The Five Planes framework and evaluated its usability under ISO 9241-11:2018 across effectiveness (success rate and error rate), efficiency (task completion time), and satisfaction (System Usability Scale/SUS). Testing was conducted in two iterative phases involving animal science students and active rabbit farmers as respondents. Phase I (5 respondents) yielded a success rate of 86.25%, an error rate of 11%, an efficiency of 53.05 seconds per task, and a SUS score of 63.50 (Marginal High). Following interface improvements, Phase II (20 respondents) recorded a success rate of 74.38%, an error rate of 12%, an efficiency of 66.91 seconds per task, and a SUS score of 66.13 (Marginal High). This decline is primarily attributable to the inclusion of farmer respondents with more heterogeneous digital literacy in Phase II, rather than a deterioration in system design. These findings indicate that while The Five Planes framework produced a functionally robust recording website, further refinement is needed to improve usability for users with lower digital literacy before broader implementation in smallholder rabbit farming.]]>
