This dataset include records from the first two generation of selection of three rabbit lines. The objective was to improve feed efficiency accounting for social interactions within cage. In two lines the feed intake control is done using an electronic feeder, and in the third feed intake is controled at cage level. In the excel book provided, the date from the different lines are recorded in different pages. This dataset has been generated within Feed-a-Gene (H2020) and GENEF (Spanish INIA) projects. It is presented to fullfit the requeriments of Milestone 22 of Feed-a-Gene. This milestone basically aims to show that a selection experiment for feed efficiency on rabbits, accounting for social interactions, can be operationally conducted using an electronic feeder to record individual feed intake of animals raised in groups. This device has also been developed within the frame of these two projects.
