Abstract: This experiment was conducted to study the effects of electronic feeding station on growth performance and behavior in growing pigs. One hundred and twenty-two Large White growing pigs with initial weight of 28.2 kg were randomly allotted into 3 groups, experiment group 1(general 15 head groups), experiment group 2(station 15 head group) and experiment group 3 (station 8 head group) by pens. The experiment 1 and 2 groups had 3 replications respectively, and experiment 3 had 4 replications. The pigs were stratified by sex. Feeding period was 44 days. Before the test, the accuracy of the station was evaluated. During the experiment, growing performance and skin lesion were tested, and pigs' behavior was recorded. The results showed that the accuracy of the station trough and weight weighing scale met its technical parameters. The performance of pigs had no significant difference in three groups(P>0.05). The coefficient of variation (CV) of experiment group 3 final weight decreased by 44.48%. The final weight, average daily gain (ADG) and average daily feed intake (ADFI) of experiment group 1 were slightly higher than experiment group 2. The electronic feeding station highly significantly increased pigs' skin lesion(P<0.01). Experiment group 1 highly significantly increased the aggression behavior on 1st day (P<0.01), and highly significantly decreased the aggression behavior on 7th day (P<0.01). Feeding behavior of experiment group 2 was relatively lower. The electronic feeding station significantly(P<0.05) or highly significantly (P<0.01) increased pigs' pen mate manipulations.
