¹ Data represent the means of ten replicates (n = 10) at starter phase and six replicate (n = 6) at grower phase. CON, control group; OA, organic acids group; NSD, normal stocking density; HSD, high stocking density; BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; FCR, the ratio of feed to gain; SEM, standard error of mean. INT, interaction.
