Probiotics, Probicon L28, BioPlus 2B, market pigs, performance, pre-harvest interventions
These data represent the growth performance of pigs enrolled in a study to determine the impact of two direct fed microbial products on Salmonella and Escherichia coli prevalence pre- and post-harvest. A total of 650 finishing pigs in two groups were randomly assigned to pen via a completely randomized design, and pens were assigned to one of three treatments: 1) a control treatment with pigs fed a standard corn-soybean meal finishing diet (with no added probiotic); 2) the control diets with Probicon L28 (NexGen Innovations, LLC, Lubbock, TX) supplemented through water lines using a water medicator system at a target concentration of 1.0 × 106 CFU/head/day; and 3) the control diet with added BioPlus 2B (5.0 × 108 CFU/lb of feed; ~3.0 × 109 CFU/ head/day; CHR Hansen, Inc, Milwaukee, WI). No evidence of difference (P > 0.10) between treatments was observed for overall ADG, ADFI, or F/G or any of the carcass traits. However, there was a tendency for a treatment effect for loin depth (P = 0.070). Pigs fed the BioPlus 2B treatment had numerically greater loin depth compared to other treatments, but there were no significant pairwise differences between treatments (P > 0.05). The results of this study suggested that probiotics used in this study and supplied through the water or feed had no impact on growth or carcass characteristics of finishing pigs.
