Introduction: Undesirable bacterial colonization of farm surfaces affects animal health after weaning. The objective of the study was to test the preventive effects of a positive biofilm formation on the surfaces of piglet facilities on beneficial flora colonization and animal health.

Methods: 494 piglets from two weaning batches (Exp.1 and Exp.2) were allocated in 2 identical rooms. The rooms were sprayed either with water (Control) or a mix of selected bacteria strains (LFP) 48 h before the entrance, and again on day 15 in Exp.1, and on days 5, 12, 19, 26, and 33 in Exp.2. The microbiological status of the surfaces was assessed on days 0, 5, and 14 and on days -2, 0, 5, 7, and 35 in Exp.1 and 2, using peptone water swabs. Fecal consistency was scored on days 5, 8, 14, 21, and 28 on 16 randomly selected piglets per treatment. Statistical analysis was performed in SAS 9.4. Non-parametric tests were used to analyze the microbiological data, fecal scores, and death distributions.

Results: There was a significant (P<0.05) higher load of aerobic bacteria (Lactobacillus spp., Bacillus spp.) in LFP pen surfaces in both experiments. Fecal scores were significantly improved on day 8 in Exp.1 (P<0.01) and on days 9 (P=0.01) and 28 (P<0.01) in Exp.2. Digestive disease outbreaks occurred 2 days later in Exp.1 and 7 days later in Exp.2 in LFP rooms.

Conclusion: spraying a beneficial flora on surfaces may result in a protective positive biofilm that would help piglets to better deal with the weaning challenges.
