Proving the efficacy of Biotronic® Top liquid in water sanitation

A trial was conducted to evaluate the efficacy of Biotronic® Top liquid on the reduction of E. coli in the gut and liver of poultry in a challenge model compared with broad spectrum antibiotics. In this trial, three groups of 60 1-day-old female turkey were assigned: a control group without a water sanitation program, an antibiotic group with 0.5 ml of enrofloxacin per liter of drinking water, and an organic acid group with 1.25 ml of Biotronic® Top liquid per liter of drinking water. At 10 days old, all birds were orally challenged with E. coli O78 (1.3x108 CFU/mL). Ten birds from each group were sacrificed at 10 and 20 days post challenge (DPC) for bacterial count and lesion scoring. In this trial, Biotronic® Top liquid in water showed efficacy in reducing the number of E. coli in the intestinal tract and liver (Figures 1 and 2). Lesion scores at 10 and 20 DPC also showed that Biotronic® Top liquid could protect the birds from an E. coli challenge (Figure 3). All parameters evaluated in this trial indicated that Biotronic® Top liquid was the most effective tool to reduce the risk of bacterial infection in poultry production.
