Summary
BROILACT, a competitive exclusion product, reduced Salmonella infantis in broiler chicks. The treatment showed a dose-dependent effect on infection levels but did not significantly impact bird performance over five weeks.
Area of Science:
- Animal Science
- Microbiology
- Food Safety
Background:
- Poultry farming faces challenges with Salmonella infantis contamination.
- Effective control strategies are crucial for broiler health and food safety.
Purpose of the Study:
- To evaluate the efficacy of a commercial competitive exclusion (CE) product, BROILACT.
- To assess the impact of BROILACT on Salmonella infantis infection in broiler chicks.
Main Methods:
- Pilot-scale trials with 100 broiler chicks per group.
- Challenge with Salmonella infantis via infected seeder birds.
- Weekly monitoring of Salmonella levels in caecal contents and bird performance over 5 weeks.
Main Results:
- A gradual decline in Salmonella infection was observed in both treated and untreated groups.
- BROILACT demonstrated a dose-dependent reduction in Salmonella infantis.
- No significant effect of BROILACT treatment on broiler performance was detected.
Conclusions:
- Competitive exclusion products like BROILACT can contribute to managing Salmonella infantis in broilers.
- Further research may be needed to optimize CE product application for enhanced efficacy.
- BROILACT shows potential for Salmonella control without negatively affecting broiler growth performance.
