Current Status and Future Challenges in the Use of Bacteriocins to Modulate Ruminant Gut Microbiota.

Area of Science:

• Agricultural Science
• Microbiology
• Animal Science

Background:

• Antibiotic overuse drives bacterial resistance in animals and humans.
• Bacteriocins are antimicrobial peptides with narrow-spectrum activity, offering an alternative.
• Multidrug-resistant pathogens pose a significant global health challenge.

Purpose of the Study:

• To review the potential of bacteriocins and bacteriocin-producing bacteria in ruminant production.
• To explore their role in modulating rumen microbiota.
• To assess impacts on animal health, productivity, and methane reduction.

Main Methods:

• Literature review of studies on bacteriocins in cattle production.
• Analysis of bacteriocin mechanisms for treating mastitis.
• Examination of bacteriocin effects on rumen microbial composition and function.

Main Results:

• Bacteriocins show promise for treating bovine mastitis, reducing antibiotic reliance.
• Modulation of rumen microbiota by bacteriocins can improve feed efficiency and animal yield.
• Bacteriocin application may decrease methane production in ruminants.

Conclusions:

• Bacteriocins represent a viable strategy to combat antibiotic resistance in cattle.
• They offer a dual benefit of enhancing productivity and mitigating environmental impact.
• Further research into bacteriocin applications in ruminant agriculture is warranted.
