Microbiota in fermented feed and swine gut.

Area of Science:

• Animal Science
• Microbiology
• Nutritional Science

Background:

• Antibiotic growth promoters (AGP) are widely used in swine production but their use necessitates alternatives due to growing concerns.
• Understanding the gut microbiota's role is crucial for developing effective AGP alternatives.
• Fermented feed (FF) presents a novel nutritional strategy with potential benefits for swine gut health.

Purpose of the Study:

• To review the impact of fermented feed (FF) on swine gut microbiota.
• To explore FF as a viable alternative to antibiotic growth promoters (AGP).
• To discuss the mechanisms by which FF influences gut microbial composition and function.

Main Methods:

• Literature review focusing on studies investigating fermented feed and swine gut microbiota.
• Analysis of existing research on the effects of FF on microbial shifts in different gastrointestinal tract (GIT) regions.
• Discussion of the potential prebiotic and probiotic effects of FF components.

Main Results:

• Fermented feed (FF) supplementation can positively modulate the swine gut microbiota.
• FF may lead to a shift in microbial balance favoring beneficial bacteria.
• The effects of FF are observed across various regions of the gastrointestinal tract (GIT).

Conclusions:

• Fermented feed (FF) shows significant potential as a natural alternative to AGP in swine diets.
• FF's positive influence on gut microbiota can contribute to improved pig productivity.
• Further research is needed to optimize FF fermentation and evaluation methods for consistent benefits.
