Weaning Induced Gut Dysfunction and Nutritional Interventions in Nursery Pigs: A Partial Review

Area of Science:

• Animal Science
• Microbiology
• Gastroenterology

Background:

• Weaning is a major stressor for pigs, often causing gut microbiota dysbiosis.
• This dysbiosis can lead to intestinal and immune dysfunction, affecting growth, morbidity, and mortality.
• The gut microbiota is a vital 'organ' producing beneficial metabolites.

Purpose of the Study:

• To review weaning-associated gut microbiota dysbiosis in pigs.
• To emphasize the importance of a balanced gut microbiota.
• To discuss dietary interventions for restoring gut balance and improving piglet growth.

Main Methods:

• Literature review on weaning-associated gut dysbiosis.
• Analysis of the role of gut microbiota in piglet health.
• Evaluation of dietary supplements for gut health.

Main Results:

• Weaning triggers significant changes in pig gut microbiota composition.
• Gut dysbiosis negatively impacts intestinal integrity and immune function.
• Dietary supplements show potential in mitigating weaning stress effects.

Conclusions:

• Maintaining a balanced gut microbiota is crucial for weaning piglet health.
• Dietary strategies can effectively restore intestinal balance.
• Supplementation can improve growth performance and reduce mortality in weaned pigs.
