Curcumin and Resveratrol Regulate Intestinal Bacteria and Alleviate Intestinal Inflammation in Weaned Piglets

Area of Science:

• Animal Science
• Microbiology
• Immunology

Background:

• Piglets are susceptible to gut disorders during weaning due to immature immune systems and changing gut microbiota.
• Resveratrol and curcumin possess known anti-inflammatory and immune-modulating properties.

Purpose of the Study:

• To evaluate the effects of dietary resveratrol and curcumin on intestinal microbiota and inflammation in weaned piglets.
• To determine if these compounds can mitigate weaning-induced intestinal issues.

Main Methods:

• 180 piglets were weaned and fed diets with antibiotics, resveratrol and curcumin, or control for 28 days.
• Bacterial populations (e.g., Escherichia coli), Toll-like receptor 4 (TLR4) expression, inflammatory markers, and immunoglobulin levels were analyzed.

Main Results:

• Curcumin and antibiotics reduced Escherichia coli levels.
• Both resveratrol and curcumin downregulated intestinal TLR4 mRNA and protein expression.
• Inflammatory molecules (interleukin-1β, tumor necrosis factor-α) were inhibited, while immunoglobulin secretion increased.

Conclusions:

• Dietary resveratrol and curcumin effectively regulate gut microbiota in weaned piglets.
• These compounds alleviate intestinal inflammation by modulating the TLR4 signaling pathway.
• Resveratrol and curcumin enhance intestinal immune function in piglets.
