# Protective effects of inulin against lipopolysaccharide-induced oxidative stress in broiler chickens

## TL;DR

This study shows that inulin can help reduce oxidative stress in chickens caused by lipopolysaccharide, suggesting it could be a useful feed additive.

## Contribution

The study demonstrates inulin's protective role against LPS-induced oxidative stress in broiler chickens through Nrf2 pathway regulation.

## Key findings

- LPS reduced antioxidant enzyme activity and increased lipid peroxidation in multiple tissues.
- Inulin supplementation partially restored antioxidant capacity in LPS-challenged chickens.
- The protective effect of inulin is linked to the regulation of the Nrf2 signaling pathway.

## Abstract

This study was conducted to evaluate the protective effects of inulin against lipopolysaccharide (LPS)-induced oxidative stress in broilers.

A total of 108 1-day-old male Arbor Acres broilers were randomly allocated to 3 treatment groups with 6 replicates per group and 6 birds per replicate. The 3 groups were: (1) non-challenged broilers fed a corn-soybean meal basal diet (control group, CON); (2) LPS-challenged broilers fed the basal diet (LPS); (3) LPS-challenged broilers fed the basal diet supplemented with 15 g/kg inulin (LPS + Inulin).

The results showed that LPS administration inhibited activities of antioxidant enzymes and stimulated production of lipid peroxidation in multiple tissues including serum, liver, intestine, and muscle. Dietary inulin supplementation partially alleviated the negative effects of LPS on antioxidant capacity of these tissues, with the underlying mechanism involving the regulation of the Nrf2 signaling pathway.

Collectively, these findings indicate that inulin supplementation effectively alleviates LPS-induced oxidative stress, highlighting its potential as a feed additive in broiler diets to combat oxidative stress.
