Dietary supplementation with free methionine or methionine dipeptide mitigates intestinal oxidative stress induced by Eimeria spp. challenge in broiler chickens.

ABSTRACT:

Background

This study evaluated the effects of Eimeria spp. challenge and dietary supplementation with free methionine or methionine dipeptide on animal performance; expression of genes associated with the immune system, antioxidant system, and amino acid transport in the jejunum; and redox status of the jejunum of broiler chickens.

Methods

A randomized, 2 × 3 factorial design was used, in which Eimeria spp. challenge was the first factor (Eimeria-challenged, EC, or unchallenged, UC, broilers) and methionine supplementation was the second factor (non-supplemented, NS; free dl-methionine, dl-Met; and methionine dipeptide, dl-methionyl-dl-methionine, dl-MMet). At 14 days of age, chickens were inoculated orally with
