The evaluation of potential immunotoxicity induced by environmental pollutant ammonia in broilers

Ammonia (NH3) is a harmful gas with irritating odor, and higher NH3 concentration was found in intensive poultry houses. Although the toxicity of NH3 is well known, little attention has been given to the mechanism of NH3 poisoning in chicken immune organs. To investigate NH3-caused inflammatory damage of broiler spleens, in this study, a broiler model for NH3 poisoning was established, and 3 levels (including microRNA [miRNA], mRNA, and protein)...
