    Zinc oxide nanoparticles (ZnO NPs) are used widely in consumer and industrial products, however, their influence on gut microbiota and metabolism and their mutual interactions are not fully understood. In this study, the effects of ZnO NPs on ileal bacterial communities, plasma metabolites, and correlations between them were investigated. Hens were fed with different concentrations of ZnO NPs [based on Zn; 0 mg/kg (control), 25 mg/kg, 50 mg/kg, and 100 mg/kg] for 9 weeks.
  • Chromium (Cr) is one of the essential minerals which is required for improving productive performance in poultry due to its important functions in metabolism, growth and reduction of lipid and protein peroxidation. Under heat stress conditions, Cr plays a crucial role in poultry nutrition, production and health as well as enhances growth performance and quality of eggs in meat and egg type chickens, respectively. Supplementation of Cr may increase body weight gain, improve feed efficiency and there is also increase in carcass yield of broilers. Chromium is also a potent hypocholesteremic and antioxidant agent. The beneficial impacts of Cr have been linked with improved the metabolism and immune system.
  • There is a close relationship between the trace elements and the health of animal, especially the immune function, which is greatly, influenced by some trace elements, such as chromium, an essential element in animals. The effects of chromium on the immunity have been confirmed, thus, the aims of this review are to clarify the relationship between the chromium or chromium compounds on immune function in animals from the aspects of the evelopment and growth, histological structure of the immune organs, non-specific immunity, humoral immunity, cellular immunity and cytokines.
