Nano-Selenium affects on duodenum, jejunum, ileum and colon characteristics in chicks: An animal model

Selenium has many roles on the functioning of humans and animals. Chicks as animal model can play an important role to distinguish the role/function of selenium. The objective of the present study was to test the effect of variable doses of nano-selenium supplement on the chicken gastrointestinal tract. A total of ۱۸۰ male Ross chicks were divided into six groups, with three replicates for each group and ten birds per replicate. Group ۱ was the control group and was fed standard feeding for full experiment. Groups ۲-۶ were given variable doses of nano-selenium supplement from ۱st-۴۲nd days of age; Group ۲ (۰.۱ mg/kg), Group ۳ (۰.۲ mg/kg), Group ۴ (۰.۳ mg/kg), Group ۵ (۰.۴ mg/kg) and Group ۶ (۰.۵ mg/kg). The results showed a decrease in the weights of small and large bowels with simultaneous increase in their lengths. Optimum doses of supplementary nano-selenium for bowel development are suggested.
