Quick Answer
Selenium Antioxidant Status Randomized Trial has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: Heat stress leads to a decrease in feed intake and feed conversion efficiency, along with several physiological changes, including impaired immune function, increased oxidative stress, increased susceptibility to disease, and intestinal damage ().
Key Takeaways
- 01Heat stress leads to a decrease in feed intake and feed conversion efficiency, along with several physiological changes, including impaired immune function, increased oxidative stress, increased susceptibility to disease, and intestinal damage (). [Alqhtani Haifa Ali (2026)]
- 02This results in reduced nutrient absorption, increased mortality rates, and greater economic losses (). [Alqhtani Haifa Ali (2026)]
- 03From a sustainability perspective, heat stress exacerbates resource inefficiencies and feed utilization, leading to increased greenhouse gas emissions and nutrient waste, which threatens the long-term sustainability of poultry projects, particularly in hot climates (). [Alqhtani Haifa Ali (2026)]

The current Migaku evidence database contains 2 reusable source documents for Selenium Antioxidant Status Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove.
- Heat stress leads to a decrease in feed intake and feed conversion efficiency, along with several physiological changes, including impaired immune function, increased oxidative stress, increased susceptibility to disease, and intestinal damage (). [Alqhtani Haifa Ali (2026); evidence level 4]
- This results in reduced nutrient absorption, increased mortality rates, and greater economic losses (). [Alqhtani Haifa Ali (2026); evidence level 4]
- From a sustainability perspective, heat stress exacerbates resource inefficiencies and feed utilization, leading to increased greenhouse gas emissions and nutrient waste, which threatens the long-term sustainability of poultry projects, particularly in hot climates (). [Alqhtani Haifa Ali (2026); evidence level 4]

[Alqhtani Haifa Ali (2026); evidence level 4]
- Selenium supplementation significantly improved average daily gain, final body weight, and feed conversion ratio ( p 24 h), higher ultimate pH, and lower drip loss ( p < 0.05). [Yang X (2026); evidence level 4]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
