The use of different selenium sources and vitamin e levels as a strategy to support the performance of broilers raised in a hot climate.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Broilers raised in tropical environments face significant oxidative stress due to heat, which can impair performance. Vitamin E and selenium (Se) are key nutrients supporting antioxidant defenses and are commonly supplemented in feed. This study evaluated the effects of two selenium sources-sodium selenite (SS) and hydroxy‑selenomethionine (OH-SeMet)-combined with standard or reduced vitamin E levels on broiler performance. A total of 800 male broilers were assigned to a 2 × 2 factorial design. Results demonstrated that OH-SeMet improved growth and feed efficiency compared to SS, regardless of vitamin E level, while reduced vitamin E impaired early growth but not overall performance. The combination of OH-SeMet with standard vitamin E provided the best feed conversion ratio at 44 days. These findings highlight the benefits of using OH-SeMet with adequate vitamin E supplementation to enhance broiler resilience to heat stress, offering a practical strategy for improving production efficiency in tropical commercial operations.
