Zhou and Wang (2011), Bagheri et al, (2015), Mahmoud et al, (2016) and Bakhshalinejad et al, (2018) noticed higher body weight gain in chicken supplemented with nano selenium compared to other sources.…”

“…Under experimental conditions less favorable to chicken health, selenium supplementation was reported to be beneficial for chicken (Xu et al, 2015). It has been observed that the competition for zinc within the chicken microbiota plays a role in the effective colonization of C. jejuni (Gielda and DiRita, 2012).…”

“…Selenium can be added to chicken feed in the organic or inorganic form (Zoidis et al, 2014). It has been observed that selenium in-feed supplementation increases carcass weight, oxidative stress response, immune response and it appears to be most effective in limiting morbidity when the broilers are exposed to disease or environmental stress (Zhou and Wang, 2011; Chen et al, 2014; Markovic et al, 2014; Boostani et al, 2015; Xu et al, 2015; Sun et al, 2016). One interesting form of selenium that is commercially available is yeast grown in a media enriched with selenium.…”

Lack of Evidence That Selenium-Yeast Improves Chicken Health and Modulates the Caecal Microbiota in the Context of Colonization by Campylobacter jejuni

Faced with ever-increasing demand, the industrial production of food animals is under pressure to increase its production. In order to keep productivity, quality, and safety standards up while reducing the use of antibiotics, farmers are seeking new feed additives. In chicken production, one of these additives is selenium. This element is expected to confer some advantages in terms of animal health and productivity, but its impact on chicken intestinal microbiota as well as on the carriage of foodborne pathogens is unknown. In this study, chickens raised in a level 2 animal facility were fed or not 0.3 ppm of in-feed selenium-yeast until 35 days of age and were inoculated or not with the foodborne pathogen Campylobacter jejuni at the age of 14 days. At the end of the study, body weight, seric IgY, intestinal IgA, seric gluthatione peroxydase activity, the caecal microbiota (analyzed by MiSeq 16S rRNA gene sequencing), and C. jejuni caecal levels were analyzed. The experiment was completely replicated twice, with two independent batches of chickens. This study revealed that, for healthy chickens raised in very good hygienic conditions, selenium-yeast does not influence the bird’s body weight and lowers their seric gluthatione peroxidase activity as well as their intestinal IgA concentrations. Furthermore, selenium-yeast did not modify the caecal microbiota or the colonization of C. jejuni. The results also showed that C. jejuni colonization does not impact any of the measured chicken health parameters and only slightly impacts the caecal microbiota. This study also clearly illustrated the need for true biological replication (independent animal trials) when assessing the microbiota shifts associated with treatments as the chickens microbiotas clearly clustered according to study replicate.

“…Compared to the results obtained from in ovo injection, dietary supplementation of B-taxim over a period of 24 h was less effective. However, 0.50 mg selenium/kg feed alleviated the body weight reduction associated with necrotic enteritis, reduced intestinal lesions and increased antibody production against NetB-toxin (Xu et al, 2015).…”

“…Positive effects of selenium supplementations in amounts exceeding the nutritional requirements have been observed for coccidiosis, necrotic enteritis and avian pathogenic E. coli (APEC) in poultry, where supplemental selenium seems to increase disease resistance and/or alleviates symptoms associated with the disease (Larsen et al, 1997;Mahmoud and Edens, 2005;Wunderlich et al, 2014;Lee et al, 2014a;Lee et al, 2014b;Xu et al, 2015).…”

A B S T R A C TSelenium is an essential nutrient for poultry and pigs, and is important for a number of physiological processes including regulation and function of the immune system. Through its incorporation into selenoproteins, Se is involved in the regulation of oxidative stress, redox mechanisms, and other crucial cellular processes involved in innate and adaptive immune response.This review provides current knowledge on the mechanisms by which selenium can modulate the resilience to infectious diseases, and how this micronutrient can influence the capacity of the bird or the pig to maintain its productivity during an infectious challenge. In relation to the most frequent and economically important infectious diseases in poultry and pig production, the present paper considers the influence of different selenium sources (organic vs. inorganic Se) as well as dietary concentrations on the immune responses of poultry and pigs with major emphasis on the potential beneficial impact on animal resilience to common infectious diseases.
