“…The results of the present study showed that excess Se supplementation resulted in a significant increase in plasma Se levels and blood GPx activity, in good agreement with our previous findings in broilers supplemented with 0.5 ppm Se as zinc L-selenomethionine complex (Chadio et al, 2015). More interestingly elevated GPx activity was also detected in broilers supplemented with vitamin E alone or in combination with Se.…”

“…Previously, data showed that excess Se supplementation did not alter thyroid hormone levels, while it increased liver antioxidant enzymes activity (Chadio et al, 2015). Given the role of vitamin E in protecting the stability of microsomal membrane in which ID-I exists Yue et al, 1998) the aim of the present study was to investigate if concomitant supplementation of additional vitamin E and Se could influence thyroid hormone metabolism and antioxidant enzyme activity in broilers.…”

“…Such results are similar to those of Selim et al (2015), Rama Rao et al (2016) and Bakhshalinejad et al (2018), who found that adding supplemental Se improved FI and BWG in different broiler strains. In contrast, other researchers found that the addition of Se treatment from various sources had no significant effects on BWG, FI and FCR of broilers (Cai et al 2012;Briens et al 2013;Habibian et al 2014;Chadio et al 2015). These different results may likely be a function of differences in Se content of the feeding stuffs.…”

Although selenium (Se) supplementation is a common practice in poultry, the best source and level has not been established yet. Thus, a 42-day experiment involving diets with three levels (0.1, 0.2 and 0.5 mg/kg) of supplemental Se from sodium selenite (SS), selenised yeast (SY) and nanoelemental Se (SN) was conducted to evaluate the possible differential responses of broiler chickens to inorganic, organic and nano Se sources relative to a control diet. Throughout the experiment, broilers receiving Se supplements had higher feed intake, body weight gain (BWG) and survival rate than the control. Broilers fed dietary SY or SN had improved BWG compared with those fed the SS-supplemented diets. Broilers treated with Se supplementation had increased serum glutathione peroxidase (GPx) and thioredoxin reductase (TrxR) activities and produced higher antibody responses to avian influenza virus (AIV) and sheep red blood cell (SRBC) versus the control. These effects were enhanced with increasing Se addition, except for GPx that responded equally to all supplemental Se levels. Also, broilers receiving supplementary SY or SN exhibited higher anti-AIV and anti-SRBC titres along with more elevated serum Se, TrxR activity and total antioxidant capacity compared with those receiving SS. At the same time, SN had the most increasing effect on anti-SRBC titre. To conclude, diet supplementation with 0.5 mg/kg of Se in the form of SY or SN was capable of meeting the Se demands of broiler chickens for optimum growth and antioxidant capability, while SN seemed to be the most effective Se source in enhancing immunity. HIGHLIGHTS Diet supplementation with SN and SY, especially at 0.5 mg/kg diet, improved broiler performance and carcase quality of chickens compared with SS. SY and SN showed more favourable effects on oxidative status and immunocompetence. The best anti-SRBC titre was observed with SN.

“…However, Chadio et al. () reported that the plasma T 3 contents in broilers were not affected by supplementation of 0.3 mg Se/kg Zinc l ‐selenomethionine with the basal diet containing 0.289 mg Se/kg. The differences between our results and those of others may be attributed to the various Se sources and levels adopted in those trials.…”

This trial was conducted in a 2 × 3 + 1 factorial arrangement based on a completely randomized design to evaluate the effects of different dl-selenomethionine (dl-Se-Met) and sodium selenite (SS) levels on growth performance, immune functions and serum thyroid hormones concentrations in broilers. A total of 840 Ross 308 broilers (7 days old) were allocated by body weight to seven treatments (three replicates of 40 birds each treatment) including (1) basal diet (containing 0.04 mg of selenium (Se)/kg; control) without supplementary Se; (2, 3 and 4) basal diet + 0.05, 0.15 or 0.25 mg/kg Se as SS; (5, 6 and 7) basal diet + 0.05, 0.15 or 0.25 mg/kg Se as dl-Se-Met. The experiment lasted 42 days. The results revealed that dietary Se supplementation improved (p < 0.05) average daily gain, feed efficiency, immune organ index, serum immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM) and triiodothyronine (T3 ) concentrations and decreased (p < 0.01) thyroxine (T4 )/T3 ratio in serum compared with the control. Broilers receiving the dl-Se-Met-supplemented diets had higher (p < 0.05) feed efficiency, thymus index, the amounts of IgA, IgG, IgM and T3 as well as lower (p < 0.05) serum T4 concentrations and T4 /T3 ratio than those consuming the SS-supplemented diets. Serum IgA and IgM levels of broilers fed 0.15 mg Se/kg were significantly higher (p < 0.05) than those of broilers fed 0.05 or 0.25 mg Se/kg. In summary, we concluded that dl-Se-Met is more effective than SS in increasing immunity and promoting conversion of T4 to T3 , thus providing an effective way to improve the growth performance of broilers. Besides, based on a consideration of all experiment indices, 0.15 mg Se/kg was suggested to be the optimal level of Se supplementation under the conditions of this study.
