“…Similar results have been reported by Cao et al (2001) and Perić et al (2009). The reduction in skin tearing for the OTM group may be related to improved feathering (Edens et al, 2000) and to a higher availability of organic Zn (Rossi et al, 2007) and Cu (Zhao et al, 2010) which influences skin quality. With this improvement in skin integrity, economic losses due to downgrades at slaughter could be reduced (Rossi et al, 2007).…”

“…Cao et al (2001) similarly didn't see any benefit on meat lightness with the use of organic Se, in spite of the suggested pro-oxidant effect of selenite. The higher bioavailability of organic selenium (Edens et al, 2000) was the most probable reason for the improvement in breast meat colour seen in the OTM group. In one of the available studies comparing meat colour of birds fed with different sources of Se, Cao et al (2001) reported that, although this was not significant, meat colour in birds fed organic Se was redder than those given an inorganic source.…”

“…Improved feathering indicated that OTM were used more efficiently by the birds, particularly Se (Edens et al, 2000), Zn and Cu (Scheideler, 2008). Similar results have been reported by Cao et al (2001) and Perić et al (2009).…”

“…OTM allow lower dietary inclusion and cause less environmental pollution (Petrovič et al, 2010). Feeding OTM has been shown to result in a similar level of performance (Perić et al, 2006;Petrovič et al, 2010), reduce mortality due to sudden death syndrome (Roch et al, 2000), increase skin strength (Rossi et al, 2007), improve feathering (Perić et al, 2006, Perić et al, 2009, reduce skin lesions (Edens et al, 2000) and improve carcass quality (Rossi et al, 2007) and meat stability by reducing drip loss and improving meat colour (Cao et al, 2001;Hess et al, 2007). The increased resistance of the skin, together with greater protection afforded by improved feathering, leads to a reduction in tears and damage (Edens et al, 2001;Peric et al, 2009), reducing carcass downgrades (Rossi et al, 2007).…”

The aim of this study was to compare the performance and carcass quality of broilers fed diets containing either a commercial inorganic mineral premix (control) or organic trace minerals (OTM) (Sel-Plex ® (Se) and Bioplex ® copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe)) in a commercial environment. Four identical houses with a total of 119,500 mixed-sex broiler chickens were used (two treatments × two replicates). Birds were fed identical corn/soybean based rations differing only in mineral form and levels. The inorganic treatment (control) provided Cu, Zn, Fe, Mn and Se at levels of 8, 44, 55, 66 and 0.2 ppm, respectively. The OTM contained 5.5, 22, 5.5, 22 and 0.3 ppm of Cu, Zn, Fe, Mn and Se respectively. Growth and feed conversion during the 35-day trial were not influenced (P > 0.05) by treatments. Over the entire trial period and during the first week of production, birds showed significantly lower (P < 0.05) mortality with the OTM treatment. Between 14 and 31 days, sudden death syndrome was lower (P < 0.05) with the OTM diet. OTM improved feathering at 21 days of age (P < 0.001) and lowered carcass skin tearing (P < 0.05). There was no effect of OTM on carcass yield, breast meat pH, drip loss or on meat colour (L* and b* values). However, birds fed organic minerals had redder breast meat (a*) (P < 0.05) on days three and five after slaughter. The results showed that, under commercial conditions, using lower levels of OTM (except Se) in feed relative to inorganic controls can maintain broiler performance.

“…The results of this study revealed that dietary supplementation of SS did not have any impact on the final BW of squabs, in agreement with the findings of Yoon et al (2007) and Wang and Xu (2008). Previous studies showed that supplemental Se did not affect BW, regardless of the feeding duration, that Edens et al (2000) fed broilers with basal diets containing 0.10 or 0.30 ppm SS for 42 days, Choct et al (2004) fed broilers with basal diets supplemented with 0.10 or 0.25 mg/kg SS for 38 days, and Dlouh a et al (2008) fed broilers with basal diets supplemented with 0.3 mg/kg SS for 42 days. The different letters indicate the difference were significant (adjacent for P < 0.05; interval for P < 0.001).…”

A feeding experiment was carried out to examine the effect of dietary sodium selenite (SS) supplementation on pigeon squabs. A total of 864 paired pigeons were randomly and equally distributed into four groups with three replicates. Each group was given a basal diet either unsupplemented (T1) or supplemented with 0.5, 1.0, or 1.5 mg/kg of SS in feed (T2-T4). Diet had no significant effect on the final body weight of squabs (P > 0.05). However, during days 8-14, body weight gain (BWG) in SS supplemented groups was lower than the control group (P < 0.05), while BWG was higher than controls from days 15-21 (P < 0.05). Squabs fed the basal diet without SS supplementation displayed lower selenium content in chest and leg muscle (P < 0.05). Glutathione peroxidase 4 (GPx4) mRNA levels were lower in liver, ovary and testis tissue in controls (P < 0.05), while growth hormone (GH) mRNA levels in liver were higher in controls (P < 0.05). These results suggest dietary SS supplementation had potential effect on growth performance during the later growth period (days 15-21). Furthermore, dietary SS supplementation increased the selenium content in muscle and affected the expression of GPx4 and GH. HIGHLIGHTS The dietary selenium supplementation affected the body weight gain of the squabs. Increasing selenium supplementation in diet improved the selenium content in muscle. Increasing selenium supplementation in diet affected the expression of GPx4 and GH.

Effects of dietary selenium and vitamin E on immune response and biological blood parameters of broilers reared under thermoneutral or heat stress conditions

et al. 2013

A study was conducted using 360 broiler chickens to evaluate the effects of dietary vitamin E (0, 125 and 250 mg/kg), selenium (Se, 0, 0.5 and 1 mg/kg), or their different combinations on immune response and blood biological parameters of broilers raised under either thermoneutral (TN, 23.9 °C constant) or heat stress (HS, 23.9 to 37 °C cycling) conditions. Humoral immunity was assessed by intravenous injection of 7% sheep red blood cell (SRBC) followed by evaluation of serum for antibody titers in primary and secondary responses. Heterophil to lymphocyte (H/L) ratio also determined as an indicator of stress. Furthermore, at the end of the experiment, birds were bled for determination of some biological parameters. There was a significant reduction in body weight and feed intake, but the feed conversion ratio increased when the birds were exposed to HS (P<0.05). Body weight and feed intake were not influenced significantly by dietary vitamin E and Se (P>0.05), whereas feed conversion was improved significantly by 125 mg/kg vitamin E (P<0.05). The liver and lymphoid organ weights as well as IgM and IgG, antibody titers for primary and secondary antibody responses to SRBC were reduced significantly under HS (P<0.05). Heat stress also resulted in a significant increase in H/L ratio (P<0.05). Dietary vitamin E resulted in improvement of primary and secondary antibody responses both in TN and HS broilers (P<0.05). The HS birds also showed an improved antibody titer in secondary response with high concentration of Se (P<0.05). Vitamin E and Se had interactive effects on anti-SRBC titers; however, no consistent differences were found between dietary levels during the study. The H/L ratio decreased by feeding vitamin E at both levels either under HS or TN conditions (P< 0.05). The serum concentrations of glucose, triglycerides, total cholesterol, and LDL-cholesterol were increased but serum HDL-cholesterol decreased in HS broilers (P<0.05).
