This work was conducted to evaluate the effect of dietary organic selenium (OR-Se) supplementation on growth performance, carcass traits, nutrient digestibility, blood metabolites, and antioxidant capacity of broiler chicks that reared in a high temperature environment. A total number of 320 one-day old unsexed chicks (Cobb-500) were raised during summer season under temperature ranged between 29.9 to 33.3 °C. Birds were randomly assigned to four treatment groups of 80 chicks each, with four replicates each of 20 chicks, kept in floor pens. The 1 st group (T1) was fed basal diet, while the 2 nd , 3 rd and 4 th groups (T 2 , T 3 , and T 4) were fed diets supplemented with 0.3, 0.6 and 0.9 mg OR-Se/kg diet, respectively. The obtained results indicated that, groups supplemented with 0.6 and 0.9 mg OR-Se (T 3 and T 4) significantly improved growth parameters (body weight, body weight gain, feed conversion ratio), and nutrients digestibility. Also, these groups had higher (P< 0.05) carcass weight and lower (P< 0.05) abdominal fat. Besides, blood parameters including red blood cells, haemoglobin and haematocrit concentrations of chicks in these groups were clearly increased in comparison with chicks (T 2) or the control group (T 1). Furthermore, adding OR-Se to broiler diets statistically enhanced lipid profile, liver enzymes, kidney function, and antioxidant activity under high temperature environment. It could be concluded that dietary supplementation with OR-Se (0.6 and 0.9 mg/kg diet) had a positive effects on productive performance of broilers by improving growth performance, digestibility of nutrients, blood metabolites, and antioxidant capacity of broiler chickens practically under summer conditions compared to the others in the groups.

An experiment was designed to investigate the effects of dietary selenium on performance, carcass traits, blood biochemicals, tissues selenium deposition, antioxidant activity and immunoglobulin of broiler chicks. Total of 210 day old broilrer chicks were divided into seven dietary treatment groups with three replicates each. Control group (T 1) was fed with basal diet contain the recommended level of selenium of Arbor-Acres broiler chicks cataloge, as a source of inorganic selenium. Experimental groups; T 2 , T 3 and T 4 were given basal diet free of selenium, but supplemented with 0.1, 0.2 and 0.3 g selenium yeast/ kg diet, T 5 , T 6 and T 7 were fed basal diet free of Se and supplemented with 0.01, 0.02 and 0.03 g nano-selenium/ kg diet, respectively. Results showed that chicks fed diet supplemented with 0.03g nano-selenium/ kg diet (T 7) had significantly (P ≤ 0.05) the highest values of daily weight and improved feed conversion ratio compared to the other treatments which also recorded the least feed intake. Se-yeast or nano-selenium showed higher some carcass traits, liver meat of breast and thigh Se contents and high density lipoprotein, while low density lipoprotein, concentrations were significantly (P ≤ 0.05) decreased. Activity of glutathione peroxidase, in serum blood was significantly (P ≤ 0.05) increased by supplementation of 0.03 g nano-selenium/ kg diet compared to the control group and other treatments. Also, chicks fed diet supplemented with 0.03 g nano-selenium/ kg diet had the highest livability rate (98%) and the best European efficiency rate (443.5%) but it was less economically efficient and relatively economic efficiency may have been due to the high price of nanoselenium at the present time compared to organic selenium. So, the obtained results in the present study encouraging and indicated that 0.3 g selenium yeast/ kg diet (T 4) can be used in broiler chicken diets to get best economic efficiency and higher relative economic efficiency. It could be concluded that addition of organic and nano-selenium in broiler diets positively affects production performance and various parameters of broilers health.

The effects of organic selenium (Se) supplementation of diets for broiler chickens were evaluated in the present study. Broiler diets had average background Se concentrations of 0.36 mg/kg Se (control diet) and were supplemented with two organic Se sources, namely BiOnyc® Tor-Sel (selenohomolanthionine = SH) and Alltech’s Sel PlexTM (selenomethionine = SM); their addition increased dietary selenium concentrations by an average of 0.57 mg/kg Se. Their effects on growth performance, nutrient utilisation and oxidative status of broiler chickens were determined. Growth performance was very similar across all dietary treatments; in contrast, significant differences in nutrient utilisation were observed. The N-corrected apparent metabolisable energy value for the control group (14.14 MJ/kg) and SH (14.15 MJ/kg) diet was significantly (P < 0.01) higher than that for the SM (13.64 MJ/kg) diet. Alternatively, N retention with the SM (68.4%) diet was significantly (P < 0.005) higher tha...
Impact of Selenium Sources on Productive and Physiological Performance of Broilers
Egyptian Poultry Science Journal, 2020
A total number of 210 unsexed (Arbor Acres) broiler chicks at 7 day of age were used to investigate the effects of different sources of Selenium i.e. inorganic (Sodium selenite (SS), organic (Saccharomyces cerevisiae with Se and Zn / Se-Methionine/Se-Glycine/ Se-Yeast and Saccharomyces cerevisiae with Se) on the productive performance, blood hematological and biochemical constituents and immune response of broiler chicks. Experimental chicks were randomly divided into seven dietary treatments with six replicate cages per treatment, five chicks each. The first group was fed the basal diet without supplementation (control); while the 2 nd , 3 rd , 4 th , 5 th , 6 th and 7 th groups were fed basal diet supplemented with 100 ppm/kg diet of the above mentioned Se sources, respectively. Results showed that chicks fed the basal diet supplemented with different sources of Se had significantly better BW, BWG and FCR compared with control group. Organic Se supplementation improved growth performance of broilers compared with the inorganic one. Supplementation of different Se sources decreased serum levels of cholesterol and LDL, whereas RBCs count, hemoglobin, PCV, glucose, globulin, thyroid hormones, immune response (IgA-IgM, IgG), and antioxidant enzymes activity were significantly increased compared with the control. In conclusion, Se supplementation improved the growth performance, immune response and physiological status of broiler chickens. Broilers fed organic Sesupplemented diets had better growth performance and immune response than those fed inorganic selenium.

This study was conducted to investigate the effects of different sources of dietary selenium (Se) supplementation on growth performance, meat quality, Se deposition, and antioxidant property in broilers. A total of 600 one-day-old Ross 308 broilers with an average body weight (BW) of 44.30 ± 0.49 g were randomly allotted to three treatments, each of which included five replicates of 40 birds. These three groups received the same basal diet containing 0.04 mg Se/kg, supplemented with 0.15 mg Se/kg from sodium selenite (SS) or from l-selenomethionine (l-Se-methionine (Met)) or from d-selenomethionine (d-Se-Met). The experiment lasted 42 days. Both Se source and time significantly influenced (p < 0.01) drip loss of breast muscle. Supplementation with l-Se-Met and d-Se-Met were more effective (p < 0.05) in decreasing drip loss than SS. Besides, the pH value of breast muscle was also significantly influenced (p < 0.05) by time. The SS-supplemented diet increased more (p < 0.05) liver, kidney, and pancreas glutathione peroxidase (GSH-Px) activities than the d-Se-Met-supplemented diet. In addition, l-Se-Met increased more (p < 0.01) liver and pancreas GSH-Px activities than d-Se-Met. The antioxidant status was greatly improved in broilers of l-Se-Met-treated group in comparison with the SS-treated group and was illuminated by the increased glutathione (GSH) concentration in serum, liver, and breast muscle (p < 0.05); superoxide dismutase (SOD) activity in liver (p < 0.01); total antioxidant capability (T-AOC) in kidney, pancreas, and breast muscle (p < 0.05) and decreased malondialdehyde (MDA) concentration in kidney and breast muscle (p < 0.05) of broilers. Besides, supplementation with d-Se-Met was more effective (p < 0.01) in increasing serum GSH concentration and decreasing breast muscle MDA concentration than SS. l-Selenomethionine supplementation significantly increased GSH concentration in liver and breast muscle (p < 0.05); SOD activity in liver (p < 0.01); and T-AOC in liver, pancreas, and breast muscle (p < 0.05) of broilers, compared with broilers fed d-Se-Met diet. The addition of l-Se-Met and d-Se-Met increased (p < 0.01) Se concentration in serum and different organs studied of broilers in comparision with broilers fed SS diet. Therefore, dietary l-Se-Met and d-Se-Met supplementation could improve antioxidant capability and Se deposition in serum and tissues and reduce drip loss of breast muscle in broilers compared with SS. Besides, l-Se-Met is more effective than d-Se-Met in improving antioxidant status in broilers.
BMC Veterinary Research
Background Selenium (Se) has been recognized as an essential micronutrient for nearly all forms of life. In recent decades, broiler responses to dietary Se supplemental levels and sources have received considerable attention. On environmental grounds, organic trace mineral utilization in practical broiler feeds has been defended due to its higher bioavailability. In such feeds, trace minerals are provided simultaneously in the same supplement as inorganic salts or organic chelates, a fact commonly ignored in assays conducted to validate organic trace mineral sources. The current assay aimed to investigate growth and biochemical responses, as well as Se retention of growing chicks fed diets supplemented with organic and inorganic Se levels and where the trace minerals (zinc, copper, manganese, and iron) were provided as organic chelates or inorganic salts according to Se source assessed. In so doing, a 2 × 5 factorial arrangement was used to investigate the effects of sodium selenite...

An experiment was conducted to determine the effect of supplementing various concentrations (0, 100, 200, 300, or 400 g/kg diet) of organic Se on growth performance, carcass traits, oxidative stress, and immune responses in commercial broiler chickens reared in open-sided poultry house under tropical climatic conditions. Each diet was fed ad libitum to eight replicates consisting of six birds in each pen from 1 to 42 d of age. Body weight gain and feed efficiency, and relative weight of liver, abdominal fat and ready to cook yields were not affected (p>0.05) by organic Se supplementation to broiler diets. Lipid peroxidation in plasma decreased, while activities of glutathione peroxidase and glutathione reductase in plasma increased (p<0.01) linearly with Se concentration in diet. The ratios between heterophyls and lymphocytes and relative weight of lymphoid organs (bursa, spleen, and thymus), and antibody production to Newcastle disease vaccination were not affected (p>0.05) by Se supplementation to broiler diets. However, the cellmediated immunity (lymphocyte proliferation ratio) increased (p<0.01) linearly with dietary Se concentration. The results of the present study indicate that the supplementation of Se did not influence body weight and feed efficiency. However, supplementation of Se increased antioxidant status and lymphocyte proliferation in broiler chickens.

The vital role of selenium in various metabolic reactions and its role as a component of antioxidant enzymes has awaken research interest in livestock production. Its influence on animal fertility, production and disease prevention is subject for on-going research. Deficiency of selenium have serious negative effect on animal skeletal and cardiac muscles which will in turn reduce growth, and there is dearth of information on its effect on growth performance, haematological indices and carcass characteristics of broiler chicken, the reason for this study. An experiment was carried out to investigate the effect of selenium on growth performance, haematological indices, carcass characteristics and sensory properties of broiler birds. Atotal of 120, one-day-old chicks were randomly assigned to four treatments in a completely randomized design and were further divided into three replicates with 10birds per replicate. Selenium was administered orally through their drinking water in three ...

The experiment was aimed at investigating the antioxidant effect of selenium on serum biochemistry, hormones, carcass and jejunum morphology of broiler chickens. Two hundred and fifty-six broiler chickens were allotted to four treatments with iso-caloric diets supplemented with selenium (0, 0.1, 0.2 and 0.3) and replicated four times in a completely randomized design. Data collected were analyzed using SAS package and means were compared using Tukey's procedure. Broilers fed diets supplemented with the control and 0.1 mgSe/kg had higher (p<0.05) cholesterol. SOD was higher (p<0.05) in birds fed 0.2 and 0.3 mgSe/kg, catalase was elevated (p<0.05) in broilers fed the control diet and 0.3 mg selenium supplemented diet. Serum phosphorus was higher (p<0.05) in broilers fed 0.2 mgSe/kg. Cortisol was down regulated (p<0.05) in broilers fed the control diet, 0.1 and 0.2 mgSe/kg, thyroxine was similar (p>0.05) among the groups. Higher (p<0.05) dressing percentage and back weight was recorded in broilers fed 0.3 mg selenium supplemented diet and thigh weight was higher (p<0.05) in the control group. Wing weight was higher (p<0.05) in broilers fed the control and 0.3 mgSe/kg while organ measurement was similar (p>0.05) in all the groups. Jejunum morphology was similar (p>0.05) in all groups except for villus height/crypt depth ratio which was higher (p<0.05) in broilers fed the control, 0.1 and 0.2 mgSe/kg diet. It is concluded that supplementation of selenium upto 0.2 mg/kg diet has potent antioxidant effect on broiler chickens.

Two sources of selenium are commonly used in poultry nutrition, the organic and the inorganic forms. This study was carried out to investigate the comparative effect of Sasso broiler breeder feed supplemented with sodium selenite (SS) and selenomethionine (SM) on the zootechnical performance, hematology, and hatching process of chickens. A total of 120 female broiler breeders and 12 roosters of Sasso strain at 47 weeks were equally assigned to three treatments with four replicates per each, including 10 breeders crossed with 1 rooster. The treatment groups were broiler breeders fed a basal diet without selenium supplementation (control), chickens fed the basal diet supplemented with SS, and breeders fed the basal diet supplemented with SM. The inclusion level of each selenium was 0.2 ppm. The collected data included feed intake and egg weight during 8 weeks. In the end, blood samples were collected for hematological investigations. A total of 150 hatching eggs were collected from each treatment. After recording their weight, the eggs were incubated at adequate temperature and relative humidity. On day 18 of incubation, the eggs were weight again, candled, and transferred into the hatcher. Each egg was individually checked every 3 hours during the last 3 days of incubation for hatching events determination. The results showed that breeders fed SM had the lowest feed conversion ratio. There was an increase in the majority of blood parameters in breeders fed SM, compared to other treatments. The lowest duration of the hatching events was observed with breeders fed SM, and consequently, they had the best hatching rate but without any significant difference in the chicks' quality and their weight of internal organs at the hatch. In conclusion, this study demonstrated that using selenium is beneficial, especially in the organic form, which appeared to be more efficient, compared to the inorganic form.
