“…These observations are in line with those of Van Ryssen et al (1989) in sheep, Falkowska et al (2000) and Gunter et al (2003) in cows, Ortman and Pehrson (1999) in dairy cows and Pechova et al (2012) in goats, who reported higher whole blood Se concentrations in animals supplemented with organic Se compared to those administered diets of a comparable Se content where sodium selenite was the source of supplementary Se.…”

The experiment was conducted to evaluate the effect of feeding a diet supplemented with different forms of selenium on the rumen fluid, blood and serum enzyme activity and osmotic fragility of red blood cells in sheep. The experiment was carried out on 18 sheep of the Valashka breed at the age of 18 months, divided into 3 groups. The first group was given basal diet (BD) with a Se content of 0.17 mg/kg of dry matter (DM). The second group received BD supplemented with 0.4 mg Se/kg of (DM) in the form of sodium selenite. The third group received BD supplemented with 0.4 mg Se/kg of (DM) in the form of Se-yeast extract. Duration of the trial was 12 weeks. Selenium concentration in blood and total rumen fluid were elevated in both supplemented groups with the highest values in Se-yeast-treated sheep. Blood glutathione peroxidase (GPx) activity was significantly increased, regardless of the source of selenium. Osmotic resistance of red blood cells was not affected by selenium supplementation. The results indicate that feeding a diet supplemented with selenium from Se-yeast or selenite improved selenium status in blood and total rumen fluid. Selenium from sodium selenite was as effective as selenium from Se-yeast in the availability of selenium for the blood GPx activity. The effect of selenium supplementation on the ruminal enzyme activity depends on the selenium form; GGT and GDH were significantly higher in the Se-yeast supplement group, AST and ALP were significantly higher in the selenite supplement group. Rumen, blood enzymes, ruminantSelenium is an essential trace element which plays an important role in the antioxidative, reproductive, endocrine and immune systems of species.In most European Union countries the natural Se content in feed is only 0.03-0.12 mg/kg of dry matter (Pappas et al. 2008). The intake of such feeds can result in serious Se deficiencies and health problems especially in young growing and highly producing animals.For this reason commercial animal feeds are routinely supplemented with various Se sources up to the maximum European Union authorized total Se content of 0.5 mg/kg of feed.Currently, sodium selenite (Na 2 SeO 3 ) and sodium selenate (Na 2 SeO 4 ) as inorganic and selenium-enriched yeast (Se-yeast) as organic Se are principal selenium supplements of animal feed.It is established that selenocompounds from dietary inorganic and organic Se sources follow different metabolic pathways (Qin et al. 2007;Wang et al. 2009). Intestinal absorption of Se is much lower in ruminants than in nonruminants. For selenite, the absorption is 79% and 80% in poultry and swine, respectively, whereas only 29% in sheep. For selenomethionine and selenate the absorption is higher than 90% in monogastrics and poultry. Low absorption of selenium in ruminants is believed to result from reduction of dietary selenium (selenite and selenate) to unsoluble forms such as elemental selenium or selenides in the rumen environment (Mehdi et al. 2013).

“…Our findings demonstrated insignificant alterations of serum triacylglycerol, HDL, LDL levels in supplemented ewes compared with the control group. These findings were in line with that recorded by NEMAT (2015) and being away from that reported by others (FALKOWSKA et al 2000;SHERIEF et al, 2019).…”

The present study aimed at evaluating the influence of administration of vitamin E and selenium (VE/Se) on the gene expression pattern of some immune-metabolic variables as well as the oxidative stress markers in Barki ewes during the transition period. Sixty clinically healthy Barki ewes were studied. Two weeks prior to lambing, the investigated ewes were allocated into three equal-sized groups and assigned to receive one of the following supplements: (G1) received sterile saline solution (0.9 % NaCl) and considered as a control group; (G2) received a single intramuscular injection of VE/Se at a dose of 6.66 IU/kg BW VE, and 0.133 mg/kg BW Se; while G3 received the same dose of VE/Se but repeated at the time of lambing. Blood samples were collected from each ewe at the following time points: two weeks before lambing (-14), at time of lambing (0), and two weeks following the date of lambing (+14), for molecular and biochemical analyses. Our findings demonstrated that VE/Se supplementation had improved the gene expression of interleukin (IL)5, IL6, toll-like receptor 4 (TLR4), toll interacting rotein (Tollip), superoxide dismutase 1 (SOD1), catalase (CAT), acetyl-CoA carboxylase 1 (ACACA), fatty Acid Synthase (FASN) and stearoyl-CoA desaturase-1(SCD). A moderate degree of negative energy balance was seen at the time of lambing and two weeks later as evidenced by the values of metabolic variables including glucose, non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHBA), and cholesterol levels. A repeated dose VE/Se supplementation provoked a significant effect on glucose, total cholesterol, NEFA, malondialdehyde (MDA), total anti-oxidant 674

“…Also, the insignificant effect of treatment with Se or Se+Vit. E on triglycerides was in accordance with the previous work on cows, sheep, lambs or goats by Shinde et al (2009), Soliman et al (2012), Falkowska et al (2000, Antunović et al (2014) andZiaei, (2015) who reported that selenium supplementation had no significant effect on blood triglycerides.…”

The present study was carried out at Sanad Company for Animal Production, Damietta governorate, Egypt, during the period from June to September 2013 (summer). Twenty healthy Holstein dairy cows, free from diseases, of similar age (3 years old) and average body weight (500±25kg) and (80±10 days in milk) were used in the present study. All animals were at the second season of lactation in summer season. Animals were randomly assigned into four experimental groups (each of 5 animals): G1 was intramuscular injected at biweekly intervals with 10 ml saline solution and served as a control group, G2 was intramuscular injected every two weeks with 10 ml viteselen, G3 was intramuscular injected every two weeks with 20 ml viteselen and G4 was supplemented in their daily ration with 3mg, organic Selenium (O-Se)/ kg DMI. Productive (milk: production, fat, protein, lactose, total solids, solids non-fat and somatic cell count), blood chemical (plasma: Glutathione peroxides, proteins, urea, ALT, AST, glucose, cholesterol and triglycerides) and physiological parameters (rectal temperature and respiration rate) were measured at the start and the end of 60 days experimental period.Results indicated that Se treatment either in inorganic or in organic forms with or without vit. E. did not affect significantly all productive, blood chemistry and physiological parameters expect somatic cell count and Glutathione peroxides. It can be concluded that, the main effect of Se treatment is the reduction of somatic cell count due to its effect on immunity; meanwhile, Se had no role in alleviation of heat stress under summer conditions at Northern region (Delta) of Egypt.
