and quality of young growing Belgian Blue bulls offered a fattening diet with selenium enriched cereals. Can. J. Anim. Sci. 95: 465Á473. The objective of this study was to evaluate the effects of selenium (Se) enrichment of cereals on the performance of Belgian Blue bulls, meat quality and chemical composition. Twenty-three bulls were used in the present study. Twelve bulls were offered a control diet containing Se at a basal concentration of 58 mg kg(1 of dry matter (DM) and the other 11 bulls were given a diet containing 173 mg kg(1 DM of Se by means of Se-enriched spelt and barley. The Se enrichment of the diet did not affect the growth performance, the slaughter data or meat quality (P0.05). There were no effects of Se on tenderness, oxidative rancidity and water losses. However, there were some effects of Se enrichment on the meat chemical composition. The ether extract was decreased from 2.1 to 1.7% DM (P B0.05). There was also significant Se enrichment (PB0.001) in the longissimus thoracis muscle (177 vs. 477 ng g(1 DM) and organs: liver (474 vs. 1126 ng g (1 DM) and kidney (4956 vs. 5655 ng g(1 DM), Under such conditions, the human consumption of a piece of such meat or liver can provide a large part of the recommended daily Se intake, estimated between 30 and 57%.

“…Similarly, Wang et al () observed that DM intake was unchanged, but milk yield increased with 0.3 mg/kg DM of Se as Se yeast addition in dairy cows. Netto et al () reported an improved growth performance and feed efficiency with a high level of Se (2 mg Se/kg DM) addition in bulls. The observed increase in nutrient digestibility was associated with the increased ruminal microbial population and enzyme activity.…”

“…Selenium (Se), as a component of glutathione peroxidase, plays a major role in cell antioxidant system (NRC, ; Surai, ). Recent studies found that daily weight gain and feed efficiency in bulls (Netto et al, ), milk production (Wang et al, ) and activity of blood glutathione peroxidase and superoxide dismutase (Sun et al, ) in dairy cows increased with dietary Se addition. Literature demonstrated that ruminal microbes incorporate Se from the diet to form their protein and cell wall component (Hidiroglou, Heaney, & Jenkins, ), and the resistance of cell membrane against oxidative damage was improved with Se addition (Cobanova et al, ; Mihalikova et al, ).…”

Researches on sodium selenite (SS) mainly focus on production performance and rumen fermentation in ruminants, and the influence of dietary Se addition on ruminal microbial population and enzyme activity in dairy bulls is scarce. This study mainly evaluated the effects of SS on ruminal fermentation, microflora and urinary excretion of purine derivatives (PD) in dairy bulls. Eight ruminally cannulated dairy bulls were used in a replicated 4 × 4 Latin square design. Treatments were control, low SS (LSS), medium SS (MSS) and high SS (HSS) with 0, 0.1, 0.3 and 0.5 mg/kg of selenium (Se) from SS in dietary dry matter (DM), respectively. The supplement of SS (1.0 g/kg of Se) was mixed into the first third of the daily ration. Bulls were fed a total mixed ration with corn silage to concentrate ratio of 50:50 on a DM basis. Dry matter intake was not affected, average daily gain linearly increased, while feed conversion ratio quadratically decreased with increasing Se addition. The linearly increased digestibility of DM, organic matter, crude protein, ether extract, neutral detergent fibre and acid detergent fibre was observed. Both ruminal pH and ammonia‐N concentration linearly decreased, whereas total volatile fatty acid concentration linearly increased. A lower acetate to propionate ratio was observed due to the unchanged acetate proportion and increased propionate proportion. Activity of cellobiase, xylanase, pectinase, α‐amylase and protease, populations of total bacteria, fungi, protozoa, Ruminococcus (R.) albus, R. flavefaciens, Fibrobacter succinogenes, Butyrivibrio fibrisolvens and Ruminobacter amylophilus as well as urinary total PD excretion linearly increased, whereas populations of total methanogens and Prevotella ruminicola linearly decreased. The data indicated that dietary Se addition stimulated ruminal microbial growth and enzyme activity, and resulting in the increased nutrient digestion and growth performance, and the optimum supplementary dose of Se was 0.3 mg/kg dietary DM from SS in dairy bulls.

“…However, in the present study, Se was not deficient in either treatment, with there being no impact on animal performance, carcass weight or conformation, although the Selage lambs were slightly fatter at slaughter and had a greater body condition score during the study. The literature on the influence of Se on carcass quality and lipid deposition is inconclusive due to the variation in the form of Se and supplementation rate, with some studies in cattle reporting no effect (Juniper et al 2008;Taylor et al 2008) and others reporting a decrease in lipids (Netto et al 2014;Mehdi et al 2015). Reports on carcass quality in lambs supplemented with nano-Se are, to the best of the authors' knowledge, not available; however, a study in pigs supplemented with Se-enriched LAB found no difference in carcass parameters from those supplemented with sodium selenite or Se-enriched yeast (Svoboda et al 2009).…”

The potential of silage lactic acid bacteria-derived nano-selenium as a dietary supplement in sheep

Context Selenium (Se) is a trace element essential for cellular function in animals as a component of the enzymes glutathione peroxidase and iodothyronine-5-deiodinase. In many parts of Europe, Se is often deficient in livestock diets due to the low Se status of soil. Supplementation of diets with selenised yeast (predominately as seleno-methionine) or inorganic sodium selenite is common practice in most livestock systems, including ruminants. Lactic acid bacteria have been shown to convert inorganic Se into predominantly elemental nano-Se, which has been used recently in human pro-biotics as a less toxic form of Se. Therefore, silage lactic acid bacteria may provide a supplementation route of bioavailable nano-Se for ruminants. Aim Here, we report on the effect of feeding inoculated silage enriched with a supra-nutritional level of nano-Se (Selage) versus control inoculated silage (Silage) on the Se status of finishing lambs and their products, followed by a second study where blood parameters were investigated in ewes. Methods In the first study, 40 Charollais × Suffolk lambs (42 ± 1.7 kg) were paired according to weight and sex, then allocated to the two treatments for 8 or 10 weeks. Uptake of Se into wool was temporally assessed, as well as excretion of Se into faeces. Selenium concentrations in blood and muscle, carcass characteristics and meat quality are reported postmortem. In the second study, individually penned Suffolk × Mule ewes (n = 12; 76 ± 4.5 kg) were offered the same diets as in the first study. Blood parameters were assessed at the start and after 6 weeks, with intake and excretion into faeces and urine assessed temporally throughout the study. Key results In the first study, dry-matter (DM) intake was similar in both treatment groups, at 0.8 ± 0.03 kg/day, but Se concentrations of the diets were significantly different, resulting in intakes of ~0.14 and 1.60 mg/day on the Silage and Selage diets, respectively. This was reflected in higher Se concentrations in faeces (0.4 vs 2.0 mg/kg DM; P < 0.001), wool (0.11 vs 0.25 mg/kg DM; P < 0.001), blood (0.19 vs 0.46 mg/L; P < 0.001) and muscle (0.31 vs 0.41 mg/kg: P < 0.01) on the Selage than on the Silage diet. Colour (chroma) shelf life of the meat was significantly higher on the Selage treatment (8.05 vs 9.2 days; P < 0.05). In the second trial, for ewes fed Selage, blood seleno-methionine increased from 0.21 to 0.25 mg/L and seleno-cysteine from 0.25 to 0.35 mg/L after 6 weeks on the treatment, whereas there was no change in ewes fed Silage. Glutathione peroxidase increased, whereas haematocrit, haemoglobin and platelet count were decreased across time during the study, but there was no difference between the treatments. Conclusions Nano-Se provided by the Selage treatment was shown to be available to sheep and improve shelf life, with no adverse haematological effects. Implications There is potential to use silage inoculants to provide bioavailable Se to ruminants. Further research is required to determine the most appropriate dose for animal performance and product quality.
