“…2) in lambs of both groups a er birth was at a lower level until day 10 if compared with day 30 and 60, when it increased signifi cantly (P < 0.05) in both groups of lambs and when group B of lambs had an insignifi cantly higher RBC count during the entire experiment. Similar results like in our experimental lambs were reported by Faixová et al (2007). On the other hand Soliman et al (2012) and Ocal et al (2013) reported a higher RBC count in lambs compared to the presented results.…”

The objective of the study was to evaluate the infl uence of high iodine intake in ewes on haematological and biochemical parameters of the blood of ewes and their lambs. Twelve pregnant ewes of the Sumava sheep breed and their newborn lambs were included in the experiment. Control group (A) consisted of 6 ewes with 7 lambs and experimental group (B) comprised 6 ewes with 6 lambs. The feed ration was enriched with calcium iodate by addition of 3 and 5 mg/kg in group A and group B, respectively. The studied parameters in ewes and lambs were haematocrit value, red blood cell count and haemoglobin concentration in blood, concentration of urea and total proteins, and alkaline phosphatase activity in blood plasma. No diff erences were found out in haematocrit value, red blood cell count, concentration of haemoglobin and total proteins between groups of ewes A and B with their lambs. Urea concentration and alkaline phosphatase activity were higher in ewes of group B and their lambs during the entire experimental period. An increase in the values of urea and alkaline phosphatase in the group of ewes and lambs with higher iodine intake indicates a potential risk of high iodine intake associated with changes in the thyroid activity in ewes and their lambs.

“…Our previous experiment showed that the total erythrocyte count was significantly higher in Se-yeast supplemented lambs than in the control group, and the total white blood cell count was significantly higher in the control group than in the Se-yeast supplemented group (Faixová et al 2007). According to literature, selenium is essential in regulating haematopoiesis by differentiation of erythroid progenitors of C57/BL6 mice (Kaushal et al 2011).…”

Effect of dietary supplementation with selenium-enriched yeast or sodium selenite on ruminal enzyme activities and blood chemistry in sheep

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).

“…Since the main precursors of milk fat originate in the rumen, the increased milk fat content may have been influenced by rumen fermentation. The effect of Se supplementation in the form of yeast on the rumen fermentation was studied by Faixová et al (2007). They found significantly higher activity of alkaline phosphatase and glutamate dehydrogenase in ruminal fluid in Se-supplemented group.…”
