“…In the present study, Se and vit E injection had significant effect on the eosinophil number with higher value in supplemented lambs. This finding was not supported by the results of Aksakal et al [21] and Mohri et al [20] who reported no Fig. 1 Effect of treatment on the amounts of parameters with significant age and group interaction in lambs difference for eosinophil numbers between supplemented lambs and calves in comparison with control ones.…”

“…Higher values of hemoglobin and PCV were reported in lambs injected by vit E and Se in comparing to control lambs [19]. In the study of Mohri et al [20], the higher levels of PCV and hemoglobin was reported at the third and fourth weeks of life in Se (as sodium selenite) and vit-E-injected calves. On the other hand, Aksakal et al [21] reported no changes for PCV, and RBC levels in Se (as sodium selenite) and/or vit-E-supplemented lambs in comparing with control ones.…”

“…No significant changes of white blood cells profile were reported in sheep during Se supplementation as sodium selenite and organically bound Se in algae [24]. In contrast, other studies indicated higher leukocyte counts in Se-supplemented lambs [21] and calves [20,22]. Similarly in rat, WBC counts were significantly higher in vit-E-and Se-injected groups than in the control ones [23].…”

Most regions in Iran are generally selenium (Se) deficient and all mineral premixes which used in farm animals contain Se in the form of sodium selenite. The objective of this study was to evaluate the effects of injected Se and vitamin E (vit E) on hematology, serum proteins, and performance of lambs during the period which the animals are at risk of Se and/or vit E deficiency. The study also aims to determine the relationship between selenium injection and the levels of other trace elements in blood serum of lambs. A total of 16 lambs of Baloochi breed (age, 70 ± 7 days and weight, 15.2 ± 1.4) were enrolled in the study. The animals were divided into two groups. In the test group, vit E and Se injected at a dose of 0.2 ml/kg BW (Vetoquinol, Selepherol®, Lure Cedex, France, α-tocopherol acetate 3.82 g/100 ml plus sodium selenite 0.023 g/100 ml) at the enrollment. Control lambs were received equal amounts of normal saline as placebo. Blood was sampled from the jugular vein at the beginning of the study (enrollment, before injection of vit E and selenium and saline) and at days 7, 14, 21, and 28 of experiment. The amounts of total serum protein, albumin, glucose, iron, copper, zinc, creatine kinase (CK), and aspartate aminotransferase (AST) and Se were measured. The concentration of globulin was calculated as the difference between total serum protein and albumin. For evaluation of growth and health, body weight of all the lambs was measured at day 0 of the experiment and the sampling times and days of treatment for each lamb were recorded. Treatment with Se and vit E decreased the activities of CK and AST compared to the controls (p < 0.05). Age (sampling time) had significant effects on the values of Se, iron, zinc, AST, hemoglobin, total protein, glucose, weight, height, and length (p < 0.05). Significant interactions between sampling time and group were seen for CK, AST, iron, glucose, weight, and length. No significant differences were seen for total weight gain (control, 3.48 ± 0.75 kg; test, 3.85 ± 0.9 kg), and average daily gain (control, 0.12 ± 0.03 kg; test, 0.14 ± 0.03 kg) between trial groups.

“…Treatments affect WBC and neutrophil cell counts (Table 6). Similarly, Mohri et al [28] reported that Se and VE supplementation affected the WBC counts in calves. The WBC counts were significantly higher in Se-and VE-injected groups of rats than in the controls [7].…”

Forty heifers at the late stage of gestation were randomly assigned into five groups. Heifers were balanced for age, weight, and time of calving in each group. Four and 2 weeks before expected time of calving, the heifers were injected with 0 ml (C), 10 ml (T1), 20 ml (T2), 30 ml (T3), and 40 ml (T4) Se and VE supplements, respectively. Each milliliter of the supplement contained of 0.5 mg Se as sodium selenite and 50 IU of dl-alpha-tocopheryl acetate. Blood samples were collected from the heifers 4 weeks before expected calving and at calving day and from the calves at birth and 7 days of age. The serum Se and immunoglobulin G (IgG) concentrations, white blood cell and differential leukocyte counts were measured. The Se concentrations in the sera of the heifers before the injections of Se and VE supplements were the same among the groups (P > 0.05), but after calving were significantly increased in the treated heifers (P < 0.05). Similarly, the serum Se levels of calves of the treated heifers were higher (P < 0.05). The Se concentrations in the colostrums of the heifers were affected by treatments (P < 0.05). Colostrum and daily milk productions at 8-week lactation were increased in treated heifers compared with the controls (P < 0.05). Likewise, the milk somatic cell counts decreased in the treated heifers compared with the controls. The changes of the mean serum IgG levels did not differ among calves (P > 0.05). The white blood cell counts were higher in calves of heifers in groups T3 and T4 compared with the control group at 7 days of age (P < 0.05).

“…As demonstrated in various studies, oxidative stress plays an important role in the development and course of respiratory syndrome in cattle, and reducing it can significantly decrease the incidence of respiratory symptoms in cattle (5,18). Studies on humans infected with the syncytial virus (RSV) have also confirmed the therapeutic and prophylactic effect of antioxidant formulations in the prevention of respiratory syndrome (4).…”

SummaryBovine respiratory disease (BRD) in cattle, due to the participation of numerous viral and bacterial etiological agents, predisposition factors, and environmental stresses, is a serious health and economic problem in herds of beef cattle. Given the broad scope of the problem of respiratory syndrome and the limited immunoprophylaxis, the aim of this study was to estimate the additive effects of flunixin with florfenicol followed with vitamin E or/and C in reducing the development of oxidative stress and inflammation in the first weeks in the feedlot.The study was conducted on young Simmental cattle (n = 50) weighing approx. 160 kg. The animals were divided into 5 groups (n = 10 in each group). Group I was the control. The cattle received florfenicol and flunixin in combination with vitamins E or C (Group II and III), florfenicol and flunixin followed with vitamin E and C (Group IV), or florfenicol and flunixin without vitamins (group V). Blood for sera was collected on the day the drugs were administered and on days 3, 7, 14, 21 and 28 of the experiment. The level of oxidative stress was analysed on the basis of the concentration of nitrogen ions (NO) in the sera and of lipid peroxidation end products reacting with thiobarbituric acid (TBARS). Concentrations of haptoglobin (Hp) and serum amyloid A (SAA) in the sera were determined using EIA enzyme immunoassays.The treatment used in the study, involving the application of florfenicol and flunixin with vitamin E or C, substantially reduced the level of oxidative stress, expressed as a reduced concentration of TBARS and NO ions, particularly in groups II and III. It was also confirmed that the treatment inhibited the concentration of acute phase proteins (Hp and SAA).
