The Effect of Vitamin E and Selenium Injections on The Semen Quality of Bangkok Roosters (Gallus domesticus)

This study aims to determine the effect of vitamin E and selenium injections on the semen quality of male Bangkok chickens. The study used 18 male Bangkok chickens aged 1.5 years from April 10, 2023, to May 26, 2023, consisting of 3 treatments of 6 repeats using Complete Randomized Design, P0 (without injection of vitamin E and selenium), P1 (0.6 ml/head), P2 (0.9 ml/head). Chickens are kept in individual cages and given feed for corn, bran, and concentrates. Chickens are injected once every 2 weeks for 6 weeks. Data analysis used Analysis of Variance (ANOVA), descriptive analysis, and Kruskal Wallis Test followed by Duncans Multiple Ring Test and Mann-Whitney test. The result of observing the color of the injection treatment on Bangkok chickens was milky white, the smell was specific with medium thickness. pH, mass movement, and spermatozoa abnormalities were not significantly different in treatments P0, P1, and P2, the volume of semen obtained was significantly different in treatments P0, P1, and P2, the result of the mean sperm concentration in treatments P0 and P1 showed the significantly different result, however, P0 and P2 with P1 and P2 show no significant difference. It was concluded that the injection of vitamin E and selenium 0.6 ml/head had a better effect on volume and concentration than without injection and injection 0.9 ml/head.

Use of vitamin E and selenium injections as supportive treatment of retained placenta in dairy cattle

The placenta is considered retained when it cannot separate from the uterus beyond the normal time limit. Physiologically, a cow's placenta comes out 3-8 hours postpartum. This study aims to determine the diagnosis and treatment of retained placenta in dairy cows using vitamin E and selenium as supportive treatment. On physical examination the patient had a body temperature of 39.9°C, was weak, unable to stand, and had decreased appetite. General examination in this case showed the following clinical symptoms: the placenta was still hanging from the vulva and there was an unpleasant odor from the vulva area. The retained placenta was removed manually, followed by flushing the uterus with 0.2% povidone iodine (in water). Antibiotic (Colibact bolus) were introduced into the uterus and penicillin-streptomycin was injected intramuscularly along with vitamin E and selenium as supportive treatment. The results showed that the cow recovered and returned to estrus 14 days after therapy. It could be concluded that injections of vitamin E and selenium helped restore the estrous cycle in cows with retained placenta.

Selenium Injection in Dam Rabbits During Gestation Has Important Effects on Progeny Productive Performance.

Micromineral elements have a fundamental participation in the processes of organogenesis and fetal development. The objective of this study was to assess the effect of selenium (Se) injection in pregnant female rabbits, during organogenesis or rapid fetal growth, on the productive performance of their progeny. An experiment was carried out with 30 New Zealand female rabbits, with an average age of 6 months. At the end of mating (day 0), using a randomized complete design, the female rabbits were distributed into three experimental groups, which were assigned to the following treatments: Control, female rabbits were injected intramuscularly (IM) with 0.5 ml of saline on days 13 and 23 of gestation; Early administration, female rabbits that were injected IM with Se (0.10 mg/kg BW) on day 13 of gestation (organogenesis) and 0.5 ml of saline on day 23 of gestation; and Late administration, female rabbits that were injected IM with 0.5 ml of saline on day 13 of gestation and Se (0.10 mg/kg BW) on day 23 of gestation (rapid fetal growth). No differences were found on kindling performance of dams and pre-weaning growth of rabbit offspring. However, an injection of Se to pregnant rabbits affected the growth and development of their progeny, with the treatment leading to changes in the yield of some carcass traits (forelimb weight and forelimb muscle weight) and weights of some organs (liver, lungs, and spleen). The Se treatment (both early and late) also resulted in lower concentrations of glucose, triglycerides, and cholesterol when compared to the control group. These effects were different when Se injection was performed during organogenesis or rapid fetal development. The results from this study suggest that there are beneficial effects of gestational Se injection of rabbit dams on important productive traits of their progeny.

Prospective effect of vitamin E and selenium supplementation on colostrum quality in Beetal goats

This study was aimed to explore whether vitamin E (Vit-E) and selenium (Se) injections improve colostrum quality in goats. Twenty-four, healthy pregnant Beetal goats were randomly allocated into control (n = 12) and treated (n = 12) groups respectively. The injectable form of Vit-E 2.5 mg/kg BW and Se 2.2 mg/kg BW was administered fortnightly, while normal saline (0.9% NaCl) was used and served as a control group. Colostrum samples were collected immediately after parturition and subjected to biochemical analysis. Colostrum enzymatic and non-enzymatic antioxidants and total soluble proteins were investigated using a spectrophotometer. Antioxidants with enzymatic activities including superoxide dismutase (SOD) and peroxidases (POD) and ascorbic acid remained significantly higher in treated animals (P <0.05) in contrast to the control group. The Total antioxidant capacity (TAC) and total soluble proteins (TSP) levels were noted higher (P<0.05), however; the level of MDA existed significantly lesser in the treated group (P <0.05) in comparison with the control group. Overall, results showed that parental exposure to antioxidants (Vit-E and Se) improved antioxidant status in colostrum and upgrade its quality.

Peripartum Supplementation of Rumen Protected Choline and Fat and Se+Vit E in Gir Cows Economically Improves Endocrine Profile and Reproductive Performance

Background: The negative energy balance around calving and in early lactation is the major cause of increased incidence of postpartum metabolic disorders, reduced milk production and impaired reproductive performance. This study was aimed to evaluate the effect of rumen protected choline, fat supplementation and Vit-E and selenium injections on plasma endocrine profile, postpartum productivity, fertility and economics in transitional Gir cows. Methods: Forty advanced pregnant multiprous Gir cows of an organized farm were randomly distributed into five equal groups (T1 to T5; n=8 each) and were fed and managed individually from 30 days prepartum till 60 days postpartum. Cows in T1 (control) group were fed basal diet, while cows in treatment groups received basal diet + supplementation of rumen protected choline-RPC @ 45 g/d/cow (T2), rumen protected fat-RPF @ 80 g/d/cow from -30 to +15 days peripartum and then @ 10 g/kg milk yield (T3), RPC and RPF in combination @ as above (T4) and Inj. E-Care Se(R) 10 ml i/m (Vit-E 500 mg and Se 15 mg) on days -30, -15, 0, +15, +30 and +45 peripartum (T5) along with blood samples for estimation of plasma levels of insulin, IGF1, PGFM, estradiol (E2), progesterone (P4) and cortisol. The puerperal events and fertility parameters were recorded till 10 months postpartum. Result: The fortnightly plasma P4 concentration decreased, while E2, PGFM and cortisol increased gradually and significantly (P less than 0.01) from 30 days prepartum to day of calving and thereafter P4, E2 and cortisol remained basal or very low, while PGFM decreased till 45-60 days postpartum, overall and in all groups. The treatment effect was significant (P less than 0.01) only for E2 and PGFM, with higher values of E2 in T3 and T4 groups and of PGFM in T1 and T2 than in T5 group. The insulin and IGF1 concentrations fluctuated insignificantly during prepartum phase with significantly lowest values till 15 and 30 days postpartum and thereafter only IGF1 increased significantly by day 60 postpartum. The treatment effect was also significant at some intervals with overall highest values of both the metabolic hormones in T1 followed by T5 and T2 than T3 and T4 groups. The uterine involution was significantly earlier in all treatment groups than in control. The first heat postpartum (days) was significantly earlier in group T5 (33.6±3.4), delayed in group T1 (63.5±9.5) and intermediate in Group T2 to T4. The conception rates postpartum were 50.0, 75.0, 62.5, 75.0 and 87.5% in groups T1 to T5, respectively, with significantly reduced service period (days) in T5 (96.3±14.6), followed by T2 (137.3±11.2), than T1, T3 and T4 groups (187 to 214 days). The overall net returns over feed cost of milk yield and reduced service period in T2, T3, T4 and T5 groups over control T1 were Rs. +15898, +6150, +7165 and +24060, respectively. The findings reflected the beneficial and economic role of RPF alone or in combination with RPC and of Se + Vit E supplementation on peripartum endocrine profile and improved postpartum fertility in Gir cows.

Efficiency of Copper and Selenium during Estrus Synchronization on Estrus Behaviour, Estradiol and Progesterone Concentration in Salem Black Goats

Background: Copper and selenium were proven modulaters of reproductive function in ruminants under dietary supplementation. Their effects under pareneral administraton during estrus synchronization are not clearly defined. On this background the present was aimed to evaluate the effect of copper and selenium on estrus associated responses in goats. Methods: Thirty adult female Salem black goats were selected. On day ten of the estrus cycle, 250 µg of cloprostenol injection was given intramuscularly to all the animals and assigned to five groups. GI: control, GII: 4 µg of Buserelin, GIII: 20 mg cupric chloride, GIV: 10 mg sodium selenite and GV: copper plus selenium injections were administrated. Whole blood was collected for seven days for hormone assay. Estrus was detected using aproned bucks. Result: There was no significant (p greater than 0.05) difference in estrus response, onset and duration of estrus between groups. The progesterone concentration decreased significantly (p less than 0.05) from day 0 (before PGF2α) to day 1 (after PGF2α) in all groups. There was a significant (p less than 0.05) increase in estradiol and progesterone concentration in the GnRH group compared to other groups. Parenteral administration of copper and selenium did not significantly improve estrus behavior, estradiol and progesterone concentration in Salem black goats. GnRH was once again proved to be effective in the improvement of estrus associated responses in goats.

The effect of different types of in ovo selenium injection on the immunity, villi surface area, and growth performance of local chickens.

Background and Aim:The presence of free radicals may lower chicken’s performance. Thus, the antioxidant defense is needed and can be made through a nutritional approach such as selenium supplementation before hatches. This study aimed to investigate the type of selenium that, as an in ovo feeding (IOF) material, can provide the most enhancement of immunity, villi surface area, and early growth performance of local chickens.Materials and Methods:This study, with a completely randomized design, used 480 fertile Kampung Unggul Balitbangtan (KUB, a selected local breed) chicken eggs, with 120 eggs per treatment for four treatments. The four treatments of IOF material included the treatment with organic selenium yeast (SY), organic hydroxy-selenomethionine (HSM), inorganic sodium selenite (SS), and uninjected selenium (control). A solution containing 0.15 ppm of different selenium was injected into the egg amnion after 18 days of incubation. Once hatched, the chicks were placed in three individual cages for each treatment (capacity of eight birds per cage). The parameters observed were the villi surface area, antibody titer, the number of total and differentiated leucocytes, glutathione peroxidase (GSH-Px) activity levels, and growth and feed efficiency of the early growth performance.Results:All the in ovo selenium feeding, except SS, significantly affected the villi surface area, antibody titer, and lymphocyte and heterophil percentages; however, the feedings were still not optimal for enhancing antibody titers and total and differentiated leukocytes. All types of selenium were demonstrated to increase the activity of GSH-Px significantly compared to the control treatment (p<0.05). Furthermore, the daily gain and feed conversion ratio of the groups treated with SY and HSM was significantly improved compared to that of the control group.Conclusion:In ovo SY and HSM improve immunity significantly, villi surface areas and performance. Therefore, both types are the best nutrient ingredients of IOF for building immunity and producing good performance in chickens.

Effect of Vitamin E And Selenium Injection on Some Physiological Characteristics And Biochemical Parameters in Local Ram Lamb

The aim of present study was to investigate the response of vitamin E and selenium injection in local ram lambs on the hematological aspect, thyroid hormones, biochemical parameters, and growth rate. Twenty-four weaned (3-4 month old) ram lambs and averaged 20.827±0.5 kg in weight were used. The lambs were divided randomly into three groups (8 lambs each). 1st group was served as the control, the lambs were injected with 1.0 ml\head of physiological saline solution (0.9%), 2nd group (T1), lambs were injected intramuscularly with vitamin E 2.5 mg/kg of body weight and sodium selenite 25μg/kg of body weight and 3rd group (T2), the lambs were injected intramuscularly with vitamin E 5 mg/kg of body weight and sodium selenite 50μg/kg of body weight. The injection administered at weekly interval for 12 weeks. Results showed that T1 significantly increased packed cell volume (PCV %) and lymphocytes. The result of current study did not show a significant change between the test group in growth rate, ESR, thyroid hormones, biochemical parameter including (glucose, total protein, albumin, globulin, cholesterol, and triglyceride and aspartate aminotransferase).In conclusion, injection of vitamin E and selenium has positive effect on some physiological parameters in local ram lamb.

Vitamin E and Selenium Decreased Cortisol in Cattle

Abstract Twenty dairy cows with left abomasal displacement were used to investigate the effects of vitamin E and selenium treatment on blood cortisol in dairy cows stressed by omentopexy. The cows were randomly divided into two groups. Ten hours before surgery 6 g of DL-α-tocopheryl acetate (6 mg.kg−1) and 67 mg of natrium selenite (0.1 mg.kg−1) in a volume of 40 ml were administered subcutaneously to 10 cows; the control animals (n = 10) received an equivalent volume of injectable water (40 ml). The injection of vitamin E and selenium produced a rapid rise (P &lt; 0.05) in blood α-tocopherol and selenium concentrations. The serum vitamin E increased several times ten hours after vitamin E and Se injection and raised continuously to the highest average concentration of 21.6 mg.l−1 at hour 24 after the surgery. The highest selenium concentration was seen ten hours after selenium administration with holding the increased concentrations in comparison to initial ones during the whole study. Serum cortisol increased in both groups after surgery. The highest cortisol concentrations were reached at one hour after surgery in the experimental and control group (56.7 ± 28.8 and 65.3 ± 26.1 μg.l−1, respectively). A return to the levels similar to the initial ones was recognized 24 hours after the surgery. The ANOVA revealed a significant effect of vitamin E and selenium injection on serum cortisol (P &lt; 0.05). In conclusion, we have demonstrated that abdominal surgery resulted in typical stress changes with a weaker cortisol response to the abdominal surgery in animals treated with vitamin E and selenium.

Effects of inorganic selenium injection on the performance of beef cows and their subsequent calves

Sixty-seven pregnant Angus cows and their subsequent calves were used in a randomized design to evaluate the effect of inorganic Se injection from 80 d of gestation until weaning on cow reproductive parameters, BW and BCS evolution, milk yield and quality, calf growth and calf hematology parameters. The treatments were as follows: 1) Se+: cows were administered Se as sodium selenite at doses of 0.05 mg/Kg of BW at 80, 140, 200, 260 d of gestation and 30, 90, 150 and 240 d of lactation. Calves from Se + cows were Se as sodium selenite subcutaneously injected with a dose of 0.05 mg/Kg of BW at 70, 104, 144 d of age; 2) Control: cows and calves were administered sterile NaCl solution (9 g/l) at the same volume and intervals as Se + treatment. At the start of the experiment, forage Se concentration was 58.6 ppb ± 7.6 ppb, and cow whole blood Se concentration was similar (P > 0.10) between treatments (Se+, 29.3 ± 0.3 ppb; Control, 28.1 ± 0.5 ppb). After Se injection, cow whole blood Se concentration was increased (P < 0.01) in Se + cows in relation to control cows until the end of the experiment. Calf whole blood Se concentration was increased (P < 0.01) at birth and 30 d of age in calves from Se + cows compared to calves from Control cows. However, calf whole blood Se concentration was not different (P > 0.10) between treatments at d 70 after birth. After the first Se injection (70 d of age), calf whole blood Se concentration was increased (P < 0.01) at 104 and 144 d of age in calves from Se + cows compared to calves from Control cows. Cow BW and BCS did not differ (P > 0.10) between treatments throughout the experiment. Ovarian follicle diameter measured by ultrasound 47 d postpartum was greater (P = 0.03) in Se + cows compared to Control cows. Pregnancy rate to fixed time artificial insemination (FTAI), overall pregnancy rate (P > 0.10) and pregnancy loss (P = 0.19) did not differ between groups. Selenium injection did not affect (P > 0.10) milk yield and composition. Calf morphometric parameters, BW at birth and growth rate during lactation were not affected (P > 0.10) by treatments. No significant effect (P > 0.10) was observed between treatments on hematological results of blood samples from calves at weaning. Results of this study shown that inorganic Se injection was an efficient tool to improve Se-status in cow-calf operation under extensive management. Selenium injection increased follicle diameter in postpartum beef cow, however, did not affect the rest of the variables studied.

Synthesis of Anisotropic ZnSe Nanorods with Zinc Blende Crystal Structure.

Compared with the well-explored cadmium-based one-dimensional nanorods (NRs), it is still a challenge to produce heavy-metal-free II-VI semiconductor analogues with a controlled size, shape, and crystal structure. Herein, a synthetic strategy towards ZnSe NRs with a zinc blende crystal structure is presented, where use of the anisotropic nuclei produced via a high-temperature selenium injection favors anisotropic growth. Elongated ZnSe NRs were produced from anisotropic ZnSe nuclei, while spherical ZnSe nanocrystals were obtained starting from isotropic nuclei. The different free energy at (111) and (220) planes in anisotropic ZnSe nuclei induces the anisotropic growth of (111) plane for ZnSe NRs. Proper choice of the capping ligand (1-dodecanethiol) has an important implication for the formation of anisotropic ZnSe nuclei and also allows the control of the diameter of the final ZnSe NRs by limiting the growth of the (220) crystal plane of anisotropic ZnSe nuclei.

The effect of pre-breeding vitamin E and selenium injection on reproductive performance, antioxidant status, and progesterone concentration in estrus-synchronized Mehraban ewes.

The present study was conducted to assess the effects of pre-breeding vitamin E and selenium (ESe) injections on the reproductive performance, antioxidant status, and serum progesterone (P4) concentration in estrus-synchronized Mehraban ewes. During the breeding season, 38 ewes (3-4years) were divided into two groups (n = 18), and the synchronization of estrus was achieved by intravaginal insertion of 0.3g progesterone CIDR device for 13days followed by 350IU eCG at CIDR withdrawal. Ewes were kept under pasture conditions and exposed to Mehraban rams 48h following CIDR withdrawal. The experimental treatments were control and ESe injection. The ESe group was received three intramuscular (5mL) injections of Ese (0.5mg/mL of selenium as sodium selenite and 50IU vitamin E as DL-α- tocopheryl) once every 2weeks. Specifically, Ese was administered at 2weeks before CIDR insertion, at the times of CIDR insertion and CIDR withdrawal. Fertility, prolificacy, lambing rate, and birth weight were recorded after parturition. Blood samples were collected at CIDR insertion, CIDR withdrawal, 5, 10, and 15days after ram exposure. Fertility, prolificacy, lambing rate, and birth weight did not improve by Ese treatment, but viabilityof lambs was higher in ESe than control (P < 0.05). Serum total antioxidant capacity at day 5 and P4 at day 10 after ram exposure was higher in ESe than control (P < 0.05). In conclusion, sheep breeders can use ESe at CIDR insertion and withdrawal times to potentiate antioxidant status and progesterone profile of estrus-synchronized Mehraban ewes.

Clinical Preparations: Status Quo and Challenges in the Future

Dispensing clinical preparations requires the professional ability of pharmacists as specialists who understand the physicochemical properties of drugs. Clinical preparations contribute to the support of drug therapy and to commercialization by pharmaceutical companies. The Japanese Society of Hospital Pharmacists published the Guidelines on Hospital Preparations and Use in 2012. Those guidelines were designed to improve the safety and utility of hospital preparations, indicate the standard procedures for treatment in hospitals, and show how to ensure the quality of hospital preparations. The expiration dates for clinical preparations should be determined, although this is not done for most because of the numerous hospitals and differences in their approaches to quality control. Furthermore, the acquisition of informed consent for the use of clinical preparations is inadequate. After the guidelines were released, some problems have occurred, such as the underfilling of prescriptions for progesterone vaginal suppositories and overdoses of selenium injections. It therefore appears necessary to consider the development of a new procedural manual on clinical preparations. In this symposium, I discuss relief or safety measures for clinical preparations.
