Öğe Effects of Oregano Essential Oil on Reduction of Weaning Age and Increasing Economic Efficiency in Holstein Friesian Calves(Zoological Soc Pakistan, 2020) Tapki, Ibrahim; Ozalpaydin, Huseyin Bahadir; Nuran, Tapki; Aslan, Mehmet; Selvi, Muhammet HanifiThis study examined the potential use of oregano essentail oil as a milk additive for purposes of reducing weaning age; increasing economic efficiency; promoting calf growth as well as for improving blood parameters and general health status of Holstein Friesian calves. Twenty-eight Holstein Friesian calves were allocated into three groups: (a) Control calves were fed with whole milk (n=10), (b) OreganoLow (n=9), and (c) OreganoHigh (n=9) calves were fed with whole milk, plus 100 and 150 mg/l oregano essential oil per kg milk respectively. The amount of the milk offered on daily basis was calculated as 10% of each calf live weight and was given in two meal times. All calves were kept in individual pens during experimental period. Calves got weaned following the consumption of daily 900 g of concentrate feed over three consecutive days. Results demonstrated that OreganoLow calves marked improved growth performance, earlier weaning age and lower farm costs (P < 0.05) compared to Control and OreganoHigh calves. To conclude, dietary oregano essential oil seems to be a potential liquid feed additive that improves feed efficiency, health status, growth performance, and that reduces diarrhea incidents, hastens weaning age and minimizes dairy farm costs when used at the level of 100 mg/l.Öğe Oxidative stress markers in IVF patients and their association with pregnancy results(Turkiye Klinikleri, 2014) Güler Okyay, Ayşe; Aslan, Mehmet; Taşkin, Abdullah; Selek, Sahbettin; Ceng Altin, Günseliiz; Kahraman, SemraObjective: Oxidative stress has been well recognized as a component in the pathogenesis of many diseases, including female infertility. In this study, we aimed to investigate serum paraoxonase (PON1), arylesterase and myeloperoxidase (MPO) activities, and lipid hydroperoxide (LOOH) levels as oxidative stress markers along with their relationship with the pregnancy rate in women undergoing in vitro fertilization (IVF) treatment. Material and Methods: Serum samples of 179 subjects were collected immediately before starting ovarian stimulation and on ovum pick-up (OPU) day during IVF treatment. Stimulation protocol and starting doses were determined individually. When the leading follicle reached at least 17 mm in size, recombinant human chorionic gonadotropin (Ovitrelle, 250 mcg, Serono) was administered for ovulation induction. Serum basal/salt-stimulated paraoxonase, arylesterase activities, myeloperoxidase activity, and lipid hydroperoxide levels were compared between two samples. Subjects were also divided into two groups according to the presence of pregnancy, and the groups were compared in terms of oxidative stress markers studied. Results: Serum MPO activity and LOOH levels were significantly higher on ovum pick up day (p<0.05, p<0.001, respectively), while basal/salt-stimulated paraoxonase and arylesterase activities were significantly lower (p=0.012, p=0.041, respectively) than those before ovarian stimulation. Serum LOOH levels on OPU day were significantly higher in non-pregnant group than pregnant one (p<0.001). Although basal/salt-stimulated paraoxonase, arylesterase and myeloperoxidase activities were higher in the non-pregnant group compared to the pregnant group, it was not statistically significant (p>0.05). Conclusion: Ovarian stimulation during IVF treatment resulted in increased oxidative stress and decreased PON1 activity. However, changes in the studied parameters were not found to be significantly associated with the pregnancy results. Further studies are required to clarify our results. © 2014 by Türkiye Klinikleri.Öğe THE RESEARCHES ON SOYBEAN (Glycine max Merr.) VARIETY BREEDING FOR RESISTANCE TO WHITEFLY IN TURKEY(Soc Field Crop Sci, 2010) Gulluoglu, Leyla; Kurt, Cemal; Arioglu, Halis; Zaimoglu, Bihter; Aslan, MehmetThis study was conducted in the Cukurova University, Faculty of Agriculture, Department of Field Crops in between 1993 and 2003 in Turkey. The objective of this research was to breed high yielding whitefly (Bemesia tabaci Genn.) resistant soybean cultivar. Soybean cultivar S.4240 and Williams was crossed in 1993. Individual plant selection was made according to single-seed descent selection method in the segregating materials. The F-2 seeds were planted and one random F-3 seed (pod) was taken from each F-2 plant. This process was repeated until the plants were considered sufficiently true-breeding F-5 generation. All the F-5 seeds were planted as a second crop and 200 individual plants were selected among the F-5 plants according to breeding objectives at the harvesting time in 1998. The selected seeds plants were planted in separate rows in 1999 and 2000. Nine rows (lines) were selected according to breeding objectives at the end of 2000 growing season. The replicated yield test was repeated in 2001 (with 9 soybean lines), 2002 (with 7 soybean lines) and 2003 (with 7 soybean lines) seasons with selected soybean lines under double cropping conditions. At the end of 2003 growing season, three breeding lines (SW-3, SW-7 and SW-11) were determined as cultivar candidates.Öğe The researches on soybean (Glycine max merr.) variety breeding for resistance to whitefly in Turkey(2010) Güllüoğlu, Leyla; Kurt, Cemal; Arıoğlu, Halil Halis; Zaimoğlu, Bihter; Aslan, MehmetThis study was conducted in the Cukurova University, Faculty of Agriculture, Department of Field Crops in between 1993 and 2003 in Turkey.
