Item Ankara Üniversitesi Veteriner Fakültesi(Ankara Üniversitesi Veteriner Fakültesi, 2022) Daşkın, Ali; Veteriner; Veteriner FakültesiIn this case, semen that handled by urethral catheterization was deposited into the deepest point of the vagina of an anesthetized queen. Intravaginal artificial insemination was applied on the 2nd day of onset of the oestrus and only single insemination was performed. Insemination time was determined by behavioural and cytological evaluations. Two healthy kittens were obtained 62 days after insemination. The case has important reports in terms of being the first artificial insemination performance in cats in Turkey, resulted in parturition.Item Comparison anti-oxidant and neuroprotective effects of extra-virgin olive oil, donepezil and rosmarinic acid on aluminum chloride-induced Alzheimer’s in rat models(Ankara Üniversitesi Veteriner Fakültesi, 2022) Altıntaş, Levent; Veteriner; Veteriner FakültesiIn this study, it was aimed to investigate the effects of EVOO, rosmarinic acid and donepezil in Alzheimer's model to be created with AlCl3 in rats. For this reason, administration of 100 mg/kg aluminum chloride (AlC3) for 15 days to Sprague Dawley adult male rats; donepezil, Extra-virgin olive oil (EVOO) and rosmarinic acid were administered to three different groups for 21 days by applying treatment protocols. With this study, we were able to demonstrate that cognitive impairment has been occurred after 15 days of AlCl3 administration by oral gavage and treatment protocols prevented the occurrence of AD pathology histopathologically. We also showed that oxidative damage findings which are positively Congo-red stained cell cytoplasm and impaired cell integrity have been observed in serum and hippocampus. Besides, treatment groups showed better cognitive and motor performance, and there was no damage to the cells in control and treatment groups. In the rotarod motor performance test, a significant increase was observed in the donepezil group compared to the AlCl3 group at speeds of 26 and 30 rpm. In MVM, on the 5th day of the experiment, a significant increase was observed in the donepezil group compared to the AlCl3 group, as they were spending more time in the hidden platform area. These results show that 15 days of aluminum exposure is effective in creating a moderate Alzheimer’s pathology, but further chronic research is necessary to explain the efficiencies of rosmarinic acid and EVOO in treatment.Item Detection of Clostridium perfringens and determination of enterotoxin genes (cpa and cpe) in traditional turkish chicken doner kebab(Ankara Üniversitesi Veteriner Fakültesi, 2022) Kevenk, Tahsin Onur; Veteriner; Veteriner FakültesiThe demand for the fast-food industry in the world is increasing day by day. In this sense, chicken doner kebab becomes frequently preferred food source in daily life. At the same time, chicken doner kebab is both a good animal origin protein source and a cheaper option. Therefore, it is prepared and consumed in high amounts in Turkey. In this study, it was aimed to determine the presence of Clostridium perfringens and its toxin genes in traditional Turkish chicken doner kebabs purchased from restaurants and modified atmosphere packaged (MAP) samples collected from markets. For this purpose, 100 ready-to-cook and 100 ready-to-eat, totally 200 doner samples have been used as material. As a result, the prevalence of C. perfringens has been found 29%, 6% in ready-to-cook and ready-to-eat samples, respectively. The cpa gene was detected in all isolates. However, both cpa and cpe gene was found only in 4% of isolates.Item Determination of factors affecting competitiveness through technical and economic analyses of dairy cattle enterprises in Balıkesir province(Ankara Üniversitesi Veteriner Fakültesi, 2022) Cevger, Yavuz; Veteriner; Veteriner FakültesiIn this study, technical and economic analysis of dairy cattle enterprises in Balıkesir province were carried out. The factors which affect the competitiveness of enterprises and are important in terms of the continuity of production were determined. The stratified sampling method was used to determine the sample, and the study material was two-year (2017–2018) data obtained from 147 enterprises. In addition to the economic analysis of the data obtained, factors affecting unit profit in enterprises were estimated using the multiple linear regression model. The cost elements in total enterprises in Balıkesir province in 2017–2018 include feed expenses (47.90%-47.29%), livestock depreciation (16.64%-16.13%), labor expenses (13.84%-14.30%), veterinary health expenses (4.03%-4.50%), fuel transportation expenses (3.43%-4.15%), building equipment depreciation (3.37%-3.64%), and other expense items. A distinct difference was observed between scales in terms of profit and loss states of the enterprises in the study, with an increase in the profitability level from small toward large scale enterprise. The small-scale enterprises, in particular, are at a loss. The most important determinant of competitiveness in the study is the region’s development level, where the enterprises are established in the borders of Balıkesir province. Additionally, among the technical parameters, the calving interval and the reduction of the disease rate have a positive effect on the competitiveness of the enterprises. Therefore, improving the financial structure of the enterprises and boosting the rate of technology utilization while simultaneously increasing enterprise scales will contribute positively to competitiveness.Item Determination of goat milk cost and assessment of factors affecting the profitability of Saanen goat enterprises in Çanakkale province, Turkey(Ankara Üniversitesi Veteriner Fakültesi, 2022) Gökdai, Arzu; Veteriner; Veteriner FakültesiThe aim of this study is to determine the cost of goat milk in Saanen goat enterprises in Çanakkale province and to examine the factors affecting profitability in enterprises. The material of the study consists of 92 Saanen goat enterprises. The enterprises have been grouped according to their animal density; as 25-75 heads (small-scale), 76-150 heads (medium-scale) and 151 heads and above (large-scale). The findings of the enterprises for 2017 were determined by descriptive statistics, and multiple regression analysis was used to determine the factors affecting the total profitability of the enterprises. Since feed costs represented 46.22% of total production cost, it was followed by labour costs (27.19%), fuel costs (5.44%) and veterinarian-health service costs (5.19%). The cost of 1 L milk and absolute profit in enterprises was determined as 0.42/0.01 / k g i n s m a l l − s c a l e , 0.41 / 0.02 /kg in medium-scale and 0.38/0.05 $/kg in large-scale enterprises, respectively. It was observed that the share of inputs in enterprises generally decreases as the scale of the enterprise increases and large-scale enterprises were found to be more successful in solving technical, health and economic problems.Item Effects of calving year, season, and age on some lactation traits of Anatolian buffaloes reared at farmer conditions in Turkey(Ankara Üniversitesi Veteriner Fakültesi, 2022) Küçükersan, Seher; Veteriner; Veteriner FakültesiThe aim of this study was to investigate the effects of some environmental factors like calving year, season, buffalo cow age and village on some milk yield traits of Anatolian buffaloes, such as daily milk yield for lactation length (MYLL), total lactation milk yield (TLMY), lactation length (LL), and daily milk yield for calving interval (MYCI). 1838 milk yield records obtained from 851 Anatolian buffaloes reared under different environmental conditions from 2015 through 2019 within the scope of the Bartın Anatolian Buffalo Breeding Project were assessed. The least square means and standard errors for MYLL, TLMY, LL, and MYCI were 4.07 0.02 kg, 1078.6 7.54 kg, 263.83 1.16 days, and 2.75 0.03 kg, respectively. As a result of the study, the effects of village, calving year and age (P<0.001) and calving season (P<0.05) on MYLL; village, calving year and age (P<0.001) on TLMY; village, calving year and age (P<0.001) and calving season (P<0.05) on MYCI; calving age, village (P<0.001) and calving year (P<0.05) on LL were found statistically significant. Moreover, high positive phenotypic correlations between TLMY and MYLL (r = 0.78, P<0.001) and LL and TLMY (r = 0.67, P<0.001) were estimated. The results revealed that milk production traits might be improved by considering calving season and age in breeding studies and stud-selection programs in Anatolian buffaloes. Besides, it will remarkably contribute to the number of limited studies that have focused on this breed.Item Investigation of the effects of fetal rat kidney-derived mesenchymal stem cells implementation on doxorubicin-induced nephropathy in male Sprague–Dawley rats(Ankara Üniversitesi Veteriner Fakültesi, 2022) Özen, Doğukan; Veteriner; Veteriner FakültesiThe potential protective effects of mesenchymal stem cells (MSCs) on some kidney diseases have been reported. However, the effect of the fetal kidney–derived (FKD)MSCs on doxorubicin-induced nephropathy has not been studied yet. This study aimed to treat rats with doxorubicin-induced kidney injuries by transplantation of –FKD-MSCs. Twenty-four Sprague-Dawley rats were divided into three groups as control, doxorubicin nephropathy (Sham), and doxorubicin + MSC treated group. Serum biochemistry analysis was performed at the beginning and the end of the study. Functional changes in kidneys were evaluated by scintigraphy. In the doxorubicin nephropathy group, histopathological findings such as mesangial cell proliferation, tubular cast, and glomerular hypertrophy were observed, whereas in the MSC group these findings were significantly reduced. CD133 and CD24 positive immunoreactions were the most severe and frequently observed in the MSC group. While positive staining was detected in the tubular epithelium, there was no immunostaining observed in the glomerulus. The results showed that both functional and histological improvements were achieved in the MSC group compared to the Sham group. In conclusion, transplantation of fetal kidney - derived MSCs into patients with renal damage is thought to contribute to the healing of the renal tissueItem What has been done in the fight against Varroa destructor: from the past to the present(Ankara Üniversitesi Veteriner Fakültesi, 2022) Sevin, Sedat; Veteriner; Veteriner FakültesiBees are the major pollinators in natural ecosystems and in the agricultural production of several crops used for human consumption. However, they are exposed to multiple stressors that are causing a serious decline in their population. We highlight a major one among them, the Varroa destructor mite (Varroa) that causes severe impacts on the health of honey bee colonies, transmitting a variety of viruses that can affect the survival ability of individual bees and entire colonies. Diagnosis and mite control methods have been intensively studied in recent decades, with many studies in different areas of knowledge having been conducted. This overview summarizes these studies with a focus on colony defense systems, biological characteristics of the parasite Varroa, diagnostic methods used to establish the infestation level of colonies, and currently used control methods.
