Bu olgu ile bir kedide gözlenen Pulmoner Veno-Oklüzif Hastalık’ın patomorfolojik yönden incelenmesi amaçlanmıştır. 11 yaşlı erkek kedinin ekokardiyografisinde sağ atriumda kitle gözlendi. Tedavilerin ardından solunum güçlüğüne bağlı ölen kedinin nekropsisi yapıldı. Makroskobik olarak, mezenteriyal ve mediastinal lenf yumrularında ve kalpte kitleler ile karşılaşıldı. Akciğer muayenesinde ödem ve konjesyon ile konsolide alanlar görüldü. Histopatolojik olarak bağırsak, lenf yumruları ve kalpte neoplastik lenfoid hücreler gözlendi. Akciğerde şiddetli intimal fibrozise bağlı venlerin lümenlerinde daralma ve tıkanmalar dikkati çekti. Etkilenen çoğu damarların çevresinde kapillarizasyon gözlendi. Masson trikrom boyamasıyla intimal fibrozis tespit edilirken, tıkalı damarlar Verhoeff-van Gieson boyamasıyla gösterildi. Yapılan klinikopatolojik incelemeler sonrasında PVOD ve kardiyak metastazlı intestinal lenfoma tanıları konuldu. Bu olguda bir kedide Pulmoner Veno-Oklüzif Hastalık patomorfolojik yönden değerlendirilmiş ve PVOD ile lenfoma ile ilişkisi tartışılmıştır. Klinikopatolojik incelemeler sonucunda erkek bir kedide PVOH, intestinal lenfoma ve kardiyak metastazı tanımlanmıştır.Item Pericardial Abscess Associated with Mycoplasma arginini: A Rare Case from a Cat(Ankara Üniversitesi Veteriner Fakültesi, 2022) Akar, Aybars; Other; OtherA two and half-year-old, mixed breed, male cat was admitted to Burdur Mehmet Akif Ersoy University, Faculty of Veterinary Medicine, Animal Teaching Hospital with respiratory distress and coughing lasting for a month. During the initial examinations of ultrasound and radiography, a pericardial abscess was detected near the right side of the heart and was drained with pericardiocentesis. Percardial biopsy material was screened for the bacterial isolation and identification. Bacteriological methods based on colony morphology, sugar fermentation tests, and molecular confirmation using 16S rRNA-23S rRNA specific primers were performed. Result on conventional and molecular analysis, Mycoplasma arginini (M. arginini) were detected. The patient was treated with azithromycin and enrofloxacin. Full recovery was observed during follow-up examination after a month. The findings of this case increase awareness of pathogen M. arginini in cats and zoonotic importance has been emphasized for pet owners.Item Wound healing effect of Anzer origin propolis specimens on rats’ intestinal incision(Ankara Üniversitesi Veteriner Fakültesi, 2022) Sarıtaş, Zülfikar; Other; OtherThis study was investigated the wound healing effect of Anzer origin propolis specimens on rats’ experimental intestinal incisions. Thirty-four male Wistar albino rats have been divided into five groups, weighing 250-300 gr. Water solution of Anzer propolis (PW3 [n=6], PW7 [n=6]) or ethanolic solution of Anzer propolis (PE3 [n=6], PE7 [n=6]) were administered. Control groups (K3 [n=5], K7 [n=5]) received no treatment. The surgical procedure (day 0) consisted of a laparotomy under general anesthesia, during which the colon was incised and repaired with sutures. The Anzer propolis specimen diluted with physiologic saline was administered by gavage (100 mg/kg/day) for 3 and 7 days before and after surgery to PW3 and PW7 groups. Ethanol dissolved Anzer propolis was administered by gavage (100 mg/kg/day) for 3 and 7 days before and after surgery to PE3 and PE7. Experimental animals have been humanly euthanized on the 3rd and 7th days for biochemical and histopathological evaluations. Serum total oxidant status, total antioxidant status, interleukin-1, interleukin-6, tumor necrosis factor-alpha, myeloperoxidase, hydroxyproline and nitric oxide, levels were measured by ELISA. The incision line sampled to evaluate inflammatory cells, fibroblastic activity, neovascularization, and collagen level. The study indicates that the ethanolic Anzer propolis solution's oral administration has a beneficial effect on intestinal wound healing for seven days pre-and postoperatively (PE7).Item IPARD supports positively affect hematological parameters, milk production, and welfare indicators of dairy cows(Ankara Üniversitesi Veteriner Fakültesi, 2022) Arı, Hikmet; Other; OtherThe study investigated body condition score (BCS), hematological parameters, metabolic profile indicators, total oxidant-antioxidant status, and milk yield (MY) of cows in non-funded (NF) and funded (F+) dairy farms by the European Union funds (under the Instrument for Pre-accession Assistance for Rural Development-IPARD) to support rural development. Sixty multiparous Holstein cows (110 to 209 days of lactation) from 3 NF and 3 F+ dairy farms were used in the experiment. Hematological parameters were within physiological limits in both dairy farms. Total erythrocyte count and percent hematocrit were higher in the F+ group. Serum non-esterified fatty acids (NEFA) level and aspartate aminotransferase (AST) activity were higher in NF farms compared to the supported ones. The serum triglyceride, total cholesterol, glucose levels, and gamma-glutamyl transferase (GGT) activity were higher for the cows in F+ farms. The average daily MY and BCS of cows in NF and F+ dairy farms were 15.8 L and 2.83, and 24.4 L and 3.11, respectively (P<0.01). The total antioxidant status (TAS) of cows in NF farms was significantly lower than F+ farms, whereas total oxidant status (TOS) was significantly higher for cows in NF farms. In conclusion, the grant support is important in establishing a more capable, more efficient, and more suitable infrastructure for animal welfare, and positively affects the physiological health and efficiency of animals in these dairy farms.Item The negative effects of cold conditions on pregnancy rates in dairy cows(Ankara Üniversitesi Veteriner Fakültesi, 2022) Cengiz, Mehmet; Other; OtherThis study was conducted to determine the pregnancy rate in response to two sexual synchronization protocols in 70 healthy multiparous Fleckvieh dairy cows during the cold and warm seasons. After pairing by the actual parturition date [cold seasons (-38 to 0 ºC) (Nov - Feb) vs. warm seasons (0 to 32 ºC) (Mar-Oct)], cows were randomly subjected to either Co-Synch (CoS) or double PGF2α injection (dPG) on d 35 postpartum. Data were subjected to Chi-Square (2) analysis to determine the pregnancy rate at the first service. Overall pregnancy rates (%) at the first service were 57.1 and 40.0 for Groups CoS and dPG, respectively (2 = 2.03, P = 0.15) and 35.0 and 66.7% during cold and warm seasons, respectively (2 = 6.78, P = 0.009). The protocol effect on the pregnancy rate at the first service was insignificant during cold (2 = 1.17, P = 0.28) and warm (2 = 1.62, P = 0.20) season. In summary, the cold conditions negatively affected the pregnancy rate at the first service. The synchronization protocol methods did not differ to improve the pregnancy rate at the first service when cows were exposed to cold conditions.Item Ankara Üniversitesi Veteriner Fakültesi(Ankara Üniversitesi Veteriner Fakültesi, 2022) Toker, Eda Baldan; Other; OtherThis study reports the high prevalence and molecular characterization of BoHV-1 infection in imported cattle with respiratory system disease after international transport. A high mortality rate of 14.16% (51/360) was reported in a group of animals imported from Hungary to Turkey in 2019. A total of 17 samples were evaluated (3 lung tissue and 14 nasal swab samples) from 15 cattle aged 6 to 9 months not vaccinated against BoHV-1. Virus isolation, polymerase chain reaction (PCR) and restriction endonuclease analysis (REA) procedures were performed within the scope of this study. By virus isolation in MDBK cells, cytopathologic effects was detected in 8 samples (3 lung tissue and 5 nasal swabs samples). The same eight samples were also found positive by BoHV-1 PCR targeting gC (UL44) gene region. According to the sequencing result, the sample (ID: 10054) dropped into a cluster of BoHV-1.1. The REA was applied to the samples to confirm the results of phylogenetic analysis. All of the isolates were identified in the subgroup BoHV-1.1 by REA. These results showed a high mortality risk for imported animals and the possibility for BoHV-1 entering the receiving country via imported animals after transport. This event is a serious problem both for the control of BoHV-1 as well as for animal health and welfare.Item Chemical, rheological, and organoleptic analysis of cow and buffalo milk mozzarella cheese(Ankara Üniversitesi Veteriner Fakültesi, 2022) Bhat, Abdul Rauf; Other; OtherThis research was aimed to determine the impact of milk source on mozzarella cheese's chemical, rheological, and organoleptic characteristics. A total of 10 lots of cow and buffalo milk mozzarella cheese each were prepared. Prominent milk source influence on the chemical characteristics and calorific values of mozzarella cheese was determined. A decrease in moisture content and an increase in fat, protein, ash, and calorific values were noted in mozzarella cheese against their respective milk. Moisture content in cow milk mozzarella cheese (CMM) was considerably higher than buffalo milk mozzarella cheese (BMM). Average fat, ash content and calorific values appeared considerably high in BMM cheese compared to CMM cheese but protein content was recorded inverse and statistically non-significant (P>0.05). The average meltability was slightly higher in CMM cheese and the stretchiness of CMM cheese appeared significantly high from that of BMM cheese. BMM cheese was remarkably high in yield in contrast to that of CMM cheese. Appearance, flavor, and body/texture scores were slightly higher in CMM cheese as compared to BMM cheese. Regardless, the average benefit computed for BMM cheese was high in comparison to CMM cheese, the differences among them were statistically non-significant. The present study concludes that buffalo milk is better to produce mozzarella cheese with higher calorific values, better yield, and with more economic values, while cow milk is better to produce mozzarella cheese with the more proteinous, enhanced stretchiness, and better organoleptic quality.Item Some inherited disorders in pacing horses in Turkey(Ankara Üniversitesi Veteriner Fakültesi, 2022) Özbeyaz, Ceyhan; Veteriner; Veteriner FakültesiThis study was carried out to detect the presence of mutant alleles of polysaccharide storage myopathy (PSSM) and severe combined immunodeficiency (SCID) disorders in pacing horses raised in different regions of Turkey. Blood/hair samples from 264 (182 Indigenous, 31 Iranian, 24 Afghan, and 27 Bulgarian) pacing horses aged 4 and over were used. As a result of the study, a mutation-heterozygosis (GA) in the GYS1 gene related to PSSM disease was detected in one of the pacing horses (Bulgarian horse). No deletions were observed in the DNA-PKcs gene region in the pacing horses for SCID disease. This study has been carried out to identify the status of two inherited disorders in pacing horses in Turkey. It was determined that there are no mutant genes in indigenous pacing horses, in terms of PSSM and SCID disorders, which are the major hereditary disorders in horses.Item Comparison of growth and developmental stability traits of Japanese quails reared in conventional and enriched cages(Ankara Üniversitesi Veteriner Fakültesi, 2022) Narinç, Doğan; Other; OtherThis study was carried out to determine the effects of different rearing systems on some performance and welfare characteristics in Japanese quail. For this purpose, a total of 630 birds were housed in battery-type conventional cages, conventional floor cages and enriched floor cages. There were statistically significant differences between the experimental groups and the sexes in terms of the average body weight of the quails at 42 and 56 days of age (both P<0.01). Accordingly, it was determined that the average body weight of the quails raised in the conventional battery cages were higher than those raised both in the conventional and enriched floor cages. Gompertz growth curve model parameters of β0, β1, β2 were estimated as 262.05, 3.76, 0.050 for birds housed in battery-type conventional cages, 228.12, 3.57, 0.042 for birds housed in conventional floor cages, and 252.53, 3.86, 0.045 for birds housed in enriched floor cages, respectively. Among the bilateral traits, the highest mean value of relative asymmetry was found for wing length of birds reared in conventional battery type cages (P<0.01). As a result, it was determined that quails raised in conventional battery type cages are more advantageous for economic production. However, it may be recommended to use enrichment objects for an animal welfare oriented production system.Item Marker-assisted introgression of myostatin from Texel to Ramlıç sheep: Growth and real-time ultrasound carcass traits in F1 and BC1 lambs(Ankara Üniversitesi Veteriner Fakültesi, 2022) Çelikeloğlu, Koray; Other; OtherThe aim of the study was to evaluate live weights, body measurements, and real-time ultrasound carcass traits of F1 and BC1 genotypes in a marker assisted introgression (MAI) process. Effects of some factors on live weight and body measurements including ultrasonographic assessments in Musculus longissimus dorsi (MLD) were investigated at the F1 (n=51) and BC1 (n=99) cross lambs born in 2015 – 2017 period. Variance analysis showed that genotype had significant (P < 0.001) effect on pre- and post-weaning growth characteristics. The birth type had significant (P < 0.05) effect on pre- and post-weaning growth traits. Live weights at twelve months of age were higher in heavier born lambs. The growth performance of F1 lambs was between Texel and Ramlıç. Myostatin heterozygous BC1 lambs had been potentially heavier than the non-carriers and pure Texel. MLD depth and area were also statistically higher (P < 0.05) in BC1 lambs carrying myostatin than non - carriers. As a result, the beginning phase of introgression processes implemented was found to be successfulItem An investigation on the supplementation of rosemary volatile oil to the laying quail diets(Ankara Üniversitesi Veteriner Fakültesi, 2022) Deniz, Gülay; Other; OtherThe purpose of the current study was to detect the effects of different levels of rosemary volatile oil (VO) supplemented to laying quail diets on performance, egg quality parameters, and egg yolk oxidative stability. In this study, a total of 105 laying quails (Coturnix coturnix Pharaoh) at the age of 6 weeks were used and 3 main groups were formed, each containing 35 quails. Also, each main group was separated into 5 replicates containing an equal number of quails. Quails were fed a control diet without rosemary VO or diets which were containing at different levels (200 or 400 mg/kg) of rosemary VO supplemented to the control diet. At the end of the study, which was continued for a total of 56 days, no significant difference was found in the feed intake, feed efficiency and egg weights among the control and experimental groups. The supplementation of rosemary VO at the levels of 200 and 400 mg/kg to the diets caused an increase in quails' egg production (P<0.01). However, there was no effect on the exterior and interior egg quality parameters. A significant decrease in malondialdehyde (MDA) levels in egg yolk were observed with both levels of rosemary VO at storage (+4 0C) for 7 (P<0.001) and 28 (P<0.01) days. Considering these data, it was concluded that rosemary VO can be supplemented to laying quail diets as a natural antioxidant without negatively affecting performance and egg quality parameters.Item The monetary impact of zoonotic diseases on society: The Turkish Case(Ankara Üniversitesi Veteriner Fakültesi, 2022) Arı, Hakan Oğuz; Other; OtherIn this study, the burden of disease, costs, and animal losses caused by the seven most common zoonoses in humans and the two most common zoonoses in animals are calculated between 2016-2018 in Turkey. It aims to contribute to the literature by providing a holistic framework on the costs and burden of diseases of zoonoses in Turkey. The methodology of the study was based on the formula of ''Disease Burden of Zoonotic Diseases'' developed by the FAO. It was calculated under ''Burden of Early Mortality in Humans'', ''Burden of Morbidity in Humans'', "Financial Value of Lost Animals" and "Reduction in Production Capacity of Infected Animals". All cases which were registered in 2016, 2017 and, 2018 from the Ministry of Health (MoH) and the Ministry of Agriculture and Forestry (MoAF) concerning the relevant diseases were included in the study. It is found that the DALYs of all related zoonotic diseases increased and the costs for diagnosis, treatment, and prevention also rose between 2016-2018. The share of total social cost in the GDP of Turkey was estimated to be 0.0090% in 2016, 0.0097% in 2017, and 0.0113% in 2018. It is argued that the seven zoonoses in the scope of this study have an increasing burden graph on Turkish society between 2016-2018. Moving from the fact that most infectious diseases that threaten human and community health are of zoonotic origin and difficulties in predicting when, where or how a zoonotic disease will occur, all sectors should continue to carefully monitor events related to zoonoses and carry out joint studies.Item Prevalence and rapid identification of Salmonella Infantis in broiler production in Turkey(Ankara Üniversitesi Veteriner Fakültesi, 2022) Sareyyüpoğlu, Barış; Veteriner; Veteriner FakültesiIn the present study, the prevalence of Salmonella enterica subsp. enterica serovar Infantis (S. Infantis) and other serovars were investigated in samples collected from commercial broiler chicken flocks in Turkey according to the ISO 6579:2002/Amd 1:2007, Annex D, standard method. Furthermore, previously developed S. Infantis-specific polymerase chain reaction (PCR)-based methods with primers targeting fljB, fliC, IMP1-IMP2-IMP3 and sinI were conducted in different media (BPW, MRSV, MKTTN, XLD, and XLT4 agars) and during four incubation stages (6, 12, 18, and 24 h) of the ISO 6579 procedure to develop rapid and reliable diagnosis method. One-hundred thirty-three (15.6%) Salmonella strains were isolated from a total of 848 samples (240 cecal swabs, 200 cloacal swabs, 190 intestinal contents, 59 feed, 39 dust, and 120 litter). The serovar distribution of isolated strains was as follows: S. Infantis, 88.70%; S. Agona, 2.3%; S. Kentucky 1.50, S. Hadar 1.50, and S. Tennessee 1.50; S. Mbandaka 0.75 %, S. Montevideo 0.75 %, S. Enteritidis 0.75 %, S. Adelaide 0.75 %, S. Liverpool 0.75 %, and S. Derby 0.75 %. Primers targeting fljB, fliC, and IMP1-IMP2-IMP3 were not able to detect all S. Infantis isolates, therefore, a novel PCR technique was developed and validated in the study. It was concluded that it is a fast, reproducible and low-cost alternative to the gold standard method by detecting the S. Infantis isolates on the 3rd day at the earliest by PCR (sinI PCR). using primers specific to S. Infantis species.
