This study aimed to estimate the total financial (direct and indirect) and avoidable losses related to lameness in Turkish dairy herds. Official and previous published data were used for determining the mean (12.9%) and target prevalence (6.6%) values. Direct financial losses due to lameness were calculated as treatment costs, involuntary culling, and milk yield losses. Indirect losses consisted of extended calving intervals and extra insemination losses. As a result, an average financial losses of lameness per case on dairy farms was $153.8 ($116.8 for mild and $264.7 for severe forms). Avoidable losses were calculated ($75.1), equalling 187 Lt. of cow milk in Türkiye conditions. The share of direct and indirect financial losses was 49.6% and 50.4%, respectively. Total annual losses related to lameness in Türkiye are calculated as $130.5 million (326 million Lt. milk eq.); however, $63.7 million (=159 million Lt. milk eq.) of the losses could be avoided by farmers. Milk equivalent of avoidable losses equates to 0.77% of the total milk production of Türkiye annually. In conclusion, lameness causes significant financial losses in Turkish dairy herds. However, almost half of these losses (48.8%) may be avoidable with a better management practices, thus increasing the productivity and profitability of dairy farmers.

Superficial pyoderma is a common complication of a range of feline and canine skin diseases. The objective of the present study is to retrospectively evaluate bacterial and fungal skin culture samples in superficial pyoderma cases of cats and dogs and to reveal in detail the pathogens and their susceptibility and/or resistance to antimicrobials, as well as demographic data and clinical symptoms of the patients. Medical records of 28 cats and 35 dogs meeting the criteria for inclusion were reviewed. Staphylococcus spp. and Trichophyton species were found to be the most common cultured microorganisms in both cats and dogs. Antimicrobial resistance was determined both in cat and dog samples. As a result, it has been demonstrated that skin culture is particularly important for the management of diagnosis and treatment processes and the regulation of treatment protocols in pyoderma in terms of preventing the increasing antibiotic resistance in recent years and thus protecting both human and animal health.

With the official announcement of the new type of coronavirus-induced COVID-19 outbreak as a global pandemic, a special situation that no one has ever encountered has started. Developments that are expected to happen in next decade in many fields have been completed in the last 3 years. One of these fields was undoubtedly education. Hybrid learning is a trending educational approach that combines face-to-face and online learning. The aim of this article is to give ideas and make suggestions about how plastinates, which have been used efficiently in anatomy practices and professional training, can be used in hybrid learning of veterinary anatomy. Plastinated specimens come to the forefront for hybrid education with various advantageous features. They are not only non-toxic, dry, odorless materials, but plastinates also can simulate the natural anatomic appearance in a detailed manner. With the help of new-generation acrylic paints and dyes which can penetrate into tissues, plastinates offer a unique natural look rather impressive than any other techniques. Due to the features mentioned above, plastinates are also convenient materials for handling, transportation or storage. These specified properties were discussed in terms of the compatibility to hybrid learning procedures in this article.

The objective of this study is to report clinical, MRI, surgical and histological findings of spinal meningothelial meningioma in a dog. Study material was a 9 years old, spayed dog with history of progressive non ambulatory tetra paresis. The dog had intact cranial and spinal reflexes, and deep pain perception. Magnetic resonance images revealed a mass located at left side C2-C3 level, hyperintense in T1W, isointense on T2W, well contrast enhancing on postcontrast T1. The mass was microsurgically resected sub gross totally. The dog’s neurological status was improved at one week and survived for 15 months without signs of metastasis. Histological and histochemical workup revealed grade I, meningothelial meningioma. Surgical intervention for spinal meningioma can be suggested as a sole treatment in dogs.

Artificial intelligence is a developing concept in the field of veterinary medicine, as in other health fields. The study was carried out to determine the knowledge levels of the students of Ankara University Faculty of Veterinary Medicine, which is the most established veterinary faculty in Türkiye, on the concept of artificial intelligence and its use in veterinary practices. For this purpose, an online questionnaire was applied to a total of 529 students who wanted to participate in the study, covering all grades of the faculty. The questionnaire consists of two parts. In the first part, there are 10 questions including demographics, level of computer use, knowledge about the concept of artificial intelligence, etc. The second part consists of 26 5-point Likert-type questions to determine students' thoughts on artificial intelligence applications. Data were analyzed using statistical tests. Consequently, the students participating in the study are partially knowledgeable about artificial intelligence (52.9%). They know the importance of following the developments in artificial intelligence for the profession (45.2%). They think that artificial intelligence applications will improve their professional skills (53.5%). They have the opinion that a robot cannot replace a veterinary surgeon (36.7%) and artificial intelligence cannot cause unemployment in veterinary medicine in the future (35.3%). In addition, they believe that artificial intelligence can cause ethical problems (39.3%) and that applications made with this technology should be developed in an ethical sense (42.4%). As a result, while the students think that artificial intelligence will have positive effects in the field of veterinary medicine, they also think that artificial intelligence can bring negative ethical implications. It can be concluded that including elective courses on artificial intelligence applications in veterinary faculties and conducting further research on the subject would be beneficial.

The objectives of this study were to report mean serum AMH concentrations in adult queens, to determine relationship between AMH concentrationss with estradiol level, to investigate the relationship between serum AMH with follicular phase and interestrus period and to discuss the usability of AMH as a biomarker to diagnosis of ovarian remnant syndrome. In the study, 64 adult and healthy female queen, who were brought to clinics for ovariohysterectomy were used. After anamnesis, vaginal cytology, macroscopic examination of the uterus and ovaries and estradiol measurement, queens were divided into two groups: follicular phase (n: 45) and interestrus (n: 19). Estradiol and AMH levels in serum samples were determined by ELISA. In the evaluation of serum AMH concentrations, a statistical difference was determined between the follicular phase and interestrus (p˂0.05). A negative correlation was found between age and estradiol in both follicular phase (r = -0.171) and interestrus (r = -0.385) groups. A positive correlation was found between age and AMH in the interestrus (p˂0.01, r = 0.696). Serum AMH levels in the interestrus were found to be significantly higher than follicular phase (p˂0.05). It was thought that this increase in serum AMH levels during the interestrus period, which is the stage where oocytes were selected for ovulation, may be an indicator of the role of AMH in oocyte selection in queens, as in many other mammalian species.

Structural patterns of pyloric tonsil in turkeys (Meleagris gallopavo) were investigated in this study. Turkeys, less resistant to disease than chickens, are a crucial source of protein with low cholesterol levels and a high protein/calorie ratio. Pyloric tonsil, involved in the chicken defense barrier, is a component of GALT. To evaluate the specific region, adult turkeys were taken from slaughterhouses. Crossman's modified triple staining demonstrated the general histological structure, PAS revealed the density of goblet cells synthesizing mucus, and Safranin O showed the capsule around the follicles. The width of lymphoid follicles in the pyloric tonsil (204.0±22.33) differed significantly from that of the middle part of the duodenum (111.7±4.741). It was noticed that the specific area harbors T cells, B cells, and follicular dendritic cells. Interfollicular regions were infiltrated with CD3+T cells, but the CD268+B cells occupied primarily germinal centers. However, it was noticed that T cells were present in germinal centers and some B cells in the interfollicular region. Anti-Vimentin antibody revealed follicular dendritic cells in the pyloric zone. It was noted that the epithelial layer of the pyloric tonsil is devoid of CK18-positive cells. Findings of the semi-thin section indicated that some columnar epithelial cells were stained differently in the transition zone (lymphoepithelium). To sum up, a pyloric region in turkeys is structurally dissimilar to pyloric tonsils detected in chicken, chukar partridge, and duck. More research is needed to reveal the effect of pyloric tonsil on the alimentary tract in poultry in terms of defense mechanisms.

The main objective of sperm production centers is to produce as many straws as possible from the obtained ejaculates using the optimal dilution rate. To this end, this study is the first to evaluate the effect of different semen extender rates on Anatolian buffalo semen quality. Ejaculates were collected by artificial vagina from three Anatolian buffalo bulls (n=105). These ejaculates were divided into three aliquots and filled into 0.25 ml straws with soy-based extenders at the concentrations of 35, 25, and 15 million spermatozoa/straw. The straw samples of different spermatozoa concentrations were frozen. The quality of spermatozoa was evaluated after thawing (37 °C, 30 sec) and following the thermoresistance test (37 °C, 3 h). The post-thaw total motility and progressive motility values were similar between the groups. However, following the thermoresistance test, there was a significant decrease in total motility in the 35 million spermatozoa/straw group, and the progressive motility was significantly higher in the 25 million spermatozoa/straw group. There was no statistically significant difference between the groups in terms of sperm kinetic parameters, except VSL after thawing except the VAP and LIN values following the thermoresistance test. In conclusion, it is recommended to dilute the Anatolian buffalo semen at a concentration of 25 or 100 million spermatozoa/ml per straw when freezing it with a soy-based semen extender. In addition, it is considered that soy-based extenders compensate for cryo-damage to sperm motility for a short time, and the thermoresistance test should be applied for objective evaluation in dose optimization studies.

The aim of this study is to determine and compare the distribution, localization, race, age and gender incidences of head and neck region tumors by years by evaluating the results of canine-cat biopsy and/or operation material brought to Ankara University Faculty of Veterinary Pathology Department between 2011-2021. In the study, 244 (15.9%) of 1533 tumors diagnosed in dogs and cats between 2011-2021 belonged to the head and neck region, of which 159 were in dogs and 85 in cats. Dogs with tumors were more than 6 years old (n=108) and cats were 1 year and older (n=75). In the head and neck region observed in dogs, malignant and benign tumors of epithelial origin were most common (n: 81; 50.9%), and sebaceous tumors (n: 22) were the most common epithelial tumors. Among the tumors of this region, epithelial tumors are mostly encountered in cats (n: 39; 45.8%), and 51.2% of the epithelial tumors are squamous cell cancer (n: 20), epithelial tumors are most common in the mouth (n: 12) and nose (n: 12). n:9) was observed.

Among the tumors of this region, epithelial tumors are mostly encountered in cats (n: 39; 45.8%), and 51.2% of the epithelial tumors are squamous cell cancer (n: 20), epithelial tumors are most common in the mouth (n: 12) and nose (n: 12). n:9) was observed.","PeriodicalId":7874,"journal":{"name":"Ankara Universitesi Veteriner Fakultesi Dergisi","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47355176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This study aimed to assess the efficiency of ketamine and medetomidine by two different doses and routes on anesthesia depth and cardiac stability in red-eared sliders. Each turtle was anesthetized two times, with seven days wash-out period. Induction of anesthesia consisted of a bolus combination of ketamine (10 mg/kg) and medetomidine (0.2 mg/kg) administered in the left brachial biceps in the intramuscular protocol, or a bolus combination of ketamine (20 mg/kg) and medetomidine (0.2 mg/kg) administered in subcarapacial sinus after clear blood presence confirmation in the intravenous protocol. Vital signs, reaction on the skin palpation, manual mouth opening for endotracheal intubation, palpebral and cloacal reflex, and the withdrawal reflex of the front and hind limbs were measured and recorded every 5 minutes for 60 minutes after anesthesia injection. Atipamezole (1 mg/kg) was administered in the right brachial biceps one hour after ketamine and medetomidine administration. Needle insertion and possible painful reactions to drug administration were also evaluated and recorded. Obtained data were analyzed for normality and paired t-tests, Wilcoxon, or McNamar tests were performed where appropriate. The values of P ≤ 0.05 were considered significant. A significantly less pronounced decrease in heart rate was observed with intravenous anesthesia protocol. Both protocols recorded complete anesthesia recovery 60 minutes after intramuscular atipamezole administration. A ketamine-medetomidine dose combination administered intravenously provides a more stable and consistent anesthetic plane in red-eared sliders than ketamine-medetomidine administered intramuscularly.
