African swine fever virus (ASFV) causes one of the most dangerous diseases of pigs and wild boar – African swine fever (ASF). Since its second introduction into Europe (in 2007), the disease has been spreading consistently, and now ASF-free European countries are at risk. Complex interactions between the host’s immune system and the virus have long prevented the development of a safe vaccine against ASF. This study analysed the possibility of neutralisation of the ASFV in vitro by sera collected from ASF-survivor animals. Two pig and three wild boar serum samples were collected from previously selected potential ASF survivors. All sera presented high antibody titres (>5 log₁₀/mL). Primary alveolar macrophages were cultured in growth medium containing 10% and 20% concentrations of selected sera and infected with a haemadsorbing ASFV strain (Pol18_28298_O111, genotype II). The progress of infection was investigated under a light microscope by observing the cytopathic effect (CPE) and the haemadsorption phenomenon. Growth kinetics were investigated using a real-time PCR assay. Haemadsorption inhibition was detected in the presence of almost all selected sera; however, the inhibition of virus replication in vitro was excluded. In all samples, a CPE and decreasing quantification cycle values of the viral DNA were found. Anti-ASFV antibodies alone are not able to inhibit virus replication. Interactions between the humoral and cellular immune response which effectively combat the disease are implicated in an ASF-survivor’s organism.

Danyer, Erdem | Bilal, Tanay
This sectional study aims to collect data about feeding practices for pace horses in the Aegean and Marmara regions of Turkey. For this purpose, a questionnaire consisting of 69 free text and multiple-choice questions was developed. The questionnaire was implemented on 29-31 August 2014 by personal interviews and was online on social media for ten months. The questionnaire comprised sections on breeder demographic information, farm condition, feeding habit, and nutritional disease. Fifty volunteer horse owners who had a total of 271 horses have participated in the study. Evaluation of the results focused on nutrition practices. Unfortunately, 46% of the respondents were not rasping their horses’ teeth, and an important part of them was not using supplementary oil (78%) or feed additives (84%). Drinking water after exercise (74%) as well as rotten, mouldy, and bacterially contaminated feed (72%) were reported as the most important colic reason by the responders. Based on the results of our study, educational initiatives are needed to inform pace horse owners about appropriate nutrition and related diseases to increase the pace horse race performance.

Yıldırım, Cağatay | Macun, Hasan Ceyhun
Adipokines are a group of proteins that are synthesized from adipose tissue. Omentin is a type of adipokine which is detected in human serum and it is evaluated as a secreted factor from adipose tissue, placenta and ovarium. The knowledge about the effect of omentin on reproduction is limited. In the presented study, investigation of omentin effect on in vitro uterine contractions was evaluated. The uteruses of the rats which were collected from 20 virgin female rats, were isolated and suspended in the isolated organ bath. The experimental protocols were carried out in 3 groups. The effect of omentin on spontaneous uterine contractions in protocol 1, induced by oxytocin (2.5 mIU/mL) in protocol 2, and induced uterine contractions with PGF2α (10-6 M) in protocol 3 was tested. The effect of omentin on isolated uterine tissues was tested with the administration of 10, 100 and 300 ng/mL omentin. 300 µL of distilled water was applied to the control of each group. In this study, 10, 100 and 300 ng/mL of omentin applied for 10 minutes did not have an effect on uterine contractility in all study groups (p>0.05). As a result, further studies with higher doses and longer incubation times are recommended.

Alıç Ural, Deniz | Ural, Kerem | Erdogan, Songul | Ayan, Adnan | Erdoğan, Hasan
In the present multidisciplinary study, the researchers on a field trial performed a Social Network approach and a group of 9 calves (3 males/6 females) aged 10 to 16 weeks. A 24 hours digital camera was used for location registration (X-Y position) and interactions on each calf, both individually and collectively. Based on the simple methodology nearest neighbor matrix positive and negative associations were analyzed. The field study lasted 4 weeks and the maximum interaction day was chosen, when individual calf activity was high. To those of 9 calves solely no 2 was infected with giardiasis on the first week, whereas calves with no:2, 7, and 8 were also infected on the second week. No: 4 and 6 were also infected with a total of 5 calves on the third week. This was followed by the final 6 calves in total infected. During the observation period, both by investigators and camera records, infected calf 2 was in close contact with no: 8 (at morning observation) and a slight degree of contact with no: 3 and 4 which were detected with giardiasis on the third and fourt weeks, respectively. Due to close contact with no: 8, infection was determined on the second week, earlier than others (except no: 7). Calves with no: 1 and 5 were never infected nor determined by PCR, fecal smear, or rapid diagnostic test kits throughout the study. In conclusion, the present authors suggested that social networking might be an important predisposing factor for giardiasis infection among calves.

The aim of this study was to determine the prevalence of Dirofilaria immitis (D. immitis) in dogs in the Ardahan region. The study material consisted of 100 Akbaş crossbred dogs (53 females and 47 males) between the ages of 3-7 in Ardahan region. An immunochromatographic analysis test kit was used to determine seroprevalence. The presence of antigen against D. immitis was determined as 12% (12/100). When the dogs with antigens against D. immitis were evaluated according to their age, it was determined that the highest positivity was in 4 years old (15%) (P˃0.05). Antigen presence against D. immitis was detected in 10.6% of male dogs and 13.2% of female dogs (P˃0.05). According to the data obtained from this study, it was concluded that D. immitis was seen in dogs in the Ardahan region and that protection and control measures should be taken for the eradication of this disease due to reasons such as global warming, wildlife and lack of education.

Deveci, Mehmet Zeki Yılmaz | İşler, Cafer Tayer | Altug, Muhammed Enes | Kırgız, Ömer | Yurtal, Ziya | Alakus, Halil | Alakus, İbrahim | Agyar, Zeynep Nur | Öründü, Nimet
Radial and ulnar fractures are common in small animals. Especially toy and miniature breed dogs are at high risk of incidence. Although there are plenty of studies on the treatment of radius and ulna fractures in small animals, studies related to the radius and ulna fractures in toy and miniature breed dogs are limited. The objective of this study was to report the diagnostic information and treatment outcome of radial and ulnar fracture treatment in toy and miniature breed dogs. Radius and ulna fractured 22 toy and miniature breed dogs were included in the study. Clinical findings, radiographic images, treatment applications, prognosis and outcomes were evaluated. As a treatment method, external coaptation in 5 extremities and surgical reduction and osteosynthesis in 17 extremities were performed. Out of 5 dogs who underwent external coaptation, 4 had good outcome and 1 had malunion. Out of 17 patients which underwent surgical treatment, 13 had a good outcome, 2 had nonunion, 1 had surgical site infection, and 1 had malunion and implant failure. As a result, original data on the etiology, diagnosis, treatment, prognosis evaluations, and surgical outcomes of radius and ulna fractures of toy and miniature breed dogs were presented. External coaptation considered could be successful in closed and undislocated radius and ulna fractures of toy and miniature breed dogs. However, the surgical approach and osteosynthesis performing are considered essential in dislocated, comminuted, complicated fractures, or open fractures. Further prospective studies are needed to compare specific surgical treatment methods.

2022
Ural, Kerem | Erdogan, Hasan | Erdogan, Songul
Present research was conducted at the University of Aydin Adnan Menderes, Faculty of Veterinary. In a total of 10 cats with pruritic dermatoses were allocated, classified [Feline atopic skin syndrome (FaSs)] and adapted to the retrospective case controlled study on the basis of Polycheck in vitro Allergy Test, clinical signs, dermatoscopic and cytological examination. No prior drug prescription, nor immunosuppressive treatment were evident, which was an inclusion criteria. Complete blood count, serum biochemistry, and endocrine panels were all deemed available on days 0 and 21 for all cats involved. The Feline Dermatitis Extent and Severity Index (FeDESI) and a 10 cm visual analog scale (VAS) were deemed available as relevant prognostic parameters. A three strain invoving soil-based probiotic used via rectal route significantly decreased FEDESI and VAS pruritus scores after 10 days of rectal use. Pre-treament day 0 FEDESI scores (median ± SD) (106.3 ± 41.38), were significantly higher than scores on day 10 (15.3 ± 10.53) switching the severity of the disease to mild status in all cases. Furthermore, day 0 VAS pruritus scores were 7.4 ± 1.78 (mean ± SD) (prior to treatment), whereas owner VAS pruritus score was decreased to 1.3 ± 1.06 (mean ± SD) significantly (p=0.005). It should not be unwise to draw preliminary conclusion that 3 chained soil-based Bacillus probiotic was capable of short term cure for FaSs. Bacillus probiotics with safety usage should be added to therapeutical armamentarium of FaSs.

Bulut, Osman
In this study, it is aimed to investigate the effects of intracameral mydriatic combinations on the pupil dilation (PD), intraocular pressure (IOP), heart rate (HR) and mean arterial pressure (MAP). In this study 35 animals were divided into 5 groups. The first group (MSic) was phenylephrine hydrochloride (Mydfrin) and cyclopentolate hydrochloride (Sikloplejin), the second group (TLic) was tropicamide (Tropamid) and 2% lidocaine, the third group (BSS) was balanced salt solution. Cats were anesthetized, and all solutions were injected intracamerally. The fourth group (MSt) was phenylephrine hydrochloride (Mydfdrin) and cyclopentolate hydrochloride (Sikloplejin) and the fifth group (TLt) tropicamide (Tropamid) and 2% lidocaine were given by topically. During this research, the fastest onset of the mydriasis was numerically formed by first group. All intracameral groups were seen having longer duration of mydriasis compared to topical groups. Intraocular pressure decreased after anterior camera paracentesis in all intracameral procedures. In our study, time dependent changes of heart rate were found to be statistically significant in all groups. Our research observed that first and second group successfully created enough mydriasis (>10mm). In terms of pupil diameter, it has been proven that first and second group are usable alternatives administration, and no side effects on intraocular pressure, heart rate or mean arterial pressure.

Orhan, Aylin | Bozkan, Zeynep
This study was aimed to determine whether the reference values affected by different times of the day and season in Saanen Goats. One hundred twenty-two goats were included to this study and, tear secretion (TS) and intraocular pressure (IOP) were measured in three different time periods as morning, noon and evening on the same day in each seasonal group. Temperature and humidity values were recorded during all measurements. There was no difference between the right and left eyes in terms of IOP and TS (p>0.05). While mean TS value was significantly increased in the winter group (12.23±0.28 mm/min) compared with the spring (9.9±0.18 mm/min) and summer (9.14±0.19 mm/min) groups (p<0.001), mean IOP was significantly decreased in the winter group (14.05±0.28 mmHg) compared with the spring (17.64±0.36 mmHg) and summer (17.32±0.43 mmHg) groups (p<0.001). While mean TS value was significantly increased at noon (10.08±0.28 mm/min) compared with morning (10.99±0.24 mm/min) (p<0.001), mean IOP was significantly decreased in the morning (14.95±0.31 mmHg) compared to the afternoon (17.63±0.35 mmHg) and evening (16.54±0.42 mmHg) (p<0.001). In conclusion, TS and IOP values in Saanen goats are affected by different times of the day and season, and it will contribute to the literature by determining the values that can be taken as reference for these different daytime and seasonal profile of the IOP and TS in Saanen Goat.

2022
Hassan, Muslimo Abdullahi Sheik | Karslı, Mehmet Akif
In this review, the use of some feed additives in the diets of ruminant animals is discussed. Brief information about the anatomy of the digestive system of ruminants and the metabolism of some nutrients in these animals are presented. In addition, summary information about some feed additives used in animal nutrition is given. Particularly detailed information about pre/probiotics among feed additives is presented, and the effects of S. cerevisiae, known as yeast, are discussed. In ruminant animals, unlike the monogastrics, feed additives, especially pre-and probiotics, are utilized to affect fermentation in the rumen. In addition, it is seen that it is used to increase immunity in pre-ruminants. However, it is obvious that more studies are needed on these issues.
