As a result, healthy poultry eye examination reference values are crucial for early disease diagnosis. Schirmer tear test I (STT I), intraocular pressure (IOP), and central corneal thickness (CCT) of 48 eyes (24 right and 24 left eyes) of 24 healthy male Broiler’s were measured under European Union standards (20 lux light intensity and 80% of the used area is illuminated indoor). Routine ophthalmological examinations, including reflex tests (pupillary, palpebral, threat, light) and direct ophthalmoscopy for the eyelids, conjunctiva, cornea, iris, lens, and fundus, were performed following physical and clinical evaluations of all animals. Standard Schirmer test paper was used for the STT I test. Rebound tonometry was used to determine the IOP value. A pachymeter has been used to obtain CTT measurements. The measurements for the right and left eyes were performed separately. STT I values of the right (n=24), left (n=24), and right+left (n=48) eyes as mean±standard error were 9.75±0.79 mm/min, 6.67±0.20 mm/min and 8.21±0.46 mm/min, respectively. As a mean standard error, the IOP measurements of the right (n=24), left (n=24), and right+left (n=48) eyes were 12.210.50 mmHg, 11.670.50 mmHg, and 11.940.36 mmHg, respectively. The CCT values (mean±standard error) of the right (n=24), left (n=24), and right+left (n=48) eyes were 265.46±7.42 μm, 285.92±10.46 μm, 275.69±5.17 μm, respectively. A statistically significant difference was observed between the STT I values of the right (9.75±0.79) and left (67±0.20) eyes (p<0.05). A statistically significant positive correlation was found between right and left eye IOP measurements (r= 0.525, p<0.005). According to the results, identifying the healthy eye reference values of Broiler poultry breeding may be helpful for early disease detection and the sustainability of poultry production.

The owner reported that the calf was purchased from an auction 1 month ago and the calf was having difficulty urinating. The calf was depressed, and crusty painful masses were found in the prepuce. Blood urea nitrogen and serum creatinine concentrations were within reference ranges. Radiographic imaging revealed urolith deposition in the prepuce, and the preputial orifice was obstructed with a urolith. Cystocentesis was carried out and uroliths were removed using local infiltration and regional anaesthesia. The analysis of the mineral composition indicated that the uroliths' composition was uric acid. Forceps were used to carefully manipulate the urolith to remove it from the obstructed preputial orifice. The animal had a perfect recovery 1 week later.

Bite wounds and traffic accidents are common causes. This study aimed to describe a successfully treated case of bilateral lip avulsion and mandibular symphyseal separation in a cat. The cat's owner claimed that the animal underwent two unsuccessful surgeries in nearby veterinary hospitals after being injured in a car accident a month earlier. Euthanasia was recommended in every clinic and hospital the animal's owner visited, therefore the owner decided to bring the animal to the faculty hospital. Hemimandibles were separated from each other and the cat was depressed during the examination. Lips were avulsed bilaterally from the mandibles, puss and food remnants were observed in the avulsed areas. The cat was anesthetized and the avulsed areas were flushed and debrided. A cerclage wire was knotted between the canine and premolar teeth to secure the hemimandibles. The buccal area's mucosal layer was sutured to the ventral palatal areas to relieve suture tension. Meloxicam, pantoprazole, amoxicillin-clavulanic acid, and chlorhexidine were recommended for 7 days, as well as an Elizabethan collar, liquid feeding, and weekly control visits for 2 months. Sutures and the wire were removed on the postoperative 14th and 60th days. The animal recovered perfectly without any complications after two months. Preoperative interventions and proper surgical planning that takes into account the forces on the tissues and the locations of the separation and dehiscence lead to success in challenging cases.

Objective
The objective of the present study was to examine the effect of different light intensities on tear production, corneal thickness, and intraocular pressure in broilers.
Animals studied
Both eyes of 72 male broilers were evaluated in this study.
Materials and Methods
Broilers were divided into the following three groups: low light intensity (n = 24, 5 lux), moderate light intensity (n = 24, 20 lux), and high light intensity (n = 24, 80 lux). The eyes of all birds (n = 72) underwent a complete ophthalmic examination, which included the Schirmer tear test (STT-I), intraocular pressure (IOP), and the central cornea thickness measurement (CCT). The effect of light intensity on the Schirmer test, intraocular pressure, and central corneal thickness values was examined at eye and animal level (right and left eyes separately and cumulatively/no distinguishing left or right) by using one-way ANOVA.
Results
At the animal level, without discrimination of left and right eye measurements, statistically significant differences were found between 5–20 and 20–80 lux groups on IOP measurements (p < .05). The difference in CCT measurements between the 5 and 20 lux groups was statistically significant (p < .05), and the corneal thickness of the 5 lux group animals was found to be statistically significant and higher than the 20 lux group (p < .05).
Conclusions
In conclusion, light intensity has an influence on eye health in broilers. Present results may attribute to the future studies as a reference value for broilers raised under different light intensities.

This case report aimed to describe the clinical findings and treatment results of a traumatic membranous urethral rupture in a 15-dayold Ambling foal. The foal had been wounded by a wild animal 9 days before, and despite treatment, the foal's condition worsened, the owner brought the animal to Faculty of Veterinary Medicine Research and Practice Animal Hospital. On physical examination several wounds in the pubic and inguinal regions were identified, some of which were complicated by a fistula. Vital parameters of the foal were not in reference ranges. In laboratory findings, lymphopenia, eosinopenia, mild anemia, and decreased partial oxygen pressure with acidic blood pH were observed. Sutures were applied surgically under general anesthesia to the urethral tear and wound care was provided. On the fifth day after surgery, the owner called the hospital to report that the foal was constipated and had signs of colic. Per rectal olive oil usage was recommended, and surgery was re-planned for the following day. Despite cardiac resuscitation and emergency treatments, the foal died during the operation due to cardiac arrest. In conclusion, gastrointestinal outcomes of surgery and anesthesia must be considered.

This study enhanced the present knowledge about association between the claw conformations (CC), hindlimb conformation (HiLC), gait, and body condition score (BCS) in dairy cows. A total of 166 lactating Holstein cows were enrolled in the study and scored for BCS, CC, HiLC, and gait. The abnormal HiLC group was statistically significant (P<0.001) to have more abnormal CC. Hock in (Hin) cows showed significance (P<0.001) with CC abnormalities. Cows with abnormal gait have less abnormal claw and limb conformation than normal cows (P=0.032). Lactation number (P=0.036) and abnormal HiLC (P<0.001) were significantly increased risk for CC. The present results might be useful for claw and hindlimb conformations, and breeding strategies of the herd.

This study aimed to investigate the effects of St. John's wort oil on excisional full layer skin wound healing in mice.
Material and Methods: For this aim, 6-week-old male, 15 BALB / c rats were used. The mice were divided into 3 groups St. John's wort oil, olive oil, and physiological saline, each group of 5 mice. On the back skin of each mouse, six full-layered excisional skin wounds were created under anesthesia. The wound areas were photographed on a routine basis and the daily shrinkage of the wound area was observed with image processing techniques at three-day intervals in order to track and record the wound healing processes. On the 22nd day, wound tissues were collected and hydroxyproline and total protein levels were determined using an ELISA method.
Results: The wound healing time, wound closure amount, hydroxyproline, and total protein levels between the groups were not statistically significant (p> 0.05).
Conclusion: Based on the present study, St. John's wort oil does not have a negative effect on wound healing, also it does not speed up wound healing.

Digital dermatitis (DD) is a common infectious disease that causes economic losses and lameness. ... more Digital dermatitis (DD) is a common infectious disease that causes economic losses and lameness. In order to keep DD under control, the usage of footbath is very important in intensive dairy farms. It was aimed to determine the relationship between footbath use and the number of active lesions related to DD. In total of 1527 cattle from 6 dairy farms were included in the study to assess and correlate the prevalence of DD and footbath practices. Information about the farm structure and management practice of footbaths was obtained through a questionnaire. It was inspected all feet of cattle with DD lesions during the milking time and scored the lesions using six M-stages. Thereafter, the chi square test was performed to investigate the relation between digital dermatitis prevalence and footbath applications. DD lesions in 500 feet (8.2%) of 338 (22.1%) was observed in dairy cows. Farms using dry manure as a bedding material showed a higher DD prevalence (p<0.001). Farms using formalin footbath had the lowest DD lesions, whereas copper sulfate (CuSO 4) practice had the highest prevalence (p<0.001). Periodically renewed footbaths showed a statistically lower DD prevalence in farms (p<0.001). We concluded that the convenient design and management of footbath might help to reduce the prevalence of digital dermatitis in dairy farms.

Lameness may also be related to housing and animal-based factors. In this regard, this study aimed to investigate the relationship between potential risk factors with lameness and claw lesions in dairy farms. Eleven dairy farms with 1685 cows were enrolled in this study. Relationships between lameness existence with hind limb conformation, claw conformation, days in milk (DIM), lactation number (LN), bedding type, claw trimming intervals, and relationships between infectious claw diseases (digital dermatitis-DD and heel erosion-HE) with LN, DIM, bedding type, footbath existence, footbath chemical, footbath changing frequency, and footbath solution volume per cow were investigated. A binary regression model was used to reveal relationships. There was no statistically significant difference in the relationship between cow breeds and lameness score, hind limb conformation, claw conformation, and claw diseases. A positive correlation between the existence of lameness with all risk factors was found. Cows with abnormal hind limb and claw conformation numbered 220 and were 2.3 times more prone to lameness (P<0.001), respectively. A positive correlation was found between infectious claw diseases with LN, DIM, bedding type, footbath chemical, and footbath changing frequency. However, a negative correlation was found between infectious claw diseases and footbath solution volume per cow. The relationship between the infectious claw disease existence with DIM and LN was found to be statistically significant (P<0.001). Also, an increase in LN and DIM were found to increase the risk of infectious claw lesion frequency by 3.3 and 2.2 times, respectively. Findings suggest that abnormal hind limb and claw conformations should be more closely monitored and investigated in terms of lameness. LN and DIM should also be monitored in terms of infectious claw diseases. The result of the study may help farmers to specify their potential animal and management-based risk factors related to lameness and infectious claw lesions in their farms.

In the present study potential usefulness of infrared thermography (IRT) as a non-invasive instrument for rapidly screening the claw sole temperature alterations between baseline (before trimming) and after trimming was investigated. For this purpose, this study was aimed to reveal the effect of claw trimming on claw sole temperature by using infrared thermography (IRT). One hundred thirty IRT observations from the hind legs of non-lame, healthy cows were collected and examined from 65 cows. The maximum (Tmax), average (Tave), and minimum (Tmin) temperatures of the claw sole and the temperature difference (ΔT) between the lateral and medial claws were examined on the baseline and after trimming. Claw temperature values were evaluated for normality using the Shapiro Wilk test. Paired t-test was used for comparing results with normal distribution while Wilcoxon's signed-rank test was also used for nonparametric comparisons. Average baseline and after trimming solar surface temperature values on lateral claws were determined as 19.91±2.67°C and 21.49±3.43°C, respectively. The solar surface temperature values on medial claws were baseline 19.96±2.52°C and after trimming 20.98±2.83°C. There were statistically significant differences between baseline with after trimming solar surface temperatures of lateral (Tmax: P=0.005; Tave: P<0.001; and Tmin: P=0.005), and medial claws (Tave: P<0.001). After trimming, claw sole temperature values between the lateral and medial were statistically significant (Tmax: P=0.020; Tave: P=0.039; and Tmin: P=0.004). Medial-lateral claw temperature differences between baseline with after trimming values were also statistically significant (ΔTmax: P=0.050; ΔTave: P=0.001; and ΔTmin: P=0.019). In conclusion, claw trimming increased the solar surface temperature values of the claw sole in this study. In the present study, claw sole temperature values were relatively higher on lateral than medial claws both for the baseline and after trimming. In future studies, the reliability of the current method can be demonstrated by comparing thermography to other evaluation methods.

Bulg. J. Vet. Med. (online first). Six shelters with 7,468 animals (2,305 cats and 5,163 dogs) were followed and diseases and shelter welfare conditions were recorded for one year. Disease records were obtained and categorised on three headings (surgery, internal medicine, and reproductive diseases and interventions) and subheading categories. Descriptive statistics was used to reveal disease distribution, which can attribute to surveillance data. To evaluate shelter welfare conditions, a protocol was developed and shelters were assessed. Under the surgical disease category, the most encountered disease records were open wounds (502, 59.41% and 175, 31.99%) for dogs and cats. For the internal medicine category, the most encountered were respiratory system diseases both for dogs (917, 33.26%) and cats (351, 58.21%). Under the reproductive disease category, the most common disease in dogs was orchitis (29, 60.42%). In cats, the most encountered disease was metritis (19, 79.16%). Ordinal logistic regression was used for evaluation of associations between diseases and shelter conditions. For dogs, with a onepoint increase in shelter score, the odds of encountering reproductive diseases increased by 1.4%, while the odds of cumulative and internal diseases decreased 1.1 and 1.2 times (P<0.05) respectively. For cats, with an increase in shelter scores, the odds of encountering reproductive and cumulative diseases increased by 3.4% and 0.2%, respectively (P<0.05). Disease surveillance and their relation with shelter conditions may be helpful to design efficient plans in shelters.

Objective
The objective of the present study was to examine the effect of different light intensities on tear production, corneal thickness, and intraocular pressure in broilers.
Animals studied
Both eyes of 72 male broilers were evaluated in this study.
Materials and Methods
Broilers were divided into the following three groups: low light intensity (n = 24, 5 lux), moderate light intensity (n = 24, 20 lux), and high light intensity (n = 24, 80 lux). The eyes of all birds (n = 72) underwent a complete ophthalmic examination, which included the Schirmer tear test (STT-I), intraocular pressure (IOP), and the central cornea thickness measurement (CCT). The effect of light intensity on the Schirmer test, intraocular pressure, and central corneal thickness values was examined at eye and animal level (right and left eyes separately and cumulatively/no distinguishing left or right) by using one-way ANOVA.
Results
At the animal level, without discrimination of left and right eye measurements, statistically significant differences were found between 5–20 and 20–80 lux groups on IOP measurements (p < .05). The difference in CCT measurements between the 5 and 20 lux groups was statistically significant (p < .05), and the corneal thickness of the 5 lux group animals was found to be statistically significant and higher than the 20 lux group (p < .05).
Conclusions
In conclusion, light intensity has an influence on eye health in broilers. Present results may attribute to the future studies as a reference value for broilers raised under different light intensities.
Material and Methods: For this aim, 6-week-old male, 15 BALB / c rats were used. The mice were divided into 3 groups St. John's wort oil, olive oil, and physiological saline, each group of 5 mice. On the back skin of each mouse, six full-layered excisional skin wounds were created under anesthesia. The wound areas were photographed on a routine basis and the daily shrinkage of the wound area was observed with image processing techniques at three-day intervals in order to track and record the wound healing processes.
