The aim of this study was to determine dynamic thiol-disulphide homeostasis (TDH) parameters and ischemia modified albumin (IMA) levels in calves with neonatal diarrhea and compare with healthy controls. A total of 50 calves were included in the study. There were 25 calves in both diarrhea and healthy groups. Serum native thiol, total thiol, disulfide and IMA amounts were measured using new methods. Native thiol (p=0.025) and total thiol (p=0.041) values decreased significantly in calves with neonatal diarrhea compared to the healthy control group. Disulphide (p= 0.133), % disulphide/native thiol ratio (p=0.001) and IMA (p=0.0018) parameters were lower in healthy group, and the difference between the two groups was significant for the parameters other than disulphide. This study shows that TDH is impaired in neonatal calf diarrhea and IMA levels are increased due to oxidative stress.

Monitoring biomarkers related to inflammation and oxidative stress is critical in dogs because parvovirus causes both inflammatory and antioxidant alterations. The aim of this study was to investigate inflammatory and antioxidant changes caused by canine parvoviral enteritis to better understand the oxidative stress process related to this disease. Thus, the total thiol, native thiol, disulfide, and ischemia-modified albumin levels of Canine parvovirus infected symptomatic puppies and healthy puppies were examined. Using the results of complete blood counts, the blood serum thiol-disulfide homeostasis and ischemia modified albumin levels of the puppies with Canine parvoviral enteritis (n = 65) and the healthy puppies (n = 34) were compared. Canine parvoviral enteritis and control groups showed a statistically significant difference in thiol disulfide levels (p < 0.01), while no significant difference was observed in ischemia modified albumin levels between the two groups. As a result of this study, a picture contradictory to the literature information was discovered; it is believed that integrating research on oxidative stress at various stages of disease progression, including the early stage, clinical period and recovery processes may provide more information about the dynamics of oxidative stress during disease progression.

Objective: This study aims to compare the colostrum quality of Akkaraman and Merino ewes using refractometric measurements. Material-Method: The study material consisted of colostrum samples obtained from Akkaraman and Merino ewes reared under the continental climate of Ankara. The ewes were housed in separate barns on the same farm and received identical husbandry practices, feeding regimens, and synchronized lambing periods. Colostrum samples were collected within 4 hours postpartum via hand-milking into sterile polyethylene tubes. Samples were stored frozen until a target sample size of 50 per breed was attained, then thawed at room temperature before analysis. Brix values (%) of colostrum were determined using a digital refractometer (Milwaukee MA871, 0–85% range; Milwaukee Instruments, Inc., Rocky Mount, NC, USA). Colostrum quality was categorized as follows based on Brix values: 26% (good). Results: While half of the Merino ewes produced poor- or moderate-quality colostrum, 56% of Akkaraman ewes yielded good-quality colostrum. No statistically significant difference was observed in colostrum Brix values between the two breeds (p > 0.05). The minimum and maximum Brix values for Akkaraman ewes were 16.40% and 43.90%, respectively, whereas Merino ewes exhibited a range of 15.80% to 43.00%. The mean Brix value was 27.45% for Akkaraman ewes and 26.10% for Merino ewes. Conclusion: The colostrum quality of Akkaraman ewes was comparable to that of Merino ewes. These findings suggest that when compared to colostrum brix values of other breeds documented in the literature, Merino and Akkaraman breeds exhibit higher colostrum quality than dairy-type sheep but lower quality than meat-type sheep.

Kangal Shepherd Dogs are highly valuable working dogs unique to Turkey, known for their robustness in withstanding harsh climatic conditions and possessing advanced herd protection and management abilities due to their genetic characteristics. Haematological values serve as crucial indicators of the physiological and physiopathological parameters in animals. A complete blood cell count (CBC) emerges as a powerful diagnostic tool when appropriately assessed. Given the establishment of pure breeds, it is essential to acknowledge that breedspecific hematologic values may exhibit variations influenced by factors such as gender, lifestyle, age, and geographical location. Therefore, understanding the physiological distinctions between genders becomes paramount. This study aims to assess the impact of gender on the complete blood count in Kangal Shepherd Dogs. Upon comparing hematologic parameters between female and male Kangal Shepherd Dogs, a statistically significant difference was observed in the mean platelet volume (MPV) value, which was higher in females than males (p < 0.05). While the mean red blood cell (RBC), haemoglobin (HGB), and haematocrit (HCT) values were higher in males, no statistically significant results were found (p > 0.05)

The present study aimed to investigate the hematological and biochemical blood parameters, along with selected egg quality traits, of Turkish Sultan chickens. A total of 90 blood samples collected from 60-week-old hens and roosters and 129 eggs collected from 50 hens were analyzed. The findings showed that hematological parameters such as red blood cells (RBC), hemoglobin (HGB), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and heterophil-to-lymphocyte (H/L) ratio, as well as biochemical markers such as aspartate aminotransferase (AST), lactate dehydrogenase (LDH), and uric acid levels, were significantly higher in roosters. The average egg weight, shape index, yolk rate, and shell rate were 47.45 g, 75.14%, 33.46%, and 9.25%, respectively. The thick albumen rate was 41.42%, while the thin albumen rate was 15.86%. The internal egg quality traits were determined as follows: yolk index (45.84%), thick albumen index (5.82%), Haugh unit (70.09%), and yolk density (1.03 g/mL) and thick albumen density (0.98 g/mL). The highest correlation was observed between the Haugh unit and thick albumen height, as well as the Haugh unit and thick albumen index. Moreover, the lower shell thickness and Haugh unit values suggest that a shorter storage period may improve hatching performance. In conclusion, this study demonstrates for the first time the sex-related variations in hematobiochemical parameters, while establishing baseline egg quality traits of Turkish Sultan chickens.
