Background: A regular and balanced feeding is essential for the animals in order to maintain their normal physiological function and be productive at the desired level. Digestion activities start with chewing in the mouth and the healthy dental arch is needed to perform a complete chewing function. Abnormal dental development and other dental pathologies impair digestive functions by negatively affecting chewing functions. The aim of the present study was to classified dental anomalies, dental degenerations, dental and gingival lesions seen in dairy cows and was aimed to reveal these lesions and depending on these disorders the reasons for slaughtering in dairy cows.Materials, Methods & Results: The material of this study consists of 600 dairy cows, being slaughtered for a year, and 170 dairy cows, detected dental anomalies, dental degenerations and dental-gingival lesions in the postmortem examination. Detailed macroscopic and radiological examinations of mandibles and maxillae of the dairy cows with dental and gingival lesions in postmortem examination were performed. The detailed information of the cases, such as: age, race, breeding, living region and slaughtering causes, etc. of dairy cows, suffering from dental lesions was recorded from slaughterhouse data access. In this study, 87 cases (51.18%) of the determined dental lesions were defined as dental degeneration, 34 cases (20%) as caries, 30 cases (17.64%) as dental abnormalities in the formation and dental arch and 19 cases (11.18%) as periodontal inflammation.[...]

Background: Oxidative stress plays an important role in the etiology and/or progression of various diseases in the livestock. The aim of this study was to investigate the relationship between foot diseases and oxidant and antioxidant levels, determining catalase (CAT) and glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA), nitric oxide (NO) and glutathione (GSH) concentrations in sheep with foot disease such as interdigital dermatitis, footrot and interdigital pouch infection (biflex canal inflammation).Materials, Methods & Results: In the study, a total of 70 sheep aged between 1 and 3, 20 sheep with interdigital dermatitis, 20 with foot-rot, 10 with interdigital pouch inflammation and 20 clinically healthy Akkaraman sheep, were used. The blood samples collected from the V. Jugularis of the sheep were centrifuged and their serums were obtained. MDA and NO levels of the sheep with interdigital dermatitis, footrot and interdigital pouch infection were found to be significantly higher than those of animals in the control group (P < 0.001). CAT activity was determined to be significantly lower in all diseased animals than in the animals in the control group (P < 0.001). GSH-Px and GSH levels were significantly lower in the animals with interdigital dermatitis than in the control group (respectively P < 0.001, P < 0.05).Discussion: Oxidative stress regulates the metabolic activity of some organs and plays an important role in productivity in livestock. The oxidative stress is reported that caused by the increase in the production of excessive free radicals resulting from the exposure of animals to various stress factors and by the weakening of the antioxidant defense has an important role in the pathogenesis of numerous diseases such as foot diseases. In the presence of various stress factors, the level of malondialdehyde (MDA) and nitric oxide (NO) increases. MDA is determine the degree of cellular damage in tissues.[...]
