    Abomasal impaction due to sand accumulation in two cows
    (Sivar-Soc Italiana Veterinari Animali Reddito, 2015) Simsek, A.; Sekin, S.; Icen, H.; Kochan, A.; Celik, O. Y.; Yaman, T.
    Introduction - Abomasal impaction is rarely encountered in cattle and is characterized by the drying of the abomasal content and the enlargement of the abomasum as a result of the abnormal accumulation of solid matter in the organ. Aim - This manuscript aims at reporting the occurrence of the rarely encountered abomasal impaction in Turkey. Materials and methods - Two five-year-old dairy cows presenting with symptoms of inappetence, lethargy and constipation constituted the material of the study. Based on the clinical symptoms and necropsy findings, the animals were diagnosed with abomasal impaction. Result and discussion - The body temperature, heart rate and respiratory frequency of the animals, which were slightly dehydrated, were within the normal ranges. Abdominal auscultation revealed reduced rumen contractions and bowel sounds were not heard. On palpation of the right abdominal wall, a large and hard mass was detected, while percussion was associated with a moaning sound. Post-mortem examination revealed the presence of a blood-tinged, dry abomasal content of hard consistency, composed of roughage and foreign substances, including soil, sand and gravel. Conclusion - In animals given feed and water containing mud or sand, sand may accumulate in the abomasum and lead to fatal impaction cases, resulting in significant economic losses. Animals displaying signs of chronic weight loss, ruminal tympany and constipation are recommended to be evaluated for abomasal impaction.

    Determination of the Relationship of Serum Amino Acid Profile with Sex and Body Weight in Healthy Geese by Liquid Chromatography-Tandem Mass Spectrometry
    (Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2022) Yavuz, E.; Iiak, K.; Celik, O. Y.; Bolacali, M.; Ergiden, Y.; Gurgoze, S.
    The aim of this study is to determine the serum amino acid profile using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS / MS) in healthy male and female geese of the same age that were raised in similar care and feeding conditions. The animal material of the study consisted of a total of 41 geese, 18 male, and 23 female of the same age (9 months). After a 12h fasting period of the geese, blood samples were taken from V. subcutanaeulnaris into tubes without anticoagulant. After separating the serums, the samples were preserved at -20 degrees C degrees until Methylglutaryl (Met-Glu), Valine (Val), Leucyl-Isoleucine (Leu-Ile), Methionine (Met), Phenylalanine (Phe), Argininosuccinate (ASA), Tyrosine (Tyr), Aspartic acid (Asp), Alanine (Ala), Arginine (Arg), Citrulline (Cit), Glycine (Gly), Ornithine (Orn), Glutamic acid (Glu) were analyzed. The Val, Asp, Arg, Cit, Gly, and Orn levels of male geese were higher compared to female geese in the research (p<0.05). It was determined that Asp, Arg, Cit, and Gly levels increased as the body weights of the geese increased (p<0.05). It was also determined that the effect of Gender x Body Weight interaction on Val, Cit, and Orn levels was significant (p<0.05). As a result; it has been concluded that the serum amino acid profile of healthy geese can vary according to gender and live weight, and more studies are needed to elucidate the reasons for these changes.

    Investigation of the effects of live weight and sex on oxidative stress and antioxidant parameters in healthy geese - preliminary study
    (Eugen Ulmer Gmbh Co, 2023) Yavuz, E.; Irak, K.; Celik, O. Y.; Bolacali, M.; Ergiden, Y.; Tufan, T.; Gurgoze, S.
    This study was carried out to determine the effects of live weight and sex on oxidant respective antioxidant status in clinically healthy geese. The total antioxidant level (TAS), total oxidant level (TOS), oxidative stress index (OSI), ferric ion reducing agent antioxidant power (FRAP) and Glutathione (GSH) levels were measured in serum samples from a total of 41 geese (18 males and 23 females) at 9 months of age, bred under the conditions of local breeders. While it was determined that live weight and sex had an effect on TOS and FRAP parameters, but it did not affect TAS, OSI and GSH values in geese. A negative relationship between live weight gain and TOS levels was found. It was detected that FRAP levels were higher in female geese than in males (p < 0.05). It was concluded that the relationship between TOS level and live weight of healthy geese should be further investigated and that the FRAP level could be evaluated as an indicator of antioxidant power in healthy geese of different sexes.

    Prevalence of Dirofilaria immitis, Ehrlichia canis, Borrelia burgdorferi Infection in Dogs from Diyarbakir in Turkey
    (Academic Journals Inc, 2011) Icen, H.; Sekin, S.; Simsek, A.; Kochan, A.; Celik, O. Y.; Altas, M. G.
    The aim of the present study was to determine the prevalence of Dirofilaria immitis antigen, Ehrlichia canis and Borrelia burgdorferi antibodies, using an Enzyme-linked Immunosorbent Assay (ELISA) (Snap 3Dx test; IDEXX Laboratories, Westbrook, Maine, USA). Study was performed on total of 82 mixed-breed dogs (60 female and 22 male). Each dog was examined clinically, microscopic examination of stained smear. D. immitis antigen infection was detected in 2 dogs (2.4%) and E. canis antibodies were present in 4 dogs (4.8%). None of the tested dogs (82) was positive for B. burgdorferi antibodies.
