Publication Evaluation of passive transfer in goat kids with brix refractometer and comparison with other semiquantitative tests(Tübitak Bilimsel ve Teknolojik Araştırma Kurumu, 2019-01-01) Batmaz, Hasan; Kaçar, Yiğit; Topal, Onur; Mecitoglu, Zafer; Gümüşsoy, Kadir Semih; Kaya, Feyyaz; BATMAZ, HASAN; KAÇAR, YİĞİT; TOPAL, ONUR; Kaya, Feyyaz; Veteriner Fakültesi; İç Hastalıkları Ana Bilim Dalı; 0000-0002-1933-7354; 0000-0001-8820-1509; 0000-0003-1991-8957; 0000-0002-8389-4833; 0000-0002-5557-121X; AAH-1712-2021; AAH-4972-2021; IXN-7700-2023; AAH-1677-2021; S-8278-2017The aim of this study was to evaluate the passive transfer (PT) status of goat kids by Brix refractometry and compare the results with other semiquantitative tests (total protein - TP, glutaraldehyde coagulation test - GCT, and gamma-glutamyltransferase - GGT) and immunoglobulin G (IgG). The study was conducted on 75 goat kids born from 47 Saanen goats. The blood samples were collected from the kids on day 0 (presuckling) and on the 1st, 2nd, and 3rd days after birth. The Brix% and TP concentrations were measured with refractometers, and GGT activity was measured using a dry chemistry system. The duration of the GCT was determined in the first 60 min. The serum IgG concentration was measured by goat IgG ELISA kit. On the 1st and 2nd days, serum Brix% in the kids was measured as 9.33 +/- 0.17% and 9.17 +/- 0.14%, respectively. In the 1st and 2nd day serum samples of the kids, IgG was 817.76 +/- 37.34 mg/dL and 1173.29 +/- 47.81 mg/dL, respectively, and GGT was 1298.07 +/- 133.29 IU/L and 692.26 +/- 79.86 IU/L, respectively. The Brix refractometer was found to be more sensitive for detection of PT status in kids on the first and second days after birth, such as TP and GCT, whereas GGT, as an early indicator of PT, was useful only on the first day after birth. We conclude that the Brix refractometer could be used to determine the PT status in goat kids and Brix measurements lower than 8.6%, 9.2%, and 9.3% indicate failure of PT in 1-, 2-, and 3-day-old kids, respectively.Publication Evaluation of serum choline along with, some biochemical and clinical parameters in cattle suffering from with botulism(Pakistan Agricultural Scientists Forum, 2021-02-01) Batmaz, Hasan; Mecitoğlu, Zafer; Koç, Cansu; Kaya, Fatih; Topal, Onur; Cansev, Mehmet; BATMAZ, HASAN; MECİTOĞLU, ZAFER; KOÇ, CANSU; KAYA, FATİH; TOPAL, ONUR; CANSEV, MEHMET; Tıp Fakültesi; Farmakoloji Ana Bilim Dalı; 0000-0002-6097-5585; 0000-0001-8820-1509; 0000-0002-1933-7354; 0000-0003-2918-5064; M-9071-2019; AAA-4754-2022; IXN-7700-2023; S-8278-2017; HXD-1722-2023; FQB-3477-2022Botulism is a disease of cattle that causes significant impact due to its high mortality rate. The aim of the present study is to evaluate serum choline levels as well as clinical and biochemical parameters of cattle suspected to be suffering from botulism and to compare the results with healthy cattle and also to compare the results of survivors and fatalities. Thirteen botulism suspected and eleven healthy cattle were used. Total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), calcium, phosphorus, magnesium and potassium levels were measured from the sera of botulism and control cattle by colorimetric method using an autoanalyser. Choline levels were analyzed using HPLC. Dysphagia, decreased tongue strength weak anal reflexes, tongue and tail paralysis and locomotion disorders were the main clinical findings observed in suspected botulism cases. Botulinum toxin analysis of ruminal fluid samples were positive in two cattle from one herd. AST, ALT, potassium and choline levels were higher in cattle suffering from suspected botulism cases and choline levels were positively correlated with albumin and total protein levels. Three animals from botulism group survived. Clinical findings were milder, animals were not recumbent and choline levels were lower in survivors. Clinical findings of the three animals that recovered were milder, animals were not recumbent and choline levels were lower in survivors. It was observed that clinical findings such as decreased tongue strength and anal reflexes, dysphagia, tail paralysis, and locomotion disorders are important for diagnosis of botulism In conclusion, cattle with milder clinical signs and lower choline have a higher chance of survival.Publication Evaluation of passive transfer in goat kids with Brix refractometer and comparison with other semiquantitative tests(TÜBİTAK, 2019-01-01) Batmaz, Hasan; Kaçar, Yiğit; Topal, Onur; Mecitoğlu, Zafer; Gümüşsoy, Kadir Semih; Kaya, Feyyaz; BATMAZ, HASAN; KAÇAR, YİĞİT; TOPAL, ONUR; MECİTOĞLU, ZAFER; Kaya, Feyyaz; Veteriner Fakültesi; İç Hastalıkları Ana Bilim Dalı; 0000-0002-1933-7354; 0000-0001-8820-1509; AAH-4972-2021; AAH-1712-2021; IXN-7700-2023; AAH-1677-2021; S-8278-2017The aim of this study was to evaluate the passive transfer (PT) status of goat kids by Brix refractometry and compare the results with other semiquantitative tests (total protein - TP, glutaraldehyde coagulation test - GCT, and gamma-glutamyltransferase - GGT) and immunoglobulin G (IgG).

Moreover, the effects of these compounds on body weight gain and biochemical metabolism of pregnant ewe was assessed. A total of 59 pregnant Kivircik crossbred ewes were used in this study. Group I (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 1-week intervals. Group II (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 3-day intervals. Group III (n: 15) was administered 0.9% NaCl three times before delivery at 1-week intervals. Group IV (n: 14) was administered 0.9%NaCI three times before delivery at 3-day intervals. Six blood samples Were taken from each ewe four times before delivery and two times after delivery. Haematological and biochemical analyses were performed.The levels of BHB and NEFA in groups administered butaphosphan and cyanocobalamin were noticeably lower but there were no statistically significance. Elevated BHB (>0.8 mmol/L), subclinical pregnancies toxaemia were identified in 56.66% in test groups and 72.41% in control groups in all ewes and this was higher in the ewes bearing multiple pregnancies 71.42 in test groups and 82.35% in control groups. Subclinical pregnancy toxaemia in pregnant ewes with twins or triplets is lower than the levels for the control groups, despite the greater lamb counts and weights of the ewes in test groups.Based on our results, it was concluded that the butaphosphan and cyanocobalamin combination could be used as an alternative treatment for the prevention of pregnancy toxaemia.

Elektronik posta ile gönderilen ankete yedi farklı coğrafi bölgedeki 56 ilden toplam 326 veteriner hekim katılmıştır. Kendilerine bu alanla ilgili 19 soru sorulmuştur. Çalışma sonuçları genel olarak değerlendirildikten sonra veriler; veteriner hekimlerin çalışma şekline göre 3 grup, yaşlarına göre 4 grup ve coğrafi bölgelerine göre 3 grupta ele alınmıştır. Sığırcılıkla ilgili en önemli sorunlar; sırasıyla yem fiyatları, yetiştiricinin kar edememesi, üretici süt-et fiyatlarının düşüklüğü, mera sorunu, kırsal bölgeden göç, hastalıklara bağlı kayıplar ve kuraklık olmuştur. Koyun-keçi yetiştiriciliğinde en önemli sorunlar; sırasıyla mera, yem fiyatları, kuraklık, yetiştiricinin kar edememesi, üretici süt-et fiyatlarının düşüklüğü ve hastalıklardır. Veteriner hekimlerin %83,13’ü bölgelerindeki hayvan sayısının azaldığını ve %60,68’i ise 6-30 sığır kapasitesinde olan işletme grubundan azaldığını belirtmiştir. Meslektaşların %56,31’i hayvancılığın sürdürülebilir karlı olma olasılığının %25’in altında ve %20,92’si hiç karlı olmayacağı görüşündedir. Veteriner hekimlere gelir düzeylerinin geçmiş yıllara göre değişimi sorulduğunda %58,77’si olumsuz ve %29,23’ü kısmen olumsuz olarak değerlendirmiştir. Gelecek 10-20 yıldaki ruminant hekimliği hakkında %49,39’u olumsuz ve %33,44’ü kısmen olumsuz düşünmektedirler. Meslektaşlarımızın %63,80’i kendi çocuklarının veteriner hekim olmasını istememektedir. Önümüzdeki 10 yıl içerisinde gelişme potansiyeli en yüksek alanlar sorulduğunda pet sektörü %41,01, biyoteknoloji %17,03, sürü sağlığı %15,77, organik tarım ve hayvancılık %15,46, halk sağlığı %7,26, hayvan refahı %3,47 olarak yanıtlanmıştır. Sonuç olarak; veteriner hekimler ruminant hayvancılığının küçüldüğünü ve ruminant hekimliğinin daralacağı görüşündedirler.
