    Comparison of glucose levels in blood samples taken from coccygeal, jugular and mammary vein of cows in lactation
    (Bursa Uludağ Üniversitesi, 2023-01-23) Akgül, Gülşah; Cihan, Hüseyin; Kasap, Sevim; Evci, Fatma Zehra; Şentürk, Sezgin; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Bölümü; 0000-0003-1544-6438; 0000-0001-9501-9983; 0000-0002-2767-7690; 0000-0002-2465-9913
    Blood glucose level is one of the most commonly used parameters in assessing the energy metabolism in dairy cows. The presented study aimed to compare the glucose concentrations in blood samples taken from the coccygeal vein, jugular vein, and mammary vein from the sameanimals at the same time. Healthy Holstein-Friesian dairy cows (n=25) in their second and third lactation were selected for the study. Theblood samples were taken from the coccygeal vein, jugular vein, and V. subcutanea abdominis (mammary vein) at the same time from eachanimal. To analyze blood glucose, Free Style Optium Blood Glucose Test Strip (Abbott, Istanbul, TURKIYE) was used. In comparison to theblood taken from both the jugular vein and coccygeal vein, glucose levels in blood samples taken from the mammary vein were significantly low (P<0.001). As a result, the determination of glucose levels in blood samples taken from the mammary veins may cause erroneous interpretations.The refore, the mammary vein for blood glucose must not be used as a sampling site.

    Comparison of the effects of buparvaquone and paromomycin on oocyst excretion and clinical parameters in diarrheal calves naturally infected with cryptosporidiosis
    (Hellenic Veterinary Medical Soc, 2022-10-01) Evci, Fatma Zehra; Şentürk, Sezgin; Evci, Fatma Zehra; ŞENTÜRK, SEZGİN; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı; 0000-0002-2767-7690; 0000-0002-2465-9913; HOR-5415-2023; JRN-6743-2023
    Cryptosporidium spp. is an obligate intracellular parasite that infects a wide variety of hosts. Young calves are particularly susceptible to infection. In the present study, we investigated the effects of buparvaquone and paromomycin on oocyte shedding and clinical parameters in calves naturally infected with cryptosporidiosis. Twenty calves with naturally occurring cryptosporidiosis were divided into two groups (n=10, each). A single dose of 2.5 mg/ kg buparvaquone was administered intramuscularly to one group, while the animals in the other group received 100 mg/kg/day paromomycin orally for seven days. On day 7, oocyst shedding (p<0.001) was reduced, and sucking reflex (p=0.002) and mental status (p=0.034) were improved in calves treated with buparvaquone. Our results suggest that applying a single dose of buparvaquone injection can be an excellent alternative to complex treatment methods applied to calves with cryptosporidiosis in the field regarding the economics and practicability.
