    The objective of this study was to determine the differences between the healthy Holsteın-Friesian, Jersey, Simmental, and Aberdeen Angusbreeds Beta-hydroxybutyrate (BHBA) levels at the first three weeks after calving. The blood samples were collected for analysis between 10-20 days postpartum. In this study, 80 animals were used in different regions in total. BHBA was analyzed by Ketosite® (Ketosite®, Stanbio LabrotoryInc., Boerne, TX USA). Milk fat and protein levels were immediately measured by an electronic milk analyzer (Milkoscan FT1 FOSS Industries, Denmark). Statistical analyses of the study were performed using Sigma Plot 12 (Systat Software Inc., San Lose, CA). The means of BHBA levelswere compared by One Way Anova. As in Holstein cows, blood BHBA levels increased in the early lactation period and also in other breeds. Theresults of this study presented that serum BHBA levels were significantly higher in Holsteın-Friestein cows than in Simmental and AberdeenAngus cows.

    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.
