Pulsed-wave Doppler ultrasonographical measurements of supra-mammary lymph nodes for diagnosis of bovine mastitis

Ali RIŞVANLI

The aim of this study was to investigate the relationship between mastitis and supramammary lymph nodes in lactating cows in terms of Pulsed-wave (PW) Doppler ultrasonographical measurements. A total of 102 head cows in lactation period were divided into three groups. The cows in which all mammary lobes were California mastitis test (CMT)-negative (n 27) formed the 1st group; those with CMT-positive mammary lobe (n 43) formed the 2nd group and the cows with clinical mastitis in at least one mammary lobe (n 32) formed the 3rd group. In PW Doppler ultrasonography, end-diastolic velocity, systoli ...Daha fazlası
