| description | This study was performed to investigate the possibility to use ultrasonography as a diagnostic tool for sub-clinical mastitis in dairy cows. Five cows with high cell counts, and four cows with low cell counts were selected as cases and controls, respectively, and their udders examined with ultrasound during a 5 week period. The image of the udders of cows with high cell counts exhibited small, hyper-echoic, rounded foci, approximately 1 cm in diameter, near the milk cisterns and the base of the teats. These changes were not found consistently in all cows with high cell count, however. Ultrasonography may be a valuable complementary tool in the diagnosis of sub-clinical mastitis in dairy cow, but more cases need to be monitored before its full value can be ascertained. |

Five cows with high cell counts, and four cows with low cell counts were selected as cases and controls, respectively, and their udders examined with ultrasound during a 5 week period.

Ultrasonography may be a valuable complementary tool in the diagnosis of sub-clinical mastitis in dairy cow, but more cases need to be monitored before its full value can be ascertained. För att undersöka möjligheten att använda ultraljud som hjälpmedel för att ställa diagnos vid subklinisk mastit hos kor undersöktes ett antal kor på Kungsängens gård i Uppsala med ultraljud. Kor med höga celltal och utan andra symtom valdes ut som försöksgrupp. Som kontrollgrupp valdes 4 kor med låga celltal. Försökskornas och kontrollgruppens juver ultraljudsundersöktes vid 5 respektive 3 tillfällen under en 5 veckorsperiod. På ultraljudsbilden hos de kor som hade höga celltal sågs små, ca 1 cm i diameter, ibland konfluerande hyperekoiska foci, i närheten av spenbasen och mjölkcisternen. Förändringarna sågs dock inte på alla kor med höga celltal och bilden förändrades något över tiden. Inga hyperekoiska foci var synliga vid något tillfälle hos kontrollgruppen. Ultraljud kan ha en framtida, kompletterande funktion inom mastitdiagnostiken men fler fall måste undersökas för att fastställa det diagnostiska värdet innan det tas i allmänt bruk.
