Abstract |
Macroscopic investigations were made on the lesions of a total of 101 udders from slaughtered Holstein cows in Gwangju area. Incidence of supernumerary teats was 9.9%. Gross lesions were found in the surface of teats of 29.4% of cows; these lesions comprised papilomatosis (16.0%), fronds (8.9%) and injury at the tip (3.2%). Approximately 95% of the cows had slight to severe teat orifice keratosis. On the mucous membranes of the teat cisterns, fibrosis (22.7%) and congestion (8.9%) were observed. Gross lesions were found in the mammary glands of 68% of cows; these lesions comprised fibrosis (18.8%), serous exudate (4.9%), fatty tissue (4.9%), pus (4.0%), congestion (2.0%). |
