ABSTRACT
The tissue structure of the mammary gland was examined with an Aloka SSD-500 ultrasound device
(Aloka Co., Ltd., Japan). The ultrasound images were binarized and the brightness level was determined
on a gray scale. Pixels with brightness values of 0 to 127 were assigned to the adipose tissue, and pixels
with brightness values of 128 to 255 were assigned to the secretory tissue. The results were recorded with
regard to the percentage of gray area in the total area. Highly significant correlations were found between
the percentage of secretory tissue and the milk yield of primiparous cows.
