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.
