Abstract
On the basis of measurements derived from 9344 primiparas, regression correlation was calculated between conformation traits and milk performance. An increase of 1 cm in the height at the back and at withers as well as chest circumference resulted in milk yield increase of approximately 50 kg and fat and protein yield increase of about 2 kg per lactation. The assessed regression interrelationships were highly significant.
