An investigation of families and breeding lines of Holstein-Friesian cattle in relation to advanced registry records

De Kol 2d, Pietertje Hengerveld and Belle Koendyke each have two daughters. For each daughter the following number of grand daughters are found. For Belle Korndyke 93.5, De Kol 2d 81.5 , and Pietertje Hengerveld 60.5. The following number of great-grand-daughters may be attributed to each grand-daughter: De Kol 2d 5.29, Belle Korndyke 3.11 and Pietertje Hengerveld 2.96. This shows De Kol 2d was more prepotent over her great-grand-daughters or her daughters were bred to better sires.

The percent of the progeny found in each class clearly shows the prepotency of the progenitor.

The most noticeable influence over the grand daughters of the first class was that of Belle Korndyke, having 16.52% of progeny in first class. De Kol ranked second and Pietertje Hengerveld third.

In class two Belle Korndyke ranks first, De Kol 2d second, and Pietertje Hengerveld third.

In classes three and four some change is order is noticeable; Pietertje Hengerveld ranks first, De Kol 2d second, and Belle Korndyke third. / Master of Science
