Abstract
This thesis reviews an extensive research program on the fertility of dairy catt1e in New Zealand. Most of the work was completed between 1967 and 1977. It involved studying numerous basic aspects of reproductive physiology by analysing extensive amounts of data either lodged within a large centralised recording system, or produced through the participating cooperation of herd owners or inseminators. New concepts were developed and old recommendations sometimes found to be inappropriate.
