Abstract

There is debate about possible antagonism between high milk production and reproductive performance in dairy cattle. However, many studies have used biased measures of reproduction or inappropriate statistical methods. The objectives were to examine the association of the level of production with reproductive performance at the herd and individual cow levels.
