Factors affecting pregnancy maintenance in dairy cattle: A corpus luteum perspective

Abstract

This literature review investigates the relationship between ovarian abnormalities and the successful maintenance of pregnancy in dairy cows. Notable findings during US diagnostics in dairy cows include the presence of additional CL, cavitary CL and CL of various sizes. Each of these ovarian abnormalities may exert varying influences on the outcome of pregnancy, either favorably or less favorably. Furthermore, this review explores different diagnostic methods and their associations with fetal survival rates. Drawing from articles, reviews, and literature from studies conducted in various countries across the Euroatlantic region, this review underscores the critical importance of precise pregnancy diagnostics in dairy cattle.
