Diagnosis of early pregnancy and embryonic mortality by means of ultrasonography in the cow

Research output: Contribution to journalArticle

Abstract

An optimum interval from calving to conception of 85 to 115 days requires intensive management activities during the first 100 days after calving. Early postpartum breeding in dairy cows results in more calves and higher milk production per lactation, but early bred cows require more inseminations and have a greater occurrence of embryonic mortality (Britt 1975). Accurate early detection of pregnant and non-pregnant cows and cows with late embryonic mortality plays a key role in achieving an optimum calving to conception interval. Recently, it was demonstrated that pregnancy testing by means of ultrasonography after Day 30 can result in shorter calving intervals (Baxter & Ward 1997).
