Find specific details on this topic and related topics from the MSD Vet Manual. (2023). 10-12, via a virtual format. Also, the use of estrus synchronization has allowed producers to get more cows pregnant and subsequently start to put some selection pressure on fertility within their herds. This paper reviews the present trends in research on dairy cattle reproduction in the United States. Current advancements in reproductive management of dairy cattle reflect a greater comprehension of reproductive processes and the need to integrate the The featured column of the Dairy Cattle Reproduction Council's 2016 Platinum award winners for Reproduction Excellence (Feature Column) had herd 21-day pregnancy rates Finally, a biannual market survey conducted by Hoard’s Dairyman indicates that the reported use of natural service bulls for breeding dairy heifers increased by nearly 6% between 1990 and 1996 and was nearly 10% greater for dairy heifers than for lactating dairy cows (Hoards Dairyman, 1997). For example, the eighth revised edition of the Nutrient Requirements of Dairy Cattle (NASEM, 2021) describes a nutrient requirement as the daily amount of a certain nutrient necessary to meet a healthy Phenotypically, the relationships between behaviour, milk production, and reproduction were studied in different dairy cattle breeds. The Dairy Cattle Reproduction Council is focused on bringing together all sectors of the dairy industry – producers, consultants, academia and allied industry professionals – for improved reproductive performance. But, not all beef x dairy crossbred cattle meet expectations. Although dairy cattle typically are fed rations that supply adequate energy density during lactation, genetic drivers for milk production inevitably lead to a period of some negative energy balance postpartum, and dry-matter intake may be critically At the 2018 Dairy Cattle Reproduction Council annual meeting, Paul Fricke, University of Wisconsin – Madison professor of dairy science and extension specialist in dairy cattle reproduction, reviewed the progression of timed-artificial insemination (A.
