H. Allen and Ann Tucker Lectureship Seminar Series
Date: March 24, 2014
Location: H. Allen and Ann Tucker Lectureship Seminar Series 1240 Anthony Hall
Milo Wiltbank, professor in the Department of Dairy Science at the University of Wisconsin will present: The Tangled Web of Physiology, Management, Genetics, and Nutrition that Underlies Reproductive Efficiency in Dairy Cattle on Monday, March 24 from 11:30 a.m.-12:30 p.m., in 1240 Anthony Hall.
The seminar is sponsored by the H. Allen and Ann M. Tucker Lectureship in Animal Science.
Wiltbank earned his bachelor’s degree in zoology and master’s degree in zoology/physiology from Brigham Young University. He earned his doctorate from the University of Michigan, and completed postdoctoral training at Colorado State University.
His research focuses on the interaction of genetics and nutrition with reproduction in dairy cattle with special emphasis on ovarian function and embryo mortality. Wiltbank has published 179 refereed journal articles and served as director of the Society for Study of Reproduction and USA Representative for International Congress on Animal Reproduction. He is a recipient of prestigious awards such as the Merial Dairy Management Award and Pharmacia Physiology Award from the ADSA, the Research Award from the National Association of Animal Breeders, and the Service to Agriculture Award from the Farm and Industry Short Course Alumni in Wisconsin.
Abstract of lecture: Reproductive efficiency has long been known to be one of the keys to profitable dairy operations. However, genetic selection as well as management and feeding have generally been targeted at optimizing milk production in dairy cattle with reproduction left in the shadows. The reproductive efficiency of dairy cattle on US dairy farms reached a low in the year 2000 but has since been climbing back from the depths. This improvement has been primarily related to development of better management tools for reproduction. However, future dramatic improvements are possible, and even likely, as genomics provide powerful tools for selecting key physiology and metabolism traits that are associated with greater reproductive efficiency. In addition, improved nutritional programs, particularly of the transition period, hold great promise for optimizing the health and reproductive potential of lactating dairy cattle. The tangled web of interactions among hormonal concentrations, genetics, metabolic state, and well-being of cattle has been demonstrated by recent, reliable research. The challenge for researchers in this area is untangling the chronic and acute mechanisms that underlie reproductive efficiency in dairy cattle and using mechanistic insights to develop practical approaches to achieve consistent reproductive efficiency on dairy farms.
