“Timing of Artificial Insemination to Optimize Fertility” headlines the Oct. 7 Dairy Cattle Reproduction Council (DCRC) webinar. The free webinar starts at 12 p.m. Central time (USA/Canada). Paul Fricke, University of Wisconsin, will serve as the instructor for this one-hour webinar.

This webinar will overview the effect on pregnancy per artificial insemination (P/AI) of interval from induction of ovulation to timed artificial insemination (TAI) for cows submitted to a fertility program and the interval from the onset of estrous alert to artificial insemination for cows inseminated to estrous alert. Lactating dairy cows inseminated too early relative to a synchronized ovulation or too early or too late relative to the onset of estrous alert had fewer P/AI than cows inseminated from 13 to 23 hours. Further, optimal timing of AI relative to a synchronized ovulation or the onset of estrous alert in lactating dairy cows did not differ between conventional and sex-sorted semen.
Fricke was raised on his family’s row crop and dairy farm located near Papillion, Neb., where his father continues to farm today. After receiving a bachelor’s degree in animal science in 1988 from the University of Nebraska, Fricke went on to complete a master’s degree in 1992 and a PhD in 1996 in reproductive physiology from the department of animal sciences at North Dakota State University. He joined the faculty at the University of Wisconsin-Madison in 1998. His current position includes both research and extension responsibilities in dairy cattle reproduction. Fricke’s research program focuses on understanding the biology underlying the many reproductive problems of dairy cattle.

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. DCRC provides an unprecedented opportunity for all groups to work together to take dairy cattle reproduction to the next level.
