Jan. 10: Optimizing Use of Sexed Semen in Dairy Herds
Dairy Cattle Reproduction Extension Specialist Paul Fricke and Regional Dairy Educator Ryan Sterry will
discuss the latest trends in how farms are using sexed and beef semen in dairy herds in Wisconsin and the upper Midwest. Paul will then present the latest data from UW-Madison on how to maximize fertility when using sexed semen to inseminate nonlactating dairy heifers, primiparous Holstein cows, and lactating Jersey cows.
Jan. 24: Factors Impacting Fertility from Genomics to Aspirin
Dairy Educator Lyssa Seefeldt will talk how a successful transition period sets up a dairy cow for a stress-free lactation and better conception rates. She will highlight a few things producers can think about to create that successful transition. Prof. Francisco Peñagaricano will focus on how the advent of genomics in the last 15 years has revolutionized dairy cattle breeding, enabling more rapid genetic progress. Genomics facilitates the selection of novel traits that are important however too difficult or expensive to measure on the entire population. This could allow the selection of new fertility traits that more closely describe cows’ reproductive physiology and ultimately benefit the improvement of fertility in dairy cows. Rounding out the day, Dairy Educator Heather Schlesser will touch on aspirin after calving. Does aspirin, a nonsteroidal anti-inflammatory drug benefit a cow when given during calving? Her presentation will seek to answer this question.
Jan. 31: Tools for Your Toolkit to Keep Animals Healthy
Extension Specialist and Prof. Neslihan Akdeniz Onuki will focus on proper fan selection and maintenance to reduce ventilation costs and ventilation-related greenhouse gas emissions from dairy buildings. She will provide a few examples of supplemental cooling systems, which can save energy while maintaining healthy building conditions for cattle. Dairy Systems Management Specialist Victor Cabrera and Postdoctoral Researcher Tadeu da Silva will launch The EZ Dairy Enviro-Money. This is a highly user-friendly, whole farm, environmental and economic assessment tool for dairy farmers and other stakeholders. They will explain the tool, demonstrate its use, and show how to build scenarios to answer what-if questions.
Feb. 7: Milk Quality and Production: Opportunities and Threats
Lactation Physiology and Obstetrics & Gynecology Prof. Laura Hernandez recently completed research aimed to determine if increased cisternal milk impacted milk yield given that in traditional milking systems, take offs are set according to the fastest milking quarters. Are the possible negative effects on quarters that are not completely milked out? Wisconsin Veterinary Diagnostic Laboratory Epidemiologist Don Sockett will give an update on the work being done in the lab and challenges he sees emerging in the dairy industry. One of the topics he will present on is the emerging threat of Prototheca Bovis Mastitis.
