Precision nutrition: Choline & its impact on subclinical ketosis

In this free webinar, you will learn that subclinical ketosis is a costly problem than affects up to 60 percent of cows in early lactation, robbing profits throughout the lactation. Choline is essential for getting cows off to a strong start and helping manage fat metabolism during the all-important transition period.

Topics will include:
• Choline’s requirement in the diet of transition dairy cows
• Impact of subclinical ketosis on the overall health and profitability of the dairy herd

You'll learn about:
• Transition dairy cows are always deficient in choline
• Choline is important in fat metabolism, energy balance, reproduction and overall animal productivity
• Research has shown that choline improves phospholipid synthesis and increases rate of fat export out of the liver
• Subclinical ketosis (SCK) is defined as circulating ketone bodies without clinical signs of ketosis
• The prevalence of ketosis (snapshot) is between 15-30 percent for most U.S. dairies
• The incidence of ketosis (number of cows with high blood ketones during early lactation) between 30-60 percent for most U.S. dairies
• Ketosis occurs early in lactation, peak prevalence and incidence at 5 days in milk
• Cows with SCK give about 5-8 percent less milk during early lactation than those without SCK
• Cows with SCK at higher risk for metritis, displaced abomasums, removal early from herd in lactation and infertility
• Cost of each case of SCK between $50-$100
• Use of cowside blood test for BHBA allows for early detection & treatment of ketosis, as well as for herd-level monitoring for ketosis

Who should attend:
• Dairy nutritionists
• Dairy producers and managers

DR. GARRETT R. OETZEL University of Wisconsin-Madison School of Veterinary Medicine, Department of Medical Sciences, Associate Professor Education • Associate Professor of Food Animal Production Medicine • BS 1978, Ohio State University • DVM 1981, Ohio State University • MS 1985, University of Illinois Research Characterization of subacute rumen acidosis in dairy cattle; prevention of hypocalcemia in dairy cattle by manipulating dietary cation-anion difference and/or the oral administration of calcium supplements; effects of subclinical ketosis on dairy cow performance; direct-fed microbials. Responsibilities Clinical and teaching activities are in the area of applied dairy nutrition. Most of these activities include solving nutritional problems on dairy farms throughout Wisconsin. Clinical interests Clinical service is directly to dairy herds with nutritional problems. Herds throughout Wisconsin and neighboring states are consulted. Most of these consultations include a visit to the farm and a written report of the recommendations. Oetzel also is involved in delivering regular nutrition and production medicine services to one of the herds enrolled in the core herd program.

He has lectured on these topics in 17 foreign countries. He was a member of the National Research Council Subcommittee on Dairy Cattle Nutrition that was responsible for writing the Seventh Revised Edition (2001) of Nutrient Requirements of Dairy Cattle. In 2002, the Institute of Scientific Information (ISI) named him a Highly Cited Researcher. He has received numerous other awards, including the American Feed Industry Award (1994), Nutrition Professionals Applied Nutrition Award (2004), and Fellow (2010) from the American Dairy Science Association.
