Research by Volac Wilmar Feed Ingredients at the National University of Singapore has determined that the granule size of calcium salts has a direct effect on the nutritional value of these supplements for dairy cows.

Calcium salts are rumen-protected fat supplements which facilitate addition of energy-dense fat to diets without negative effects on fibre digestibility in the rumen and are the only effective method of delivering unsaturated fatty acids, such as oleic acid (C18:1), through the rumen for absorption in the small intestine. Oleic acid is a highly functional fatty acid which improves diet fat digestibility, egg quality and influences partitioning of nutrients in the dairy cow.

On Thursday, April 30 at 9 am (GMT) Volac Wilmar Feed Ingredients will be hosting a virtual press briefing to present new research data on this topic and to consider the benefits at farm level for nutrition of dairy cows. Is this something you would be interested in covering for Hoards Dairyman? I understand it is not ideal for US time zones, so we will be sending out a recording of the event to those unable to attend, along with a press release.

Press Briefing Topics

Why feed fat supplements?

Dr Richard Kirkland, Global Technical Manager for Volac Wilmar Feed Ingredients

  • The importance of fat (fatty acids) in dairy rations
  • Why fat supplements need to be rumen-protected
  • Scientific research findings on the effect of granule size of calcium salts on stability under rumen-like conditions

We don’t feed ‘fat’, we feed ‘fatty acids’

Professor John Newbold, PhD, Professor of Dairy Nutrition at Scotland’s Rural College (SRUC)

  • Delivery of C16:0 (palmitic acid) and C18:1 (oleic acid) through the rumen to the small intestine
  • Nutritional benefits of C16:0 and C18:1 including impact on digestibility of dietary fat, milk fat production, fertility and partitioning of nutrients in the cow

Each presentation will be approximately 15 minutes long and conclude with a Q&A session.

A video recording and press release will be distributed after the event.
