Progressive Dairy: May 2020

As part of the series of publications in Progressive Dairy, Dr. Heather White and Michael DeVeth continue to discuss nutritional interventions in the article titled “Nutritional intervention improves feed efficiency and saves money.” Throughout the article, discussion on feed efficiency, its importance, and what it looks like when a farm improves feed efficiency are examined.

This article complements a research paper accepted to Journal of Dairy Science in March 2020 titled “Postpartum fermented ammoniated condensed whey supplementation altered nutrient partitioning to support hepatic metabolism,” which is the companion research paper to the Editor’s Choice publication in March 2019.

Progressive Dairy: Feb 2020

A follow-up article has been published in Progressive Dairy called “Feed efficiency and metabolic health: How might we improve them both in the transition cow?“. Dr. Rafael Caputo Oliveira was also an author for this new article, as it explores the calculated feed and nitrogen efficiency, as well as circulating insulin concentrations during the transition to lactation period. The data comes from the manuscript “Postpartum supplementation of fermented ammoniated condensed whey improved feed efficiency and plasma metabolite profile” which was Editor’s Choice in March 2019 in the Journal of Dairy Science.

This article complements a previous article in which Dr. Heather White and Michael de Veth, Vice President of Fermented Nutrition, explored how and why Glucoboost, the product being discussed, is beneficial to transition cows.


Progressive Dairy: Dec 2019

In the most recent issue of Progressive Dairy, Dr. Heather White was formally mentioned for two things: becoming the Dairy Innovation Hub faculty director and researching the effects of ammonium lactate product in transition dairy cows.

The former discusses the advisory council, which consists of 11 members representing different areas of dairy (be it cheesemaking, farming, protecting consumers, etc). These members come from various backgrounds, yet all share a common goal. Read more about their current positions!

The latter was written in conjunction with Michael de Veth, who is Vice President of Fermented Nutrition. This article, “Uncovering the hidden glucose source cows need,” gives an abbreviated background of how the GlucoBoost product works and why it would be beneficial to transition cows. A follow-up article will be published in Progressive Dairy in a future issue.

Overview of Subclinical Ketosis Talk at Form-a-Feed Conference

Dr. Heather White had given a talk at the annual Form-a-Feed conference in Red Wing, MN in January 2019 on subclinical ketosis. Her topics included defining specificity vs. sensitivity and how it relates to diagnosing cows on farm, as well as touching upon some of her research which has demonstrated to have potentially positive health outcomes shortly after calving in transition cows. Jenna Hurty-Pearson wrote an article on the talk, which is found in the most recent issue of Progressive Dairyman. Click here to read more on the overview of Dr. White’s talk.

The Culmination of a Lot of Hard Work and a Great Collaborative Team — The KetoMonitor

A great team effort resulted in the release of KetoMonitor yesterday, a tool that provides a herd-level ketosis prevalence indicator using data collected during monthly milk testing. This tool will aid producers in making critical nutrition and management decisions to improve milk production and animal health. See the “On-Farm Resources” tab above and AgSourceKetoMonitor for more information.

AgSource Profit Tip
Research has shown that ketosis (clinical and subclincial) affects 40 to 60% of dairy cows, at an average cost of $289 per case. Cows with ketosis not only produce less milk, but are more likely to develop other health related issues such as a displaced abomasum, fatty liver, and an increased chance of herd removal in the first 30 days. Traditionally, monitoring clinical and sub-clinical ketosis has been difficult and time consuming because most detection methods involve testing individual fresh cows on a weekly basis. However, thanks to new research done by the University of Wisconsin Dairy Science Department and School of Veterinary Medicine, under the leadership of Dr. Heather White, Dr. Gary Oetzel, and Tawny Chandler, in cooperation with AgSource, your DHI milk sample can now be used to evaluate monthly ketosis prevalence in your herd.
AgSource’s KetoMonitor™, introduced on January 28th, is a new, comprehensive tool that combines laboratory analysis and individual cow data collected on test day to provide producers with a report that will estimate a herd’s ketosis prevalence. This report evaluates Early Fresh (5-11 DIM) and Overall (5-20 DIM) prevalence levels for 1st and 2nd+ Lactation groups. The KetoMonitor™ is designed to alert you to any changes that may have an impact on transition cow health, guide management and nutrition decisions and customize on farm blood testing protocols. Although it is not designed to be an individual cow test, it will also flag early fresh cows that are likely to have ketosis.
