Brief Project Summary:

Dietary fat helps support high energy demands of lactating cows, but dairy cows have limited ability to digest dietary fat. Oleic acid is a natural emulsifier that helps break apart fat and aids absorption. It has been shown to increase fat digestibility in cows, developing strong interest in the oleic acid concentration of fat supplements. However, the effect of high oleic soybeans on fat digestion has not been investigated. This project measures the effect of high oleic soybeans on total tract digestibility of fatty acids in lactating dairy cows, demonstrating an additional unique benefit of high oleic soybeans to increase energy intake through increasing fat absorption.

Key Benefactors:
farmers, agronomists, extension agents, livestock farmers, dairy industry, livestock nutritionists

Information And Results
Final Project Results

Updated March 31, 2021:
A no cost extension has been provided for the experiment to allow completion of data analysis. A delay was a result of both covid-19 restrictions and equipment break-down in the lab. We have received analysis of sample NDF and iNDF and have nearly completed the fatty acid analysis to allow final data analysis. This will be completed over the next few weeks.

Final results will be provided after completion of data analysis.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
