Study Finds Feeding Industrial Hemp May Improve Livestock Health

A study by Kansas State University found that feeding cattle industrial hemp may have beneficial effects on their health: reduce stress and increase the times they lie down, reported K-State News.

The study was funded by a grant from the Agriculture and Food Research Initiative of the U.S. Department of Agriculture's National Institute of Food and Agriculture.

"Cattle experience a variety of stress and inflammation," said Michael Kleinhenz, assistant professor of beef production medicine at the K-State College of Veterinary Medicine.

"Our most recent data shows how cannabinoids via industrial hemp decreased the stress hormone cortisol as well as the inflammatory biomarker prostaglandin E2. This shows that hemp containing cannabidiolic acid, or CBDA, may decrease stress and inflammation in cattle," Kleinhenz said. "Thus, hemp may be a natural way to decrease stress and inflammation related to production practices such as transportation and weaning."

Kleinhenz published the results of his study, "Short term feeding of industrial hemp with a high cannabidiolic acid (CBDA) content increases lying behavior and reduces biomarkers of stress and inflammation in Holstein steers," in Scientific Reports.

"Our new research helps us better understand how cannabinoids present in industrial hemp interact with bovine physiology and pharmacology," Kleinhenz added. "For instance, we now know that repeated daily doses of CBDA via feeding hemp do not result in accumulation of cannabinoids in the blood. Additionally, it solidified previous research and shows that each cannabinoid has its own absorption and elimination profile."

Another benefit observed when feeding cattle industrial hemp is that they lie down more, which can help them ruminate and produce saliva.

"If hemp is to be utilized as an ingredient in the ration of cattle, it is prudent to know and understand the pharmacokinetics and potential biological effects of cattle exposed to repeated doses of cannabinoids present in industrial hemp," Kleinhenz said. "The initial data we have collected is essential should industrial hemp and its by-products are to be considered by the U.S. Food and Drug Administration and the Association of American Feed Control Officials. Further work is needed to determine if cannabinoids can alter the stress response in cattle during stressful times such as transportation and weaning, but we hope this research is a step forward in the right direction."
