Livestock Poisoning Possible From Wilting Black (Wild) Cherry Leaves

 

Severe thunderstorms that developed across southwest Michigan on Saturday, Aug. 20, 2016, turned violent as tornados ripped through parts of Van Buren, Allegan, Kent and Ottawa counties. Areas particularly hard hit were Bangor and Grand Junction in western Van Buren County, and Hamilton in western Allegan County. The high winds caused widespread damage to trees, homes and other structures. As growers are out cleaning up storm damage, Michigan State University Extension advises livestock producers to be aware that some of the storm-damaged trees may pose a livestock poisoning risk.

 

 

 

The leaves of wild black cherry trees, which are a very common fencerow and woodlot species in southwest Michigan, can cause a lethal poisoning risk if grazing animals consume wilted leaves. The toxic component in the leaves is prussic acid, a hydrogen cyanide toxin that is only formed when glycosides in the leaves are combined with hydrolytic enzymes. Under normal circumstances, the two components are stored in separate tissues, but can become poisonous in storm-damaged wilted cherry leaves.

 

With tornadoes, it is possible for branches to be carried quite some distance. We would encourage producers to check branches and trees down in their pastures to make sure that wild cherry is not in areas that livestock can get access to.

 

 

“Cattle Grazing: Summer Storms and Wild Cherry Trees,” written by Ohio State University Extension educator Rory Lewandowski and published at Dairy Herd, states that as little as 1.2 to 4.8 pounds of wilted black cherry leaves could constitute a lethal dose for a 1,200 pound dairy cow. To protect grazing livestock, limbs with wilted leaves should be removed from pasture areas. Lewandowski recommends the animals be removed from the pastures until the damaged black cherry branches have been removed or the leaves become dried up and turn completely brown.

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
