A study by Kansas State University's Michael Kleinhenz has found that feeding cattle industrial hemp can help reduce stress and inflammation in the animals. The study indicated that hemp feeding led to lower cortisol and inflammatory marker levels in cattle, and also increased the amount of time the animals spent lying down for rumination. The research also noted that repeated doses of high cannabidiolic acid (CBDA) from hemp did not result in cannabinoid accumulation in the blood. Kleinhenz emphasized the need for further research to determine if hemp-derived cannabinoids can effectively alter stress response in cattle during key periods like transportation and weaning.
