The Effect of Hemp Byproduct Supplementation on Beef Quality

Abstract

The supplementation of hempseed cake (hemp byproduct) could be considered an alternative protein and fiber source for ruminants such as cattle. Hempseed cake might be a successful alternative feed source due to cattle’s digestive abilities. Yet, the physiological effects caused by cannabinoids in hemp (cannabidiol [CBD] and (-)-Δ9-tetrahydrocannabinaol [THC]) are of concern. However, hemp with much less than 0.3% THC on a dry matter basis can remain a potential alternative feed ingredient. The objective of this study was to evaluate the significance of hempseed cake inclusion in a late finishing ration on carcass characteristics, meat quality characteristics, retail shelf-life, proximate analysis, and fatty acid profile of muscle food obtained from commercial beef heifers.
