The first paper ever published on the use of spent hemp biomass with ruminant was published in the Journal of Animal Science
Our research revealed that spent hemp biomass (SHB) can be a safe feed ingredient for lambs. We obsevred however a low palatability of the SHB decreasing feed intake, especially if fed at 20% level in the diet. However, the feed intake was back to the level fo the control after 1 month of feeding SHB. Feeding SHB had an effect on metabolism and appeared to improve the response to oxidative stress. Not significant efefct on meat quality or immune system were detected. If you want more details the paper is available here.
