Study investigates hemp biomass as potential livestock feed
A recent study published in the Journal of Dairy Science is exploring the feasibility of incorporating cannabidiol (CBD), a by-product of hemp cultivation, into the diets of dairy cows, shedding light on its safety and impact on milk production, EurekAlert! reported.
Led by Dr Massimo Bionaz from Oregon State University, the international research team conducted the first-of-its-kind study using biomass leftover from CBD extraction. Despite concerns about regulatory approval for feeding hemp to livestock, the study delves into the nutritional value and potential benefits of spent hemp biomass.
Dr Bionaz highlighted the promising nutritional properties of hemp biomass, citing its anti-inflammatory and antioxidant characteristics, which could enhance animal health and performance. Additionally, amid market volatility, the dairy industry is keen on exploring alternative feed sources that offer sustainability and efficiency benefits.
The study involved 18 late-lactation Jersey cattle fed diets supplemented with spent hemp biomass or alfalfa meal over an eight-week period. While the cattle consuming hemp biomass exhibited decreased feed intake, milk production remained unaffected, indicating the safety of this feed ingredient.
Although the distinct odour of hemp biomass may deter cattle initially, the study suggests that they could adapt over time, potentially leading to increased efficiency. While further research is needed, this study lays the groundwork for considering spent hemp biomass as a viable option in dairy cattle diets.
