Description
Hemp (Cannabis sativa L.) has been a valuable species for humans throughout history due to its adaptability and diverse uses. Farmers are interested in hemp as a forage and feedstuff due to its unique nutritional properties and fast summer production. Moreover, the presence of cannabinoids in leaf and bud tissues may provide pharmacological benefits to animal health, productivity, and product quality under different regulatory frameworks. This study examined two hemp cultivars, Grandi and Joey, solely as forage crops, and samples were taken at different growth stages in Blacksburg, VA, USA, in 2021. The highest biomass production of 1.41 tons per acre for Grandi and Joey was recorded two months after establishment. The samples taken at different growth stages of Grandi and Joey contained 20 to 31% CP, 24 to 44% NDF, 22 to 38% ADF, and 4 to 9% lignin. These preliminary results suggest that hemp has the potential to be used as a forage crop. However, more research is needed to address hemp management, including field establishment and production management, harvest timing for optimum tonnage and forage quality, and animal intake and performance studies.
