Abstract:
Plant by-products obtained from agro-industrial processes require valorisation to
demonstrate their potential for enhancing animal health, meat production, and shelf
life extension. One example is the fast-growing hemp industry, which produces seeds,
leaves, seed oil, and cake. Studies on the nutritional value of hempseed cake have
shown it can be a valuable source of protein in ruminant diets. However, there is
limited documentation on the bioavailability and bioefficacy of hemp phytochemicals for
improving ruminant health, production, and extending meat shelf life. The current review
provides an overview of existing information on nutrient and phytochemical composition
of hemp by-products, their bioavailability, and bioefficacy, and explores current limitations
and prospects regarding their valorisation.
