Long-Term Effects of Feeding High-Lignin Forage to Ruminants: Implications for Productivity, Health, and Sustainability
Abstract: The long-term feeding of high-lignin forage to ruminants can significantly impact various aspects of animal performance, health, and environmental sustainability. Lignin, a complex phenolic compound present in plant cell walls, is indigestible by rumen microbes, leading to reduced fiber digestibility and decreased nutrient utilization. Over time, feeding ruminants with forages high in lignin results in a decline in voluntary dry matter intake (DMI), inefficient energy and protein absorption, and suboptimal …
