Abstract
Rumen biohydrogenation is a microbial-driven process that converts unsaturated fatty acids (UFA) into saturated fatty acids (SFA), significantly reducing the content of beneficial polyunsaturated fatty acids (PUFA) in ruminant-derived products such as meat and milk. High levels of SFA in these products are associated with increased risk of cardiovascular diseases, prompting the need for nutritional strategies that can enhance the health profile of ruminant products. One promising approach is the use of biohydrogenation inhibitors, particularly natural compounds found in tropical forage plants, to protect UFAs from rumen microbial saturation. This strategy not only improves the fatty acid profile of ruminant products but also supports methane mitigation and feed efficiency. This paper explores the mechanisms of biohydrogenation, identifies potential plant-based inhibitors such as polyphenol oxidase (PPO), and discusses innovation opportunities in ruminant feeding to produce healthier animal products. The development of biohydrogenation-inhibiting feed additives presents a sustainable and functional solution aligned with consumer demand for nutritious and environmentally friendly animal products.
