Abstract: Feeding constitutes a significant portion of the overall costs in ruminant production. High-producing dairy animals necessitate a greater nutrient composition in their diet that bypass rumen without degradation to provide essential nutrients directly at the intestinal level. The incorporation of bypass nutrients in ruminant diet is important for increasing the energy content of the diet. However, productivity is often limited by inadequate nutrition, especially in terms of protein and energy supply. Bypass nutrients, which escape ruminal degradation and are absorbed in the small intestine, play a vital role in enhancing immune function, reproductive efficiency, and overall production performance in ruminants. Moreover, they have significant implications for productivity, particularly regarding milk yield, growth rate and overall performance, as they ensure a consistent supply of critical nutrients directly absorbed in the small intestine.
