Utilization, extraction of energy and synthesis of various micronutrients through dietary lipids in ruminants is solely dependent upon rumen microbial efficacy. Rumen microbes are not only the pioneer of lipid digestion, but also the key factor to decide the physical & biochemical characteristics of input dietary lipids owing to the lipolysis and followed by biohydrogenation of dietary lipid through rumen microbes. Optimal microbial balance and proper scientific requirement of dietary lipids influences the digestibility and utilization of dietary lipids. Thus, aforesaid article developed to discuss key insight considerations of rumen microbes to utilizedietary lipidsin ruminants.
