What are volatile fatty acids (VFAs) recognized as regarding Zebu ruminal fermentation?
Answer
The cow's primary energy source.
The entire purpose of the fermentation process occurring within the Zebu's rumen, driven by its microbial population, is the efficient breakdown of complex carbohydrates found in roughage. The result of this microbial action is the production of short-chain organic acids known as volatile fatty acids (VFAs). These VFAs, which include compounds like acetate, propionate, and butyrate, are absorbed directly through the rumen wall into the bloodstream. They are then metabolized by the animal's body tissues, serving as the fundamental and primary source of metabolic energy that sustains the Zebu's body functions and production.
