What is the function of buffers in animal feed?

• A. To decrease pH caused by volatile fatty acids without significantly increasing ruminal pH
• B. To increase palatability
• C. To add minerals
• D. To boost energy

Answer: (A)

Buffers in animal feed act to stabilize the rumen environment by counteracting the acidity produced when microbes convert feed into volatile fatty acids. As fermentation generates acids, the rumen tends to become more acidic, which can harm beneficial microbes and fiber digestion. Buffers supply conjugate bases (such as bicarbonate or phosphate) that neutralize those hydrogen ions, helping to keep rumen pH from dropping too low and staying within a range that supports healthy microbial activity. They aren’t intended to supply energy, add minerals as a primary function, or directly improve palatability; their main job is to resist pH changes and keep the fermentation space balanced without causing a large pH increase.
