Description
Zahra Asadollahi Seyedabadi and co-authors examined how feed ferments inside the stomachs of cattle and sheep, using lab glassware that traps the gas released. Their 2026 PLOS One study compared mixed rations with different shares of roughage and concentrate feed, some with added buffers that keep acidity steady.
Four curve-fitting formulas were tried against the gas readings, and none won in every case. S-shaped curves matched buffered feeds best, while simpler rising curves suited rich, unbuffered feeds. Added buffers steadied acidity, raised total gas, and changed the mix of acids formed. The lesson is practical: pick the math model that fits the diet being tested.
