🐄 Cow Rumen pH and Ration Balance: Hay vs Grain, Saliva Buffering and Subacute Acidosis Lab

Feed a dairy cow hay and grain and watch a cutaway rumen: starch and fibre fermentation, VFA absorption, a charge-balance pH solved from saliva buffering and chewing time, the pH 5.6 subacute acidosis threshold, intake, forage:concentrate ratio and milk response. An experiment sweeps the forage share against an acidosis limit.
