QUESTION
In severe grain engorgement, the ruminal pH becomes?
OPTIONS
(A) 6
(B) 4
(C) 7.5
(D) 9
ANSWER
(B) 4
EXPLANATION
Severe grain engorgement causes rapid fermentation of carbohydrate and accumulation of lactic acid, often lowering ruminal pH to around 4 or even less. A pH of 6 is only mildly acidic, while 7.5 or 9 would indicate alkaline conditions rather than acute lactic acidosis.
