QUESTION
Very good silage should have pH ranging from?
OPTIONS
(A) 4.2 to 4.5
(B) 4.5 to 4.8
(C) 3.7 to 4.2
(D) 4.8 to 5.0
ANSWER
(C) 3.7 to 4.2
EXPLANATION
Very good silage generally has a pH around 3.7–4.2, reflecting successful lactic-acid fermentation and good preservation of the forage. Higher pH ranges such as 4.2–5.0 are progressively less desirable because inadequate acidification permits undesirable microbial activity and poorer preservation.
