QUESTION
The acid required for good quality silage is?
OPTIONS
(A) Acetic acid
(B) Butyric acid
(C) Propionic acid
(D) Lactic acid
ANSWER
(D) Lactic acid
EXPLANATION
Lactic acid is the principal desirable acid produced during successful ensiling and is responsible for rapid pH reduction and preservation of the forage. Acetic acid may be produced in smaller amounts, whereas butyric acid indicates undesirable clostridial fermentation and propionic acid is not the principal acid of good silage.
