QUESTION
Percentage of viable sperms per ejaculate in boar is?
OPTIONS
(A) 50%
(B) 60%
(C) 70%
(D) 80%
ANSWER
(D) 80%
EXPLANATION
Approximately 80% viable spermatozoa is the representative value intended for a good-quality fresh boar ejaculate. Viability means that sperm cells are alive, usually assessed through membrane-integrity staining, and is distinct from motility. The lower figures of 50%, 60%, and 70% indicate progressively poorer viability relative to this reference value, although actual percentages vary between animals and collections.
