QUESTION
The term “summer sterility” is associated with?
OPTIONS
(A) Cattle
(B) Pig
(C) Horse
(D) Ram
ANSWER
(A) Cattle
EXPLANATION
In cattle, summer sterility describes the seasonal reduction in reproductive performance associated with heat stress, including impaired estrous expression, oocyte quality, embryo survival, and semen quality. This is the conventional association intended by the question. Pigs and rams can also suffer heat-related infertility, and horses show seasonal reproduction, but those facts do not make summer sterility exclusive to cattle as a biological phenomenon.
