QUESTION
Consider the following with regards to silent heat:
(1) It refers to normal follicular development and ovulation without the behavioural signs of oestrus.
(2) Its frequency increase as lactation progresses.
(3) True silent heat may not be detected through rectal palpation of ovaries.
Which of the statements given above is/are correct?
OPTIONS
(A) 1 only
(B) 2 only
(C) 3 only
(D) 1, 2 and 3
ANSWER
(A) 1 only
EXPLANATION
Silent heat refers to follicular development and ovulation without obvious behavioral estrus, so statement 1 is valid. It is particularly associated with early postpartum cycles rather than an obligatory increase as lactation progresses. Serial ovarian examination can detect changes consistent with ovulation and corpus luteum formation even when behavior is absent, making statement 3 misleading as a general claim. Thus, only statement 1 is supported.
