The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Canine reproductive endocrinology: anovulatory follicular waves in pubertal bitches produce interrupted 'split heat' cycles.
Step 2: Detailed Explanation:
In small animal theriogenology and canine gynecology:
- Split Estrus (Split Heat): A physiological reproductive phenomenon occurring most commonly in young, pubertal Bitches during their first or second estrous cycle.
- A follicular wave initiates proestrus signs (vulvar swelling and serosanguineous bloody vaginal discharge) with male attractiveness, but follicles regress prematurely without reaching the LH surge threshold and without ovulating.
- After a quiescent lull of 2 to 6 weeks, a second fertile follicular wave develops, successfully culminating in LH surge and ovulation.
Step 3: Final Answer:
Hence, split estrus is seen in Bitch, corresponding to option (D).
